Scotland Tonight special report: Ava's Story

Every year in the UK, around 100 children under the age of 14 are diagnosed with neuroblastoma, an aggressive type of cancer.
One of those kids is Ava Bolton from Mauchline in Ayrshire - and now her parents are in a race against the clock to give her the best chance of beating it.
Selena Jackson has been spending time with the family, getting an insight into the devastating impact of childhood cancer.
