The most common form of leukemia in children is acute lymphoblastic leukemia or ALL cancer. This cancer of the white blood cells can be very dangerous, as it affects bone marrow and prevents it from producing healthy red blood cells. This puts children at a higher risk for infection. Acute lymphoblastic leukemia symptoms in children include bruising and anaemia. ALL is the only form of leukemia – and one of the few forms of cancer – that is more common in children than in adults.

The brain and the spinal cord make up the central nervous system (CNS). Different types of tumours can start in the CNS. They are named after the type of cell or part of the brain/spinal cord from which they arise. Even though these cancers start in the CNS, they are all different cancers, and need to be treated differently.

This section focuses on brain and CNS tumours that start in the CNS. It doesn’t include information about cancers that spread, or metastasise, to the brain or CNS.
