Cologuard vs FIT for Colorectal Cancer Screening
HTML-код
- Опубликовано: 8 июл 2024
- In this episode we talk about two important non-invasive screening tests for colorectal cancer called Cologuard and Fecal immunochemical Test (FIT). Both these coloroectal cancer screening tests have their pros and cons. Understanding the sensitivity and specificity of these tests is important in understanding which test is best at detecting colorectal cancer. Remember colonoscopy remains the best screening test for colorectal cancer as it is not only the best at detection but can reduce the risk of colorectal cancer by identifying and removing polyps or precancerous lesions.

My mom just got her Cologuard back and her results show she is positive. :( we are scheduled for a consultation for a colonoscopy next. I’m praying she doesn’t have cancer. I’m afraid of losing her. I don’t know what I would do without her. :(
Is your mom ok?
Nice job and thanks for an accurate comparison. To survive colon cancer you need to detect it early. Clearly, Cologuard does this much better than FIT. I'm guessing there are no late stage cancer victims out there that FIT missed in it's early stage (or even precancer stage) bragging about the money they saved. Cologuard is done once every 3 years and cost's medicare just over $500 0r $166 per year. Even at list price of $649 which nearly nobody pays, Cologuard costs $216 per year. Sounds like a bargain to up your chances of catching treatable cancer significantly.
Any false positive is better than a false negative, colonoscopy is not perfect either and misses as much as 11% of cancers as well for various reasons. When it misses it's a real problem as you're not due back for 10 years with cancer progressing to late stages.
Appreciate the comment. Just to clarify colonoscopy is highly sensitive and specific for colorectal cancer. Colonoscopy has < 1% miss rate for colorectal cancer. Significantly better than any noninvasive test. We should always choose the best test that fits our situation, but I typically recommend colonoscopy because of all the advantages.
@@iMedSchool I have never read any study that suggests a 1% rate for colonoscopy. If it has an advantage it's the ability to remove what's found at the time of the test. The risks that come with colonoscopy make it difficult for me to understand why we would consider colonoscopy a first choice for routine screening. The worst thing that can happen with cologuard is the patient would get a very thorough colonoscopy. There are many adverse things that can happen to complete a colonoscopy. Complications from a colonoscopy recently took the life of a 50 year old gal from my hometown. One day soon hopefully we'll be able to put invasive screening tests behind us.
This video is incredibly helpful! I am curious why you say colonoscopy prevents colon cancer. Isn’t it a screening tool like Cologuard and FIT? Does “prevention” come because polyps are removed? Polyps can still develop post colonoscopy, no? I will choose one of the non-invasive options. Thanks for the video!
Colonoscopy removes precancerous polyps thus decreasing the risk of colorectal cancer. Non-invasive options are less sensitive and specific for both colorectal cancer, as well as, precancerous lesions, like polyps. You should choose whatever method best fits you and your health.
Colonoscopy removed precancerous polyps. It also detected other medical conditions like colitis, inflammatory bowel disease, and diverticulosis. Cologuard doesn’t. It tests blood in the stool.
I would like to know say I do the Cologuard testing, and it comes back positive, and you have to go in to do a colonoscopy will the Ins. Medicaid pay for that?
A colonoscopy for a positive cologuard is consider a diagnostic test. It will still be covered but there may be some expense as it is no longer a screening test. Checking with your state plan to clarify would be good idea. Great question!
Just get the colonoscopy. If the cologuard gives you a false positive you can be still charged. I would skip cologuard and just take the nasty prep and get it over with.
Thank you for this video. I want to mention, however, that it disappoints me greatly when doctors say that a test is the "only" way to prevent cancer. First off, they don't prevent cancer, they only detect it if it's there. Pre-cancerous polyps can be removed, but that does nothing to stop others from growing. Secondly, there are several ways to prevent colon cancer. Exercise reduces the rate of this cancer by 20%, eating lots of fruits and vegetables, avoiding processed meats, junk food, smoking, and excess alcohol all reduces risk. These need to be said instead of insinuating that getting a test is the only way.
Absolutely agree that research has shown a high vegetable diet and regular cardiovascular exercise decrease the risk of colorectal cancer, as well as, the risk of other cancers. Colonoscopy is the only test that decreases the risk of colorectal cancer in the future. This is important to understand to differentiate colonoscopy from other colon cancer screening tests. I wish more people focused on healthy eating and regular exercise.
@@annbaker2219 Bowel wall thickening on a imaging study, like CT or MRI, can represent a lot of things from benign conditions to worrisome conditions. It is important to get it checked out if an imaging study shows abnormal thickening.
My spouse was a 40-year-old vegan with an active lifestyle, and he died of colon cancer. Vegetables are good for you, exercise is good for you, but don't count on it as a substitute for cancer screening.
@@JM.5387 I never said it was a substitute. I was merely saying there are ways to prevent it. Not saying it will work 100% of the time
It reduces the risk of getting it but you can still get it just like you can still get breast cancer and ovarian cancer. Colonoscopy removes precancerous polyps but nowhere does it say that stops them growing. That is why doctors tell you when you come back. Take it from someone who stage 3 colon cancer if there for me to 100 percent prevent my cancer from returning I will gladly do it. I live in the reality that you can’t prevent things from happening.
