Acute lymphoblastic leukaemia (ALL) is the most common type of childhood cancer. Around 400 children under 14 years old are diagnosed every year. It’s one of the most treatable cancers in children.

The information in this section is aimed at adults caring for a child or young person with blood cancer. Teenage Cancer Trust has information designed specifically for young people.

Adults also get ALL but this is treated differently to childhood ALL.
