Most common childhood cancers

Things that cause adult cancer such as smoking and chemicals aren’t obvious causes of cancer in children. Children’s cancers effect in different parts of the body to adult cancers and occur much less often.

The most common types of cancer in adults are skin, breast, prostate, lung and bowel. In children, cancers of the blood and bone marrow, lymph tissue, brain, nervous system, muscles, kidneys, and bone are most common.

Cancer in children tends to respond better to treatment than cancer in adults and overall, cure rates in children are much higher than in adults.

For more information, see the Paediatric Integrated Cancer Service digital resources. See below for an overview of some of the most common cancers affecting children.

Brain & Central Nervous (CNS) System Tumours

What is it?

A brain or spinal cord tumour starts when abnormal cells grow and form a mass or lump. The tumour may be benign or malignant, but both types can be serious and may need urgent treatment. 

What types are there?

There are two main types of childhood brain and central nervous system tumours:

  • Gliomas (Astrocytomas and ependymomas)
  • Medulloblastoma

Brain tumours can be either primary (the tumour starts to grow in the brain) or secondary (more commonly called brain or cerebral metastases), which happen when cancer cells from other parts of the body spread to the brain.

Bone cancers (including Osteosarcoma and Ewing’s sarcoma)

What is it?

Primary bone cancer is cancer that starts on the surface, in the outer layer or from the centre of the bone. As the tumour grows, cancer cells multiply and destroy the bone. If left untreated, it can spread to other parts of the body.

What types are there?

The two most common types of bone cancer seen in children are:

  • Osteosarcoma
  • Ewing sarcoma
