Who is more likely to get acute lymphoblastic leukaemia

Acute lymphoblastic leukaemia (ALL) is rare, but anyone can get it.

It's not always clear what causes it.

You might be more likely to get it if:

you're a child or young adult - it's most common in children aged 4 and under
you have a genetic condition such as Down's syndrome
you've had certain types of chemotherapy treatment in the past
you were exposed to a lot of radiation or had radiotherapy treatment in the past, especially when you were a child
you are exposed to high levels of a chemical called benzene
you have a weakened immune system, for example you have HIV

It's important to get any symptoms of acute lymphoblastic leukaemia checked by a GP.
