Cancer is one of those terms that everyone knows, and most people have a story that pops in to their mind when they hear the term. Whether it be about their own battle with cancer or a battle they experienced second hand through a friend or family member, almost everyone has an experience with cancer. I myself have never not been surrounded by it, even from a young age. In my own personal family history, I have numerous different types of cancer ranging both on my father and mother’s side. Cancer, for me, is almost an inevitable fate. That is one of the reasons why this particular video really stuck out to me. How can we, as mere mortals, prevent something so much more destructive than ourselves? The idea of being able to prevent cancer is something that people have thought about for decades. Cancer prevention is an attainable thing to a certain extent. A healthy diet and lifestyle can greatly impact your risk of getting cancer. Whether it be eating healthier or staying out of the sun during the summer, we all know the common preventative measures taken in order to reduce our risk of getting one of the many different forms of cancer. It has recently been discussed that these “preventative measures” are actually extremely underestimated in their abilities to help prevent it though. But can we really prevent cancer in all of its entirety? I mean look at my situation, I am surrounded by cancer on both sides of my family tree. Genetically speaking, the probability that I will get some form of cancer at some point in my life is extremely high. So does that mean I shouldn’t follow these preventative steps because, even if I carefully follow all of the preventive measures that I possibly can, the likelihood of me getting cancer is basically 99.9%? From a girl who has accepted that I will have cancer at some point in my life I still plan on taking any preventative steps that I can because, well, why not? Maybe I will be in the 0.1% that magically, against all odds, doesn’t get cancer because I did everything I could to prevent it. And maybe if all of society thought this way about cancer, and other health issues, the statistics could drop and maybe then we wouldn’t all have a “cancer story” that pops into our heads when we hear that word.
Omg, this has been 5 years ago. But I just wanna say that I totally agreed with your mindset! Even tho I'm in the low risk group, I have an anxiety about cancer. Anyway, how is it going now for you? I hope you are in a healthy condition!
The thing I hate most about all this cancer prevention stuff that has gone a bit crazy and produced zealots that think they can avoid cancer by doing everything right is that sometimes, cancer is totally random and that sucks. My mom was 46 when she was diagnosed with stage 2-3 (they couldn't agree on the number) breast cancer. So many people would quiz her on all this prevention stuff until they started getting into the strange stuff like using paraben based soap and eating sugar to try to find a reason it happened to her and wouldn't happen to them. She wasn't a smoker, overweight, tall, inactive, immunocompromised, or from a family prone to cancer, and young. It was random misfortune and some people just refuse to accept that it could happen to them even if they did everything "right".
I just wanted to say I love your channel! I'm going to university to study statistics and biology, and your focusing about statistical trials in medicine really excites me about the future career I want to have. It also shows everyone how important well designed studies are in medicine, and how bad studies can truly flip findings on their head. Thanks for a great channel!
I'm in the low risk group! Woo! But I'm planning on becoming a health professional.. so I'll probably be so stressed I stop exercising and start eating. I recently started cycling to work and it rules. I save 30 minutes a day, I get exercise, and I enjoy it.
***** that depends on how fast you cycle and how far you are from work. I can cycle leisurely, get an aerobic workout, cycle quickly, get an anerobic workout. I normally get my heart rate up to 120, which is just what I need. :) It is 40 minutes a day of proper exercise, for free. Jogging does permanent damage to your knees, cycling is GOOD for your knees. (unless your seat is too low, you shouldn't be able to touch the ground with both feet while sitting on the seat, for a start) If you want to spend as much time cycling as you would walking you can just take the long way to work, of course, and walking to work was only ever light exercise for me, it didn't allow me to hit the minimum.
I am in the low risk group as I don't drink or smoke, don't take dangerous drugs, exercise every day and maintain a healthy weight. The one thing that does bother me though is vehicle fumes and their negative effect on health and cancer risk from those, as its often hard to avoid vehicles these days unless you live in the middle of a wilderness somewhere away from most vehicles. I watched a program on TV earlier this year and have also read studies that showed that, even if your inside a car, you can still be exposed to lots of harmful toxins and driving in an electric car was better for your health than a car that used fossil fuels. Could you make a video on vehicle pollution and health?
Love the video! Could you do a video on menopause for my mum haha. I think a lot of women get confused on the advice given to them by other women and on the Internet.
We know that the risk of cancers like lung cancer or skin cancer are increased by smoking or excessive exposure to the sun, but there is still so much about cancer that we haven't yet figured out. I agree with what the video say about being careful with how much weight we put on lifestyle causes of cancer. The idea that most cancer is preventable should help influence one's lifestyle choices hopefully, as long as it doesn't get to the point of not treating cancer that could have been prevented with the same diligence that we treat less avoidable cancers. I believe that this is one of those 'slippery slope' situations that we should try and avoid. However, it is also important to spread awareness about ways we can live a more "low-risk" lifestyle.
Hi Krystal, thank you for your comment! I agree with a lot of what you have to say. I think if people know how they can reduce their chances of getting cancer can lead to more "low-risk" lifestyles as you had mentioned, which in my opinion are just overall healthier with maybe a few exceptions. As someone that works in healthcare, it is important to make sure your patients understand the risk that come with certain lifestyle choices. It is our responsibility to spread the awareness of how certain lifestyle choices can increase or decrease our risk of getting cancer. One "biggy" is obviously smoking. We, in the end, have the ultimate decision about the lifestyle choices that we make and the consequences that come with them, good or bad. Promoting this awareness should not change how we screen or treat cancer. Screening should never be replaced with "healthy" lifestyle choices. There are many people out there that lived extremely healthy lifestyles but still ended up with cancer. Their lives would have most likely been cut short by runaway cancer if it weren't for certain screening tests done that ended up catching the cancer. If we can prevent it, it is best to catch it as early as possible. I think the best way to prevent cancer and its consequences is by doing all we can do prevent it by our lifestyle choices and then screening tests and other labs to stop it in its early stages! Thanks for your comment!
+Healthcare Triage Hey HCT! I've enjoyed watching your videos for a long time (really like how informative and evidence based they are). Would you ever consider doing other videos similar to this one about other illnesses eg. "You Can Do a Lot to Prevent Some Forms of Dementia". Also, if you had any advice or know of any studies that might provide us viewers with any practical guidance over what we can do to prevent or lessen the risk of developing such conditions (past eating, sleeping or exercising right and wearing sun cream), I have a hunch people would be interested in tuning in to learn about that. Just a thought. Thanks again for all the great content! :D
Many people have a misconception about cancer, and that if you get cancer you just have "bad luck" and cannot prevent it. People often talk about cancer being one of their biggest fear but do they do anything to attempt to prevent cancer? Fitting in the four categories of the low-risk of cancer isn't anything too extreme. As discussed in the video the four requirements are: never smoking or have quit for over 5 years, moderately consumption of alcohol which was 1 drink or less per day for women and 2 drinks or less for men, having a BMI between 18.5 and 27.5, and completing 150 minutes of moderate activity or 75 minutes of strenuous activity. These requirements aren't as difficult as most people like to assume, and are quite reasonable. I think the problem is that people like to make up too many excuses for trying to meet these requirements. Some many argue that they don't have enough time to complete 150 minutes a week of moderate exercise but that breaks down to less than 30 minutes a day of exercise. That may seem like a lot, but think of how many minutes you spend watching tv, or scrolling through Facebook a day. Also, you don't have to be "skinny" to fit into the low-risk group either. The BMI for overweight as mentioned has a cut off of 25, whereas the requirement says no more than 27.5 BMI which means you just cannot be obese which is 30 BMI. Not smoking should be a reasonable requirement, as well as the moderate drinking. This does not say that you have to refrain from drinking, but rather drink a less amount. I think if more people knew about these requirements that they would try to meet them before they think it is impossible to quit drinking, or workout throughout the week. The next point that stood out in this video is that although meeting those four requirements that were discussed, it does not completely eliminate your risk for cancer. It was stated that overall 25% of cancer in women and 33% of cancer in men could be prevented. That means that about 75% of cancer in women and 67% of cancer in men cannot be prevented. There is still a higher percentage of cancer that cannot be prevented but you cannot look at it from the negative viewpoint. These percentages do not mean don't try to prevent cancer. It is still beneficial to attempt to meet these four requirements not only to prevent cancer but to also prevent other health issues by living a healthier life.
We all get cancerous cells at some point, but the immune system usually recognizes it and kills it before it gets out of hand. What we call cancer is actually just too much cancer... we all get cancer all the time. (a book called Genome and a book called Why we get Sick.. those are my sources) I did a course on exercise and.. wow.. do we need to exercise Also, being sedentary for long periods is bad, even if you exercise afterwards. Get up and move around every half hour!
Can stop feeding cancerous cells with a crappy diet. Every study on exercise says we need to do it more.. 30 mins/day is better than none, 45 better than 30, 90 better than 45.. they've not found an upper bound of diminishing returns...
Hi Dr. Carroll, I love watching your Healthcare Triage segments, I think they do a wonderful job at informing the public on relevant health related news of today. I am curious if you'd do a video on Physician Suicide and your thoughts on why it happens and how society might address this issue. Thank you!
Some people think that cancer is the greatest cause of death when really, it is cardiovascular disease. As mentioned in the video, some cancers are preventable while others are not. I think it is important that people know how preventable some cancers can be, such as skin cancer. In the summer, everyone likes to be tan and have bronze looking skin. But do they really consider how harmful it can be to your body? A lot of people will risk getting skin cancer from UV radiation when they want to look tan by either sitting outside in the sunlight or even going to a tanning salon. Something as simple as wearing sunscreen can make a huge difference on someone. I know I have a risk of getting cancer because my dad had been diagnosed with it. Not only do I know that I have a chance of getting cancer, but I also know that it can be prevented. Eating healthy and exercising is an effective way to prevent some cancers and since most people are worried that they will be diagnosed with cancer, everyone should be informed that sometimes those simple steps can prevent such a life threatening situation. Unfortunately, some cancers cannot be prevented as easily because they are inherited. Just because some cancers can be inherited, doesn’t mean that people shouldn’t try the steps to prevent it anyway. Cancer is such a scary thing to witness whether it be first hand, or second hand through a family member or friend. Anyone can get cancer, but anyone can also help reduce the risk of getting cancer. With the help of chemotherapy and radiation treatment, some people are cured of cancer. The cure for cancer has been being tested and experimented for so long and sometimes doesn’t always work. Instead of waiting to see if they will be diagnosed with cancer, people should take the advice and use the steps to help reduce your risk of getting cancer.
Didn't say much about breast cancer. In fact, it seems the only thing ever given was to perform self - breast exams and get mammograms. One presentation that was considered to make me low risk was fibrocystic breast disorder (Lumpy - bumpy breasts). But I got breast cancer in 2016 as a 52-year - old. And my self - examinations didn't seem to tell me anything till one day I woke up on my belly, adjusted my boobs for comfort, and found a hazel nut - sized lump clearly on the outside perimeter of my breast, 12-o'clock high, if you will. I learned so much about cancer during my treatment, and I found when I was in the grocery buying produce, I had cravings. I would search in Google regarding each food and cancer, and in every case, I found that there were chemicals in these fruits and veggies were being studied as candidates for creating new chemo medicines. I didn't stop chemo and try to use only foods to cure it. If you can detect cancer, it's too late for that. But the cravings were fascinating to me. I'm a"kitchen sink" person: I'll throw everything at a problem, even the kitchen sink if I think it would help. So I followed my cravings. Something I DIDN'T crave, strangely, was citrus fruits. Many cancer patients protest that oranges don't taste right. And I think people want to eat them because of vitamin C. That's all well and good, but vitamin C is in all fresh fruits AND vegetables. I wanted cantaloupe, broccoli, cauliflower, rutabaga, bell peppers, grapes (especially black), blueberries, soybeans (edamame), tree nuts and peanuts, cabbage, beets, chicken AND pork (I wanted chicken soup so bad). Celery (I don't eat it most times) black beans and great northern beans, apples and Romaine lettuce, peas, potatoes, Braunschweiger, Cream of Wheat made with milk, eggs, and others. I did not prevent myself from eating meat, and my brother in law would get me a Rally's (Checkers) Baconzilla with 2 beef patties and bacon when he'd shop for me (and then made sure I ate it). Eat fruits and veggies period. These chemicals that are being studied for chemotherapy treatment are available to everyone. The truth is, there is always one cell or another going rogue in your body, and that's what the immune system takes care of. When you eat the whole food, you get the benefit of whatever chemicals we don't know about, yet, and that can give us a benefit beyond what science knows yet.
most cancers are, in fact, due to stochastic mutations = bad luck. the study in question gets this right. they estimate about 1/3 of cancers are due to extrinsic factors, which is congruent with other estimates. 70-90% from the nature article significantly exceeds most estimates. "If you interpret Vogelstein’s estimate the way it’s been represented in the press and by Vogelstein, as representing the percentage of cancers that are due primarily to “chance” and thus not related to environment and not potentially preventable (a not unreasonable interpretation, by the way), it turns out not to be such a bad first approximation at all. It’s actually not far off from what has been a fairly accepted estimate for quite a few years now, namely that between one third and one half of cancers are potentially preventable, implying that they are due to environmental causes that can be altered, such as smoking or diet. Given the level of uncertainty inherent in such estimates, even if you interpret Vogelstein and Tomasetti’s conclusion that two thirds of cancers are due to “bad luck,” their estimate of the percentage of cancers that are probably not preventable is definitely in the ballpark of commonly-accepted estimates, albeit at the lower end. Does that mean they’re on to something in concluding that stem cell replication over one’s lifetime primarily determines the “stochastic” component of cancer risk for each organ? That remains to be seen, but their preliminary finding makes sense, both from the perspective of producing a result that’s in the ballpark of what we already know based on epidemiology and being biologically plausible based on basic cancer biology." www.sciencebasedmedicine.org/is-cancer-due-mostly-to-bad-luck/ "What this study suggests is that at least 2/3 of all all cancers are due to random mutations - bad luck. The figure may be higher once breast and prostate cancers are included. Of the remaining third it is not clear how much is due to inherited genes vs lifestyle factors. The logic of the study is sound, in my opinion. The authors assume that lifestyle and genetic factors affect the risk of tissue-specific cancers, but not cancer in general. This study would miss, however, lifestyle or genetic factors that affected the risk of all cancers (regardless of tissue type) equally. One might argue, therefore, that it overestimates the role of random mutations, but that is only if you accept that there are universal risk factors out there."theness.com/neurologicablog/index.php/cancer-risk-largely-bad-luck/ "experts estimate that more than 4 in 10 cancer cases could be prevented by lifestyle change" Read more at www.cancerresearchuk.org/about-cancer/causes-of-cancer/can-cancer-be-prevented#KqpvkbgKRZC8EGDk.99www.cancerresearchuk.org/about-cancer/causes-of-cancer/can-cancer-be-prevented "The World Cancer Report, produced by the WHO's specialized cancer agency" ...

That's the kind of thing where I'd really suspect correlation over causation though. Vegans tend to eat better than the rest of the population even aside from their veganism, and are also more wealthy and have access to better healthcare. They tend to be more focused on personal health, too, which matters a lot. So this is the kind of thing where I'm not sure you can say "veganism reduces risk". Rather, I think it's more likely that "people with less risk are more likely to become vegans".
Absolutely. I've yet to see an obese vegan. Of course it can also be argued that being vegan reduces risk of becoming overweight. Which is good. In the end protein is protein, carbs are carbs, and fat is fat. Be vegan for ethical reasons, but there's nothing that makes getting nutrients from plants strictly better than from animal products.
@Joseph, I know this is an old thread I'm replying to, but while in some ways you're correct, I think you're missing some of the facts. There are components to foods other than what's printed on the nutritional label, and things like heme iron vs. non-heme iron have an effect on cancer, and animal-based foods appear to cause an increase in phthalate levels, which cause hormonal disruptions in both behavior and anatomy. Meat, eggs, and dairy are also sources of exogenous hormones themselves, and even a single glass of milk can cause an almost-immediate, measurable increase in a man's estrogen levels.
Hey HCT. I recently gave up smoking. I'm 4 weeks off right now. Obviously there's a lot of health benefits to this, and I'm already starting to feel them, but there are also some side effects beyond wanting to smoke that aren't talked about. Dry mouth, mouth ulcers, cough, etc. I feel like I was not properly informed of these things, and they worried me. When I found that these were "symptoms" of giving up smoking, I felt rather annoyed that I hadn't been told about these things. I was going to give up smoking anyway - I couldn't afford it as a college student, it was bad for my health and negatively impacted on my social relationships. What I want to know is - is this done on purpose? Are people not told about the possibly hardships of giving up smoking besides the withdrawl to avoid scaring them away? If not, why isn't it advertised clearly so people like me, quitting without going to my GP, know what they're getting into? I'm sure going to my GP would result in a more effective quit rate overall, but many people in my position, and I'd argue many smokers in general, cannot afford a visit to a GP just to be told how to give up smoking.
Obviously I'm not HCT but I did quit smoking about 5.5 years ago. You're right, there are a lot of things no one talks about. I didn't have a problem with ulcers and I never coughed up anything but I did get super gassy because, evidently, smoking affects your digestive system. Before I quit I had only had indigestion twice in my life, after I quit I get it regularly. My labito bascily stopped for two years after. People often say food tastes better after you quit, I found that to be an over exaggeration. But the worst thing for me (and I realize I'm in a minority here) I do not feel any healthier. Quite the contrary I've often though I felt healthier before I quit. I've also improved my diet since and despite that I've gained ~45 lbs.I don't regret quitting but when people do ask me about it I tell them I quit for the money, as we were spending a hefty amount on it. Still to this day when someone lights up close to me the smell is so good. You're 4 weeks in? I'm not gonna sugarcoat it, you have a long road a head. You're through the absolute worst of it, the first 72 hours, but the craving go on for a long while. But, it does get easier.
Congratulations on your decision to quit smoking! However it does not make sense for the health care field to not inform you about side effects after quitting smoking in hopes to keep you participating. You seem to forget that doctors and other health care professionals joined the practice to help others and assist in achieving a healthy lifestyle. After all, the tobacco companies would be the ones to scare you into quitting in hopes of making more profit, not the health care field. The small effects you were talking about such as dry mouth, mouth ulcers, cough etc. are all a small price to pay for overall better health, especially if you say the habit was interfering with your personal relationships. Also, these small side effects have also been shown to go away within a few weeks. Short lived impacts are much more forgiving than the long-term impact of smoking.
The amount of cell division that occurs in a lifetime can and does increase the chances of cancer. This is proven with how the older people get, the higher of chances they have for getting cancer comparing to the young. But of course not all cancer derives from the high repetition of mitosis in cells. The extrinsic factors of cancer and the four factors to be considered low risk aren't all that hard to apply yourself to. How taxing is it to put sunblock on or to exercise or to not smoke or to smoke less? Not that hard when you compare it to fighting off cancer. It is mind blowing to me how some people can be ignorant enough to say something like "well what are the chances I'll get cancer" as they puff on a newly lite cigarette. Obviously one person can't make it so they are invincible to cancer, but why wouldn't an individual attempt to be considered low risk and possibly avoid it and reduce their risk to it. Instead of watching a half hour of television, one can easily go for a half hour jog or walk. Even the slightest bit of exercise is beneficial. The fact that a nickname for cigarettes is 'cancer sticks' and smoking is an instance that causes someone to be at a high risk for cancer and people still smoke them is beyond me. It's as simple as finding a better substitute for alcohol and cigarettes or decreasing your intake. Exercising and decreasing obesity go hand in hand. Eat less, eat more healthier, and exercise at least a few hours a week can all help one become less obese. To become considered a low risk for cancer is manageable for anyone and everyone. This should be taken into consideration every single day of an individuals life. People don't realize how good they have it until they are diagnosed with cancer. Play it safe or even slightly safe to help yourself out in the future and save some suffering.
What is meant by not smoking being defined as 'never having smoked or having quit in the last five years'? This would mean someone who quit smoking six years ago wouldn't fit the definition of 'not smoking'. Surely 'never having smoked or having quit more than five years ago' would be a better definition.
Damn, I didn't catch that one. According to this, if you quit smoking more than 5 years ago, you've not quit in the last 5 years, nor have you never smoked.
I guess they probably wrote it thinking 'never having smoked or having quit in the last 5 years' means 'never having smoked, and also never having quit in the last 5 years'. Which is maybe a legitimate reading of it, but the sentence is ambiguous. 'Never having smoked nor having quit in the last 5 years' is completely unambiguous and would have expressed what they meant much better. This is why grammar is important.
It depends on the study parameters. Truly your criteria would be more comprehensive. But they might be studying people who quit recently compared to this who had never smoked. This makes a difference in study and control groups.
I've read that long term breastfeeding (breastfeeding til 2 years) massively lowers your chance at breast cancer IF you don't carry the BRAC mutation or have a family history of it. This is predicated on also being a non-smoker with low alcohol consumption. I'm curious if the benefit of long term breast feeding can reduce or at least delay the odds of getting breast cancer at a younger age and allow a woman to avoid a mastectomy at say 30 vs 45?
". . . They identified four domains that are often noted to be related to disease prevention: smoking, drinking, obesity, and exercise. They defined people who engaged in healthy levels of all of these activities as a 'low-risk' group." So... how much obesity activity is a health amount of obesity activity?
Replace the slide at 4:00 with this equivalent statement ... "Overall about 75% of cancer in women and 67% of cancer in men could not be prevented. Close to half of all cancer deaths could not be prevented in people as well. " So probably you can't prevent cancer but you could try. -Cheers!!
Natte Wasbeer It could be if your chance from death by cancer were large in the first place, say reducing the chance from 60% to 30% but if the chance were 2% reducing it to 1% may not be a huge change.
I don’t even pour facet water into my iron, let alone drink it! The iron alone tells you how much junk is in that stuff, by all the dirty brown water it steams up.
As a child, I've had a couple of quite severe sunburns. AFAIK, that greatly increases my chances for skin cancer. Is there anything to do to minimize risk for skin cancer? How much sun exposure is acceptable?
Any of them. Regardless of your weight you can get any cancer though certain ones can be less likely at a healthy weight. Granted I hope 18 bmi is healthy for you because it is rather low.
Since Michael Phelps had the marks on his back at the Olympics, I've been seeing a lot people sharing BS about fire cupping "therapy". What do you think the research tells us about this? I'd love to see a video!
There is some truth to it. When mass screenings for cancer occur there is a lot of it found and treated many of which, if left untreated, would not do any harm at all. There is an older video on this channel about it
Feeding infant girls a high animal protein diet, like the usual American diet, causes them to reach their menstrual cycle faster. Reaching your menstrual cycle faster increases your chance of getting breast and ovarian cancer. (The China study)
Many people believe that the contracture of cancer is out of their control, unlike something like heart disease where you can just change your diet, exercise, and quit smoking to get rid of heart disease. Both of these beliefs are wrong. Yes, heart disease is preventable but what isn’t preventable is your family history, age, and race. But people feel completely different about cancer, this belief was reinforced by a study published in ‘Science’ in January 2015. This attempted to explain why some tissues lead to cancer more often than others. They found a strong correlation between the number of times a cell divides over the course of a lifetime and the risk of developing cancer. In simpler words, this study argued that the more times we ask DNA to replicate, the more often something can go wrong. Some took this to mean that cancer is much more due to “bad luck” than other factors that people can control. Unfortunately, this simple explanation is not really what the study showed. For instance, its proven that lung cells divide quite rarely, and still account for a significant amount of cancer. And cells in the gastrointestinal tract divide all the time and account for many fewer cancers reported than in the lungs. Some cancers, like melanoma, were argued to be due to intrinsic factors, when we clearly know that extrinsic factors, such as too much sun exposure, are a major cause of that type of cancer. A more recent study published in ‘Nature.’ This study argues that there is a lot we can do to prevent cancer. Many studies have shown that environmental risk factors and exposures contribute greatly to many cancers. Such as diets related to colorectal cancer, alcohol and tobacco being related to esophageal cancer, HPV related to cervical cancer, too much sun being related to skin cancer, smoking related to lung cancer and Hepatitis C being related to liver cancer. Researchers at Jama Oncology sought to qualify how a healthy lifestyle might actually impact the risk of getting cancer. They identified four domains that are most often related to disease prevention: smoking, drinking, obesity and exercise. People who engage in healthy levels of all these activities are considered a “low risk” group. Then they are compared their risk of getting cancer to the people who were not in this group. They included two very-studied cohorts from the Nurses’ Health Study and the Health Professionals Follow-up Study, as well as national cancer statistics. When a group of men (46,000) and women (90,000) were classified into one of the two groups (low risk and high risk), 16531 women and 11,731 of the men fell into the low-risk group. Looking at these numbers is very surprising. There are way more people classified as high risk than those who are low risk.
: I believe that it is the human who creates the cancer that is created in the body. We as humans do not take care of our bodies the way that we should. This means eating a healthy balanced diet. We eat too many greasy and unhealthy foods and we have a habit of turning to quick and fast meals instead of taking our time to prepare a healthy meal that will nourish and fill our bodies. We do not exercise the way we should and I know everyone has schedules that they go by everyday but a thirty minute to an hour exercise would not hurt. It will improve health and decrease health risk. Many people are obese because they do not care about their health or they are concerned they just crave all the bad things that they know they should not eat but they eat it anyway. A way to help a situation like this is by eating small portions. I know that everyone will not go down that healthy trail but to decrease risk of cancer you can find fruits and veggies that you like a lot and eat more of that. Also it is okay to eat a few unhealthy things here and there it won’t kill you.
I reside in Seattle, I'm also in the low risk group. Is it better to use edibles or does smoking it not matter? (I did see the year ago video) Just looking to try it in a healthy way.
George Cataloni /shrug. Beats me. I don't understand the vast majority of cancer's risk factors. The way that he said it, it sounds like exercise is preventative regardless of BMI and vice-versa, but I haven't read the study itself so I'm partially talking out of my ass.
BMI pisses me off, every single time anyone talks about it. I realize that there were a lot of caveats in the BMI episode, and that on average it may really correlate with real risks, but when it's enshrined in public policy-as it is where I live-it gets abused to a crazy extent. I know that I'm a bit overweight, but BMI puts me solidly in the "obese" category, because I'm a big guy with large, long bones and big muscles. I'm tall, but not a beanpole. I'm clearly well outside the expectations BMI makes. I don't know what percentage of the population are similar BMI outliers, but the government here doesn't want to know that such a thing even exists. BMI needs to go.
Yup! Tobacco smoke no matter it is from the mainstream or side stream of a filtered cigarette, unfiltered cigarette, cigar, pipe, roll-your-own cigarette, hookah, cigarillo, etc. are carcinogenic and avoiding these exposures will shave off some cancer risk.
yes, but only in large quantities consistently for years, for example working at a Bar that allows Smoking for decades, or cohabitation with a heavy smoker. if you only pass by a smoker a few times a week on the street it's not something to worry too much about.
I really don't understand how the statistics are arrived for on things like 'Might have avoided getting the cancer vs most definitely would have gotten the cancer' especially when as far as I know one isn't guaranteed to have cancer from birth as such - since cancer mutations are mostly arbitrary...
If the rate of lung cancer is x in the high risk group and y in the low risk group, the difference is the group of people who would not have gotten cancer had they been in the low risk group. There's likely fancier math than this, but it points you in the direction of how you know how many more people got cancer in one group than the other. Knowing that doesn't tell you which high-risk person wouldn't have gotten cancer if they had been in the low risk group, only how many, percentages, etc.
I have a recurrent brain tumor (ependymoma in the pineal gland) it’s been treated 4 times with surgery, radiation, and finally chemo. I did expose myself to a considerable amount of EM radiation in my younger years in the form of excessive television, and video games. Could this have caused my cancer?
not a doctor, but TV and the like don't produce ionizing radiation which is the energy types of EM radiation that actually cause genetic damage. Otherwise, any heat or any light could be considered a danger. Sometimes you just get unlucky. I'm 38 and have stage 4 cancer of something I shouldn't have to screen for another 12 years, I have no high-risk behaviors, no family history or genetic defects, when talking with a genetic consultant about my behaviors and the results of genetic testing I'm literally less than one in a million case of bad luck, sometimes bad stuff just happens.
I feel your pain Garith. Cancer’s no fun, and the stroke of bad luck seems to brush over us more than others. Just lucky that way, I guess 😜 I wish you the best of luck with your diagnosis, and am here, if you want to send a message, or anything like that.
@@kevinmoore2501 Well, things could be worse, my first opinion was that I'd be dead a month ago max without treatment and gave me 2-3 years max with it, chemo only with no further plans. Dude even sent in a chaplain and hospice care to talk with me. I, of course, got a second opinion and am currently at a place that focuses on cancer and they seem more optimistic especially given my age. Currently on round 14 of chemo treatments with plans to evolve around how the treatments progress as I've already had my chemo treatments changed as new data came in. I think I'm in about the best place I could be given the initial bad luck so I feel pretty fortunate. The offer goes to you as well if you'd like someone to talk with, though you sound like you're well versed in this rodeo already.
I would tend to agree, Garith. This is my 4th recurrence of cancer. The first two times, I had surgery, which permanently handicapped me. Because of the location of my cancer (tumor), however, the only real handicap, which I’m working to overcome is my loss of balance, due to my cerebellum being removed to allow more buildup, and drainage of chronic hydrocephalus which I have now. My team, god bless them, have done so much for me from surgery to radiation, months of therapy, etc. They really rebuilt me, and I’m forever appreciative, and indebted to all of them for that.
I love that he made a video about this because cancer is definitely a rising problem in America today. It is a very scary topic because a lot of the times cancer is uncontrollable and can effect any one at any time. Obviously if you excessively smoke or drink then you are giving yourself a higher risk of developing cancer in your lungs or liver. Yes, there are many cases where people that have never smoked or drank in their life will develop cancer in those areas and it is uncontrollable. However if you do participate in those activities then the consumer should understand that they are at a much higher risk and a very likely to get it compared to others. I knew that being healthy and taking precautions can help avoid getting most diseases but I was not completely aware that being healthy can even prevent some cancers. This does make me feel a little more at ease knowing that I do have some control over this disease because most of the cancers do happen spontaneously and without any reason or any way to prevent it from that person. Cancer has effected me in many ways in my life and it is great to see that I can control it to an extent and that I can have some say in this disease prevention.
Not smoking is never having smoking or having quit 5 years ago, but in my case, as a person who has not habit of smoking, but smokes in social situations (about twice a month, or less), and smokes a small amount of cigarettes, am I a smoker or a non-smoker? (Ps.: I'm not a teenager or a college student, who is in process of acquiring the addiction)
By definition you're a "moderate smoker" . I'm not sure if your risks are any higher than someone who lives in a downtown core with lots of car exhaust fumes though. I don't "smoke" but my lungs are probably pretty bad. xD
"social smoking" is how most people start smoking. SO over the next few years you might become a full blown smoker, but your still in the moderate category now.
knowing is not enough, If we want a healthy population, we need to have more engaging tactics. a great example was the Y program with prediabetes patients. As per exercise, great ideas are parks with public exercise machines (popular in eg SKorea, some parts of Europe, afaik).. but what else? we need to stop talking AT the people who then just nod nod and leave.
I feel like the more you worry about it the more likely you are to get cancer. I know this isn't true. Maybe it's because I'm still young but I just don't worry about cancer whatsoever.
I do believe that many cancers can be preventable. Like skin cancer because you should wear sunscreen when out in the sun, even though I sometimes do not or I wear tanning lotion and not being out in the sun for too long will help with not getting skin cancer. Lung cancer can be preventable if you do not smoke or if you do then should quit smoking to help prevent it. There are some cancers though that cannot be preventable like breast cancer and sometimes cancers that run through your family and have been in your family in the past. I agree with him when he says that cancer is the "silent killer." It really is because many people never know they have cancer until it is too late because some people do not have symptoms for cancer or the cancer does not effect them till it has been in their body for a while.
Being a survivor of hodgkins lymphoma not once but twice, I believe cancer is 100% unbiased. Do people who have never gone out in the sun get skin cancer? Yes. Do those who have never smoked a day in their life get lung cancer? Yes. Of course there are those more susceptible to the "cancer genes" whether that be from heredity or having already had cancer. But whether you try to prevent it or not I think getting cancer is inevitable to those who get it. Some cancers cannot be traced to how those who have it get it. Not hereditary or lifestyle choices its just the luck of the draw. They say mine could have come about from having mononucleosis but I know many if not hundreds that have had mononucleosis and did not get cancer. I under what he is saying, how there are causes of some cancers but those also don't have a strict guideline. Some people smoke there whole lives and never get lick of lung cancer. Then there are those who tan every single day in a tanning bed, tan outside and never get skin cancer or any type of cancer. Cancer is unbiased, it does not matter your age, race, morals, background, family life or lifestyle. If you're "meant to get cancer" you will.
I first want to say that I offer my condolences, as to having been through hodgkins lymphoma twice, and wish you good luck in the future. You stated that cancer is 100% unbiased, and I have to respectfully disagree with you. I understand where you are coming from, as that I agree that there are times when people will do everything to put them at higher risks, and still never get cancer throughout their life. But, even though a majority of the time people develop cancer at random and couldn't have prevented it, I wouldn't go as far to say that it is 100% unbiased as that there are often times as well where the patient could have prevented it according to their lifestyle. There is also the hereditary factor, where if a certain cancer is known to have run in the family, the individual can possibly have a better chance of the particular diagnosis, and that is just a fact. Even though each case, and person, and disease is different, there's just often times when the hereditary factor can be reasoning as to diagnosis.
"Close to half of cancer deaths could be have been prevented". And more than half couldn't have been, which is why chance plays an important, seemingly more important, role?

Cancer is one of those terms that everyone knows, and most people have a story that pops in to their mind when they hear the term. Whether it be about their own battle with cancer or a battle they experienced second hand through a friend or family member, almost everyone has an experience with cancer. I myself have never not been surrounded by it, even from a young age. In my own personal family history, I have numerous different types of cancer ranging both on my father and mother’s side. Cancer, for me, is almost an inevitable fate. That is one of the reasons why this particular video really stuck out to me. How can we, as mere mortals, prevent something so much more destructive than ourselves? The idea of being able to prevent cancer is something that people have thought about for decades. Cancer prevention is an attainable thing to a certain extent. A healthy diet and lifestyle can greatly impact your risk of getting cancer. Whether it be eating healthier or staying out of the sun during the summer, we all know the common preventative measures taken in order to reduce our risk of getting one of the many different forms of cancer. It has recently been discussed that these “preventative measures” are actually extremely underestimated in their abilities to help prevent it though. But can we really prevent cancer in all of its entirety? I mean look at my situation, I am surrounded by cancer on both sides of my family tree. Genetically speaking, the probability that I will get some form of cancer at some point in my life is extremely high. So does that mean I shouldn’t follow these preventative steps because, even if I carefully follow all of the preventive measures that I possibly can, the likelihood of me getting cancer is basically 99.9%? From a girl who has accepted that I will have cancer at some point in my life I still plan on taking any preventative steps that I can because, well, why not? Maybe I will be in the 0.1% that magically, against all odds, doesn’t get cancer because I did everything I could to prevent it. And maybe if all of society thought this way about cancer, and other health issues, the statistics could drop and maybe then we wouldn’t all have a “cancer story” that pops into our heads when we hear that word.
Omg, this has been 5 years ago. But I just wanna say that I totally agreed with your mindset! Even tho I'm in the low risk group, I have an anxiety about cancer. Anyway, how is it going now for you? I hope you are in a healthy condition!
Just read about the 5 biological (nature law) and you know how to prevent cancer.
Drink one glass of lemon juice without adding water for a month....it can cure if the cancer is stage 1
we got a chatter box…
That's amazing you have a strong and positive mindset and you are doing right job by thinking like that
That's a good thing
The thing I hate most about all this cancer prevention stuff that has gone a bit crazy and produced zealots that think they can avoid cancer by doing everything right is that sometimes, cancer is totally random and that sucks. My mom was 46 when she was diagnosed with stage 2-3 (they couldn't agree on the number) breast cancer. So many people would quiz her on all this prevention stuff until they started getting into the strange stuff like using paraben based soap and eating sugar to try to find a reason it happened to her and wouldn't happen to them. She wasn't a smoker, overweight, tall, inactive, immunocompromised, or from a family prone to cancer, and young. It was random misfortune and some people just refuse to accept that it could happen to them even if they did everything "right".
About 3 in 5 cases are not preventable. So, unfortunately, many people do the right things and still get cancer. Sorry about that.
Since I made this comment my mom got cancer again and it turns out that it's genetic, so definitely not something that different soap could prevent.
@@AbbeyB77 i feel bad for your mom. Hope she and you are in peace..
And The fact that you came after 4yr is awesome..
@@AbbeyB77 I'm really sorry for you and your mother. How is she now?
I just wanted to say I love your channel! I'm going to university to study statistics and biology, and your focusing about statistical trials in medicine really excites me about the future career I want to have. It also shows everyone how important well designed studies are in medicine, and how bad studies can truly flip findings on their head. Thanks for a great channel!
Are you a doctor now?
I'm in the low risk group! Woo! But I'm planning on becoming a health professional.. so I'll probably be so stressed I stop exercising and start eating. I recently started cycling to work and it rules. I save 30 minutes a day, I get exercise, and I enjoy it.
Nice to see that you try to practice what you preach :D
walking to work is better (more time), but cycling sure saves a ton of time
Cycling seems more vigorous to me, unless you jog to work, of course.
***** that depends on how fast you cycle and how far you are from work. I can cycle leisurely, get an aerobic workout, cycle quickly, get an anerobic workout. I normally get my heart rate up to 120, which is just what I need. :) It is 40 minutes a day of proper exercise, for free.
Jogging does permanent damage to your knees, cycling is GOOD for your knees. (unless your seat is too low, you shouldn't be able to touch the ground with both feet while sitting on the seat, for a start)
If you want to spend as much time cycling as you would walking you can just take the long way to work, of course, and walking to work was only ever light exercise for me, it didn't allow me to hit the minimum.
The
I'm three out of the four. I'm exercising more recently, so hopefully my weight will go down.
I never thought that a video on cancer could cheer me up.
I am in the low risk group as I don't drink or smoke, don't take dangerous drugs, exercise every day and maintain a healthy weight. The one thing that does bother me though is vehicle fumes and their negative effect on health and cancer risk from those, as its often hard to avoid vehicles these days unless you live in the middle of a wilderness somewhere away from most vehicles. I watched a program on TV earlier this year and have also read studies that showed that, even if your inside a car, you can still be exposed to lots of harmful toxins and driving in an electric car was better for your health than a car that used fossil fuels. Could you make a video on vehicle pollution and health?
Love the video! Could you do a video on menopause for my mum haha. I think a lot of women get confused on the advice given to them by other women and on the Internet.
yup, we really need this one!
Agreed!
This! HCT listen up! Y'all should really do this. :D

We know that the risk of cancers like lung cancer or skin cancer are increased by smoking or excessive exposure to the sun, but there is still so much about cancer that we haven't yet figured out. I agree with what the video say about being careful with how much weight we put on lifestyle causes of cancer. The idea that most cancer is preventable should help influence one's lifestyle choices hopefully, as long as it doesn't get to the point of not treating cancer that could have been prevented with the same diligence that we treat less avoidable cancers. I believe that this is one of those 'slippery slope' situations that we should try and avoid. However, it is also important to spread awareness about ways we can live a more "low-risk" lifestyle.
Hi Krystal, thank you for your comment! I agree with a lot of what you have to say. I think if people know how they can reduce their chances of getting cancer can lead to more "low-risk" lifestyles as you had mentioned, which in my opinion are just overall healthier with maybe a few exceptions. As someone that works in healthcare, it is important to make sure your patients understand the risk that come with certain lifestyle choices. It is our responsibility to spread the awareness of how certain lifestyle choices can increase or decrease our risk of getting cancer. One "biggy" is obviously smoking. We, in the end, have the ultimate decision about the lifestyle choices that we make and the consequences that come with them, good or bad. Promoting this awareness should not change how we screen or treat cancer. Screening should never be replaced with "healthy" lifestyle choices. There are many people out there that lived extremely healthy lifestyles but still
ended up with cancer. Their lives would have most likely been cut short by runaway cancer if it weren't for certain screening tests done that ended up catching the cancer. If we can prevent it, it is best to catch it as early as possible.
I think the best way to prevent cancer and its consequences is by doing all we can do prevent it by our lifestyle choices and then screening tests and other labs to stop it in its early stages! Thanks for your comment!
I appreciate the work you're doing in making these videos!

+Healthcare Triage Hey HCT! I've enjoyed watching your videos for a long time (really like how informative and evidence based they are). Would you ever consider doing other videos similar to this one about other illnesses eg. "You Can Do a Lot to Prevent Some Forms of Dementia".
Also, if you had any advice or know of any studies that might provide us viewers with any practical guidance over what we can do to prevent or lessen the risk of developing such conditions (past eating, sleeping or exercising right and wearing sun cream), I have a hunch people would be interested in tuning in to learn about that. Just a thought. Thanks again for all the great content! :D
I would love to see a series like that. It would be relevant to a lot more viewers who aren't into the statistics and policies as much.
Some Curiosities +
Many people have a misconception about cancer, and that if you get cancer you just have "bad luck" and cannot prevent it. People often talk about cancer being one of their biggest fear but do they do anything to attempt to prevent cancer? Fitting in the four categories of the low-risk of cancer isn't anything too extreme. As discussed in the video the four requirements are: never smoking or have quit for over 5 years, moderately consumption of alcohol which was 1 drink or less per day for women and 2 drinks or less for men, having a BMI between 18.5 and 27.5, and completing 150 minutes of moderate activity or 75 minutes of strenuous activity. These requirements aren't as difficult as most people like to assume, and are quite reasonable. I think the problem is that people like to make up too many excuses for trying to meet these requirements. Some many argue that they don't have enough time to complete 150 minutes a week of moderate exercise but that breaks down to less than 30 minutes a day of exercise. That may seem like a lot, but think of how many minutes you spend watching tv, or scrolling through Facebook a day. Also, you don't have to be "skinny" to fit into the low-risk group either. The BMI for overweight as mentioned has a cut off of 25, whereas the requirement says no more than 27.5 BMI which means you just cannot be obese which is 30 BMI. Not smoking should be a reasonable requirement, as well as the moderate drinking. This does not say that you have to refrain from drinking, but rather drink a less amount. I think if more people knew about these requirements that they would try to meet them before they think it is impossible to quit drinking, or workout throughout the week.
The next point that stood out in this video is that although meeting those four requirements that were discussed, it does not completely eliminate your risk for cancer. It was stated that overall 25% of cancer in women and 33% of cancer in men could be prevented. That means that about 75% of cancer in women and 67% of cancer in men cannot be prevented. There is still a higher percentage of cancer that cannot be prevented but you cannot look at it from the negative viewpoint. These percentages do not mean don't try to prevent cancer. It is still beneficial to attempt to meet these four requirements not only to prevent cancer but to also prevent other health issues by living a healthier life.
I learned from the anime, Cells At Work, that laughter helps reduce cancer, because laughter energizes Natural Killer cells.
have you seen the 2nd season?
We all get cancerous cells at some point, but the immune system usually recognizes it and kills it before it gets out of hand. What we call cancer is actually just too much cancer... we all get cancer all the time.
(a book called Genome and a book called Why we get Sick.. those are my sources)
I did a course on exercise and.. wow.. do we need to exercise
Also, being sedentary for long periods is bad, even if you exercise afterwards. Get up and move around every half hour!
Can stop feeding cancerous cells with a crappy diet. Every study on exercise says we need to do it more.. 30 mins/day is better than none, 45 better than 30, 90 better than 45.. they've not found an upper bound of diminishing returns...
+Shawn I'm pretty sure 24hours/day is the upper limit
Hi Dr. Carroll,
I love watching your Healthcare Triage segments, I think they do a wonderful job at informing the public on relevant health related news of today. I am curious if you'd do a video on Physician Suicide and your thoughts on why it happens and how society might address this issue.
Thank you!
Some people think that cancer is the greatest cause of death when really, it is cardiovascular disease. As mentioned in the video, some cancers are preventable while others are not. I think it is important that people know how preventable some cancers can be, such as skin cancer. In the summer, everyone likes to be tan and have bronze looking skin. But do they really consider how harmful it can be to your body? A lot of people will risk getting skin cancer from UV radiation when they want to look tan by either sitting outside in the sunlight or even going to a tanning salon. Something as simple as wearing sunscreen can make a huge difference on someone. I know I have a risk of getting cancer because my dad had been diagnosed with it. Not only do I know that I have a chance of getting cancer, but I also know that it can be prevented. Eating healthy and exercising is an effective way to prevent some cancers and since most people are worried that they will be diagnosed with cancer, everyone should be informed that sometimes those simple steps can prevent such a life threatening situation. Unfortunately, some cancers cannot be prevented as easily because they are inherited. Just because some cancers can be inherited, doesn’t mean that people shouldn’t try the steps to prevent it anyway. Cancer is such a scary thing to witness whether it be first hand, or second hand through a family member or friend. Anyone can get cancer, but anyone can also help reduce the risk of getting cancer. With the help of chemotherapy and radiation treatment, some people are cured of cancer. The cure for cancer has been being tested and experimented for so long and sometimes doesn’t always work. Instead of waiting to see if they will be diagnosed with cancer, people should take the advice and use the steps to help reduce your risk of getting cancer.
Didn't say much about breast cancer. In fact, it seems the only thing ever given was to perform self - breast exams and get mammograms. One presentation that was considered to make me low risk was fibrocystic breast disorder (Lumpy - bumpy breasts).
But I got breast cancer in 2016 as a 52-year - old. And my self - examinations didn't seem to tell me anything till one day I woke up on my belly, adjusted my boobs for comfort, and found a hazel nut - sized lump clearly on the outside perimeter of my breast, 12-o'clock high, if you will.
I learned so much about cancer during my treatment, and I found when I was in the grocery buying produce, I had cravings. I would search in Google regarding each food and cancer, and in every case, I found that there were chemicals in these fruits and veggies were being studied as candidates for creating new chemo medicines.
I didn't stop chemo and try to use only foods to cure it. If you can detect cancer, it's too late for that. But the cravings were fascinating to me. I'm a"kitchen sink" person: I'll throw everything at a problem, even the kitchen sink if I think it would help. So I followed my cravings.
Something I DIDN'T crave, strangely, was citrus fruits. Many cancer patients protest that oranges don't taste right. And I think people want to eat them because of vitamin C. That's all well and good, but vitamin C is in all fresh fruits AND vegetables.
I wanted cantaloupe, broccoli, cauliflower, rutabaga, bell peppers, grapes (especially black), blueberries, soybeans (edamame), tree nuts and peanuts, cabbage, beets, chicken AND pork (I wanted chicken soup so bad). Celery (I don't eat it most times) black beans and great northern beans, apples and Romaine lettuce, peas, potatoes, Braunschweiger, Cream of Wheat made with milk, eggs, and others. I did not prevent myself from eating meat, and my brother in law would get me a Rally's (Checkers) Baconzilla with 2 beef patties and bacon when he'd shop for me (and then made sure I ate it).
Eat fruits and veggies period. These chemicals that are being studied for chemotherapy treatment are available to everyone. The truth is, there is always one cell or another going rogue in your body, and that's what the immune system takes care of. When you eat the whole food, you get the benefit of whatever chemicals we don't know about, yet, and that can give us a benefit beyond what science knows yet.
most cancers are, in fact, due to stochastic mutations = bad luck. the study in question gets this right. they estimate about 1/3 of cancers are due to extrinsic factors, which is congruent with other estimates. 70-90% from the nature article significantly exceeds most estimates.
"If you interpret Vogelstein’s estimate the way it’s been represented in
the press and by Vogelstein, as representing the percentage of cancers
that are due primarily to “chance” and thus not related to environment
and not potentially preventable (a not unreasonable interpretation, by
the way), it turns out not to be such a bad first approximation at all.
It’s actually not far off from what has been a fairly accepted estimate
for quite a few years now, namely that between one third and one half of cancers are potentially preventable,
implying that they are due to environmental causes that can be altered,
such as smoking or diet. Given the level of uncertainty inherent in
such estimates, even if you interpret Vogelstein and Tomasetti’s
conclusion that two thirds of cancers are due to “bad luck,” their
estimate of the percentage of cancers that are probably not preventable
is definitely in the ballpark of commonly-accepted estimates, albeit at
the lower end. Does that mean they’re on to something in concluding that
stem cell replication over one’s lifetime primarily determines the
“stochastic” component of cancer risk for each organ? That remains to be
seen, but their preliminary finding makes sense, both from the
perspective of producing a result that’s in the ballpark of what we
already know based on epidemiology and being biologically plausible
based on basic cancer biology."
www.sciencebasedmedicine.org/is-cancer-due-mostly-to-bad-luck/
"What this study suggests is that at least 2/3 of all all cancers are
due to random mutations - bad luck. The figure may be higher once breast
and prostate cancers are included. Of the remaining third it is not
clear how much is due to inherited genes vs lifestyle factors.
The logic of the study is sound, in my opinion. The authors assume
that lifestyle and genetic factors affect the risk of tissue-specific
cancers, but not cancer in general. This study would miss, however,
lifestyle or genetic factors that affected the risk of all cancers
(regardless of tissue type) equally. One might argue, therefore, that it
overestimates the role of random mutations, but that is only if you
accept that there are universal risk factors out there."theness.com/neurologicablog/index.php/cancer-risk-largely-bad-luck/

Such a shocking news😢
There are studies that show that veganism has a strong cancer prevention effect across the board, with many different types of cancer.
That's the kind of thing where I'd really suspect correlation over causation though. Vegans tend to eat better than the rest of the population even aside from their veganism, and are also more wealthy and have access to better healthcare. They tend to be more focused on personal health, too, which matters a lot.
So this is the kind of thing where I'm not sure you can say "veganism reduces risk". Rather, I think it's more likely that "people with less risk are more likely to become vegans".
Citations? I'm asking out of true curiosity
Absolutely. I've yet to see an obese vegan. Of course it can also be argued that being vegan reduces risk of becoming overweight. Which is good.
In the end protein is protein, carbs are carbs, and fat is fat. Be vegan for ethical reasons, but there's nothing that makes getting nutrients from plants strictly better than from animal products.
@Joseph, I know this is an old thread I'm replying to, but while in some ways you're correct, I think you're missing some of the facts. There are components to foods other than what's printed on the nutritional label, and things like heme iron vs. non-heme iron have an effect on cancer, and animal-based foods appear to cause an increase in phthalate levels, which cause hormonal disruptions in both behavior and anatomy. Meat, eggs, and dairy are also sources of exogenous hormones themselves, and even a single glass of milk can cause an almost-immediate, measurable increase in a man's estrogen levels.
Best way to avoid cancer is to fast a few times a year for at least 7 days.
Hey HCT. I recently gave up smoking. I'm 4 weeks off right now. Obviously there's a lot of health benefits to this, and I'm already starting to feel them, but there are also some side effects beyond wanting to smoke that aren't talked about. Dry mouth, mouth ulcers, cough, etc. I feel like I was not properly informed of these things, and they worried me. When I found that these were "symptoms" of giving up smoking, I felt rather annoyed that I hadn't been told about these things. I was going to give up smoking anyway - I couldn't afford it as a college student, it was bad for my health and negatively impacted on my social relationships. What I want to know is - is this done on purpose? Are people not told about the possibly hardships of giving up smoking besides the withdrawl to avoid scaring them away? If not, why isn't it advertised clearly so people like me, quitting without going to my GP, know what they're getting into? I'm sure going to my GP would result in a more effective quit rate overall, but many people in my position, and I'd argue many smokers in general, cannot afford a visit to a GP just to be told how to give up smoking.
Obviously I'm not HCT but I did quit smoking about 5.5 years ago. You're right, there are a lot of things no one talks about. I didn't have a problem with ulcers and I never coughed up anything but I did get super gassy because, evidently, smoking affects your digestive system. Before I quit I had only had indigestion twice in my life, after I quit I get it regularly. My labito bascily stopped for two years after. People often say food tastes better after you quit, I found that to be an over exaggeration. But the worst thing for me (and I realize I'm in a minority here) I do not feel any healthier. Quite the contrary I've often though I felt healthier before I quit. I've also improved my diet since and despite that I've gained ~45 lbs.I don't regret quitting but when people do ask me about it I tell them I quit for the money, as we were spending a hefty amount on it. Still to this day when someone lights up close to me the smell is so good. You're 4 weeks in? I'm not gonna sugarcoat it, you have a long road a head. You're through the absolute worst of it, the first 72 hours, but the craving go on for a long while. But, it does get easier.
Congratulations on your decision to quit smoking! However it does not make sense for the health care field to not inform you about side effects after quitting smoking in hopes to keep you participating. You seem to forget that doctors and other health care professionals joined the practice to help others and assist in achieving a healthy lifestyle. After all, the tobacco companies would be the ones to scare you into quitting in hopes of making more profit, not the health care field. The small effects you were talking about such as dry mouth, mouth ulcers, cough etc. are all a small price to pay for overall better health, especially if you say the habit was interfering with your personal relationships. Also, these small side effects have also been shown to go away within a few weeks. Short lived impacts are much more forgiving than the long-term impact of smoking.
A lot of cancer is because of what we eat and how we work the things we are around the substances that man has made a lot goes into it
The amount of cell division that occurs in a lifetime can and does increase the chances of cancer. This is proven with how the older people get, the higher of chances they have for getting cancer comparing to the young. But of course not all cancer derives from the high repetition of mitosis in cells. The extrinsic factors of cancer and the four factors to be considered low risk aren't all that hard to apply yourself to. How taxing is it to put sunblock on or to exercise or to not smoke or to smoke less? Not that hard when you compare it to fighting off cancer. It is mind blowing to me how some people can be ignorant enough to say something like "well what are the chances I'll get cancer" as they puff on a newly lite cigarette. Obviously one person can't make it so they are invincible to cancer, but why wouldn't an individual attempt to be considered low risk and possibly avoid it and reduce their risk to it. Instead of watching a half hour of television, one can easily go for a half hour jog or walk. Even the slightest bit of exercise is beneficial. The fact that a nickname for cigarettes is 'cancer sticks' and smoking is an instance that causes someone to be at a high risk for cancer and people still smoke them is beyond me. It's as simple as finding a better substitute for alcohol and cigarettes or decreasing your intake. Exercising and decreasing obesity go hand in hand. Eat less, eat more healthier, and exercise at least a few hours a week can all help one become less obese. To become considered a low risk for cancer is manageable for anyone and everyone. This should be taken into consideration every single day of an individuals life. People don't realize how good they have it until they are diagnosed with cancer. Play it safe or even slightly safe to help yourself out in the future and save some suffering.
What is meant by not smoking being defined as 'never having smoked or having quit in the last five years'? This would mean someone who quit smoking six years ago wouldn't fit the definition of 'not smoking'.
Surely 'never having smoked or having quit more than five years ago' would be a better definition.
I thought that was what it said.
Ya, they meant 5+ years counts as non-smoking.
Damn, I didn't catch that one. According to this, if you quit smoking more than 5 years ago, you've not quit in the last 5 years, nor have you never smoked.
I guess they probably wrote it thinking 'never having smoked or having quit in the last 5 years' means 'never having smoked, and also never having quit in the last 5 years'. Which is maybe a legitimate reading of it, but the sentence is ambiguous.
'Never having smoked nor having quit in the last 5 years' is completely unambiguous and would have expressed what they meant much better. This is why grammar is important.
It depends on the study parameters. Truly your criteria would be more comprehensive. But they might be studying people who quit recently compared to this who had never smoked. This makes a difference in study and control groups.
I've read that long term breastfeeding (breastfeeding til 2 years) massively lowers your chance at breast cancer IF you don't carry the BRAC mutation or have a family history of it. This is predicated on also being a non-smoker with low alcohol consumption. I'm curious if the benefit of long term breast feeding can reduce or at least delay the odds of getting breast cancer at a younger age and allow a woman to avoid a mastectomy at say 30 vs 45?
". . . They identified four domains that are often noted to be related to disease prevention: smoking, drinking, obesity, and exercise. They defined people who engaged in healthy levels of all of these activities as a 'low-risk' group."
So... how much obesity activity is a health amount of obesity activity?
Replace the slide at 4:00 with this equivalent statement ...
"Overall about 75% of cancer in women and 67% of cancer in men could not be prevented. Close to half of all cancer deaths could not be prevented in people as well. "
So probably you can't prevent cancer but you could try.
-Cheers!!
Natte Wasbeer It could be if your chance from death by cancer were large in the first place, say reducing the chance from 60% to 30% but if the chance were 2% reducing it to 1% may not be a huge change.
Would you do a video on drinking tap water vs filtered water (ie: faucet water filter, filtered water bottles etc..) Thanks.
I don’t even pour facet water into my iron, let alone drink it! The iron alone tells you how much junk is in that stuff, by all the dirty brown water it steams up.
As a child, I've had a couple of quite severe sunburns. AFAIK, that greatly increases my chances for skin cancer. Is there anything to do to minimize risk for skin cancer? How much sun exposure is acceptable?
SUNSCREEN!
I'm in the same group. I wear sunscreen, but sometimes I look at all the freckles on my arms and wonder if I've already done to much damage.
30 minutes sun light is good for health and more than that it's dangerous
What would be the potential cancers one could get if they're under a bmi of 18/18.5?
Any of them. Regardless of your weight you can get any cancer though certain ones can be less likely at a healthy weight. Granted I hope 18 bmi is healthy for you because it is rather low.
Since Michael Phelps had the marks on his back at the Olympics, I've been seeing a lot people sharing BS about fire cupping "therapy". What do you think the research tells us about this? I'd love to see a video!
Thanks Sam!
how to prevent cancer: never go to the doctor so they never tell you you have cancer.
There is some truth to it. When mass screenings for cancer occur there is a lot of it found and treated many of which, if left untreated, would not do any harm at all. There is an older video on this channel about it
Feeding infant girls a high animal protein diet, like the usual American diet, causes them to reach their menstrual cycle faster. Reaching your menstrual cycle faster increases your chance of getting breast and ovarian cancer. (The China study)
Many people believe that the contracture of cancer is out of their control, unlike something like heart disease where you can just change your diet, exercise, and quit smoking to get rid of heart disease. Both of these beliefs are wrong. Yes, heart disease is preventable but what isn’t preventable is your family history, age, and race. But people feel completely different about cancer, this belief was reinforced by a study published in ‘Science’ in January 2015. This attempted to explain why some tissues lead to cancer more often than others. They found a strong correlation between the number of times a cell divides over the course of a lifetime and the risk of developing cancer. In simpler words, this study argued that the more times we ask DNA to replicate, the more often something can go wrong. Some took this to mean that cancer is much more due to “bad luck” than other factors that people can control. Unfortunately, this simple explanation is not really what the study showed. For instance, its proven that lung cells divide quite rarely, and still account for a significant amount of cancer. And cells in the gastrointestinal tract divide all the time and account for many fewer cancers reported than in the lungs. Some cancers, like melanoma, were argued to be due to intrinsic factors, when we clearly know that extrinsic factors, such as too much sun exposure, are a major cause of that type of cancer.
A more recent study published in ‘Nature.’ This study argues that there is a lot we can do to prevent cancer. Many studies have shown that environmental risk factors and exposures contribute greatly to many cancers. Such as diets related to colorectal cancer, alcohol and tobacco being related to esophageal cancer, HPV related to cervical cancer, too much sun being related to skin cancer, smoking related to lung cancer and Hepatitis C being related to liver cancer. Researchers at Jama Oncology sought to qualify how a healthy lifestyle might actually impact the risk of getting cancer. They identified four domains that are most often related to disease prevention: smoking, drinking, obesity and exercise. People who engage in healthy levels of all these activities are considered a “low risk” group. Then they are compared their risk of getting cancer to the people who were not in this group. They included two very-studied cohorts from the Nurses’ Health Study and the Health Professionals Follow-up Study, as well as national cancer statistics. When a group of men (46,000) and women (90,000) were classified into one of the two groups (low risk and high risk), 16531 women and 11,731 of the men fell into the low-risk group. Looking at these numbers is very surprising. There are way more people classified as high risk than those who are low risk.
: I believe that it is the human who creates the cancer that is created in the body. We as humans do not take care of our bodies the way that we should. This means eating a healthy balanced diet. We eat too many greasy and unhealthy foods and we have a habit of turning to quick and fast meals instead of taking our time to prepare a healthy meal that will nourish and fill our bodies. We do not exercise the way we should and I know everyone has schedules that they go by everyday but a thirty minute to an hour exercise would not hurt. It will improve health and decrease health risk. Many people are obese because they do not care about their health or they are concerned they just crave all the bad things that they know they should not eat but they eat it anyway. A way to help a situation like this is by eating small portions. I know that everyone will not go down that healthy trail but to decrease risk of cancer you can find fruits and veggies that you like a lot and eat more of that. Also it is okay to eat a few unhealthy things here and there it won’t kill you.
I reside in Seattle, I'm also in the low risk group.
Is it better to use edibles or does smoking it not matter? (I did see the year ago video)
Just looking to try it in a healthy way.
your voice soothes me :3 thanks for the video!
It seems like it ended abruptly.
I'm curious how exercise reduces the risk of cancer. BMI is already considered a factor.
Exercise does surprisingly little to reduce BMI. HCT did a video on this already, actually.
John Harvey I've seen it. Diet is more important, but at least exercise is related. Exercise affecting cell division, though?
George Cataloni
/shrug. Beats me. I don't understand the vast majority of cancer's risk factors. The way that he said it, it sounds like exercise is preventative regardless of BMI and vice-versa, but I haven't read the study itself so I'm partially talking out of my ass.
I have been exposed through a lot Ct scans at least 6 in the last 5 years. How can I reduce my chances after exposure? Please help. 🥺
is it get Cancer and it will gone when your Body Healthy or something?
Great Video! 👍🏾
Damn.....just finished my 5th glass of wine!
BMI pisses me off, every single time anyone talks about it.
I realize that there were a lot of caveats in the BMI episode, and that on average it may really correlate with real risks, but when it's enshrined in public policy-as it is where I live-it gets abused to a crazy extent.
I know that I'm a bit overweight, but BMI puts me solidly in the "obese" category, because I'm a big guy with large, long bones and big muscles. I'm tall, but not a beanpole. I'm clearly well outside the expectations BMI makes.
I don't know what percentage of the population are similar BMI outliers, but the government here doesn't want to know that such a thing even exists.
BMI needs to go.
I thought heart disease or high blood pressure is called the silent death
No comments on the the "China Study"?
MisticalOnEdg +
We learned about this study during lectures today :D
Anyone notice that HCT is getting fewer and fewer views lately?
Could second hand smoke count as smoking?
Yup! Tobacco smoke no matter it is from the mainstream or side stream of a filtered cigarette, unfiltered cigarette, cigar, pipe, roll-your-own cigarette, hookah, cigarillo, etc. are carcinogenic and avoiding these exposures will shave off some cancer risk.
yes, but only in large quantities consistently for years, for example working at a Bar that allows Smoking for decades, or cohabitation with a heavy smoker.
if you only pass by a smoker a few times a week on the street it's not something to worry too much about.
I really don't understand how the statistics are arrived for on things like 'Might have avoided getting the cancer vs most definitely would have gotten the cancer' especially when as far as I know one isn't guaranteed to have cancer from birth as such - since cancer mutations are mostly arbitrary...
If the rate of lung cancer is x in the high risk group and y in the low risk group, the difference is the group of people who would not have gotten cancer had they been in the low risk group. There's likely fancier math than this, but it points you in the direction of how you know how many more people got cancer in one group than the other. Knowing that doesn't tell you which high-risk person wouldn't have gotten cancer if they had been in the low risk group, only how many, percentages, etc.
Appreciate your work
5:00 that does not seem like a lot to ask for me, how fucking hard should it be to control what goes in your body and what you do with your body.
can we have the Thought Bubble for HCT too? I love this channel so much but I don't like it when Aaron just reads what's on the screen :))
I was absolutely delighted with the immediate cancer healing I got through Dr gboya on RUclips. Keep saving lives doctor ,👍
What were the risk reductions in pancreatic cancer you discussed?
4:27 feels relevant to Covid today.
I have a recurrent brain tumor (ependymoma in the pineal gland) it’s been treated 4 times with surgery, radiation, and finally chemo. I did expose myself to a considerable amount of EM radiation in my younger years in the form of excessive television, and video games. Could this have caused my cancer?
not a doctor, but TV and the like don't produce ionizing radiation which is the energy types of EM radiation that actually cause genetic damage. Otherwise, any heat or any light could be considered a danger.
Sometimes you just get unlucky. I'm 38 and have stage 4 cancer of something I shouldn't have to screen for another 12 years, I have no high-risk behaviors, no family history or genetic defects, when talking with a genetic consultant about my behaviors and the results of genetic testing I'm literally less than one in a million case of bad luck, sometimes bad stuff just happens.
I feel your pain Garith. Cancer’s no fun, and the stroke of bad luck seems to brush over us more than others. Just lucky that way, I guess 😜 I wish you the best of luck with your diagnosis, and am here, if you want to send a message, or anything like that.
@@kevinmoore2501 Well, things could be worse, my first opinion was that I'd be dead a month ago max without treatment and gave me 2-3 years max with it, chemo only with no further plans. Dude even sent in a chaplain and hospice care to talk with me.
I, of course, got a second opinion and am currently at a place that focuses on cancer and they seem more optimistic especially given my age. Currently on round 14 of chemo treatments with plans to evolve around how the treatments progress as I've already had my chemo treatments changed as new data came in.
I think I'm in about the best place I could be given the initial bad luck so I feel pretty fortunate. The offer goes to you as well if you'd like someone to talk with, though you sound like you're well versed in this rodeo already.
I would tend to agree, Garith. This is my 4th recurrence of cancer. The first two times, I had surgery, which permanently handicapped me. Because of the location of my cancer (tumor), however, the only real handicap, which I’m working to overcome is my loss of balance, due to my cerebellum being removed to allow more buildup, and drainage of chronic hydrocephalus which I have now. My team, god bless them, have done so much for me from surgery to radiation, months of therapy, etc. They really rebuilt me, and I’m forever appreciative, and indebted to all of them for that.
I love that he made a video about this because cancer is definitely a rising problem in America today. It is a very scary topic because a lot of the times cancer is uncontrollable and can effect any one at any time. Obviously if you excessively smoke or drink then you are giving yourself a higher risk of developing cancer in your lungs or liver. Yes, there are many cases where people that have never smoked or drank in their life will develop cancer in those areas and it is uncontrollable. However if you do participate in those activities then the consumer should understand that they are at a much higher risk and a very likely to get it compared to others. I knew that being healthy and taking precautions can help avoid getting most diseases but I was not completely aware that being healthy can even prevent some cancers. This does make me feel a little more at ease knowing that I do have some control over this disease because most of the cancers do happen spontaneously and without any reason or any way to prevent it from that person. Cancer has effected me in many ways in my life and it is great to see that I can control it to an extent and that I can have some say in this disease prevention.
Great video. Good job man
you didn't even mention meat or dairy
Not smoking is never having smoking or having quit 5 years ago, but in my case, as a person who has not habit of smoking, but smokes in social situations (about twice a month, or less), and smokes a small amount of cigarettes, am I a smoker or a non-smoker? (Ps.: I'm not a teenager or a college student, who is in process of acquiring the addiction)
You're obviously a smoker.
By definition you're a "moderate smoker" . I'm not sure if your risks are any higher than someone who lives in a downtown core with lots of car exhaust fumes though. I don't "smoke" but my lungs are probably pretty bad. xD
"social smoking" is how most people start smoking. SO over the next few years you might become a full blown smoker, but your still in the moderate category now.
And what about downwinders

Well, I know that I'm going to blame children for getting cancer.
Be healthy. Eat healthy.
knowing is not enough, If we want a healthy population, we need to have more engaging tactics. a great example was the Y program with prediabetes patients. As per exercise, great ideas are parks with public exercise machines (popular in eg SKorea, some parts of Europe, afaik).. but what else? we need to stop talking AT the people who then just nod nod and leave.
Has he talked about fluoride yet?

I'm not afraid of cancer because I'm not going to get it
Sad thing is many people choose death over a lifestyle change
I think it comes from the mentality that we're all inevitably going to die, so what's the point, you know?

I feel like the more you worry about it the more likely you are to get cancer. I know this isn't true. Maybe it's because I'm still young but I just don't worry about cancer whatsoever.
Smoking what tho?

I do believe that many cancers can be preventable. Like skin cancer because you should wear sunscreen when out in the sun, even though I sometimes do not or I wear tanning lotion and not being out in the sun for too long will help with not getting skin cancer. Lung cancer can be preventable if you do not smoke or if you do then should quit smoking to help prevent it. There are some cancers though that cannot be preventable like breast cancer and sometimes cancers that run through your family and have been in your family in the past. I agree with him when he says that cancer is the "silent killer." It really is because many people never know they have cancer until it is too late because some people do not have symptoms for cancer or the cancer does not effect them till it has been in their body for a while.
Being a survivor of hodgkins lymphoma not once but twice, I believe cancer is 100% unbiased. Do people who have never gone out in the sun get skin cancer? Yes. Do those who have never smoked a day in their life get lung cancer? Yes. Of course there are those more susceptible to the "cancer genes" whether that be from heredity or having already had cancer. But whether you try to prevent it or not I think getting cancer is inevitable to those who get it. Some cancers cannot be traced to how those who have it get it. Not hereditary or lifestyle choices its just the luck of the draw. They say mine could have come about from having mononucleosis but I know many if not hundreds that have had mononucleosis and did not get cancer. I under what he is saying, how there are causes of some cancers but those also don't have a strict guideline. Some people smoke there whole lives and never get lick of lung cancer. Then there are those who tan every single day in a tanning bed, tan outside and never get skin cancer or any type of cancer. Cancer is unbiased, it does not matter your age, race, morals, background, family life or lifestyle. If you're "meant to get cancer" you will.
I first want to say that I offer my condolences, as to having been through hodgkins lymphoma twice, and wish you good luck in the future. You stated that cancer is 100% unbiased, and I have to respectfully disagree with you. I understand where you are coming from, as that I agree that there are times when people will do everything to put them at higher risks, and still never get cancer throughout their life. But, even though a majority of the time people develop cancer at random and couldn't have prevented it, I wouldn't go as far to say that it is 100% unbiased as that there are often times as well where the patient could have prevented it according to their lifestyle. There is also the hereditary factor, where if a certain cancer is known to have run in the family, the individual can possibly have a better chance of the particular diagnosis, and that is just a fact. Even though each case, and person, and disease is different, there's just often times when the hereditary factor can be reasoning as to diagnosis.

"Close to half of cancer deaths could be have been prevented". And more than half couldn't have been, which is why chance plays an important, seemingly more important, role?

get healthy, go vegan.
Don't eat fast food processed food - stay with natural food and gym ur body will be good
There are studies that show that veganism has a strong cancer prevention effect across the board, with many different types of cancer.

Obesity is not a behaviour
He probably means overeating or eating an unhealthy diet.
