Children's cancer mortality rates in the UK are highest in the under-fives age group, with around 1 in 3 (34%) of all new cancer deaths occurring in this age group (2021-2023).
Childhood cancer usually has no known cause. For most cancer types incidence increases with age, which largely reflects cell DNA damage accumulating over time. Damage can result from biological processes or from exposure to risk factors.

Children's cancer mortality rates have decreased by a third (33%) in the UK since the early 2000s and rates have decreased by around a seventh (15%) in the last decade (2021-2023).
