Understanding cancer
Types of cancer
Childhood cancer includes various diseases caused by uncontrolled cell growth. This page covers common types, symptoms, and treatments.

4,200 children and young adults are diagnosed with cancer in the UK each year. There are around 1,900 new cases of childhood cancer in the UK every year, spread across 76 types of children’s cancer that can be put in 12 main groups. The most common are: leukaemia (30%), brain, CNS and intracranial tumours (20%) and lymphomas (11%). There are around 2,600 new cancer cases in young people in the UK every year, that’s around 7 every day.
The types of cancer affecting children are quite different from the cancers that affect teenagers and young adults (TYA); TYA cancers are different again from the types of cancer that typically affect adults aged 25+.
Thanks to investment in research and treatment, survival has increased dramatically over the past 50 years and four out of five young cancer patients can be successfully treated.
Below you will find information about the different types of cancer which can affect children, teenagers and young adults.
