Brain tumours - A to Z

The brainThis page links to content about brain tumours.

Brain tumours affect around 8,000 people each year in the UK and there are many different types. It is important not to confuse cancers that start in the brain (primary brain tumours) with cancers that spread to the brain from elsewhere in the body.

Brain tumours can develop at any age but are most common in people aged between 50 and 70. Brain and spinal cord tumours can also develop in children. Though rare, they are more likely to affect young children than teenagers and young adults.

We do not know what causes most brain tumours. Ionising radiation and some inherited conditions are the only established causes, but these risk factors do not account for most cases. A weakened immune system can increase the risk of developing a lymphoma in the brain.
