Adult brain tumour types

There are over 130 types of brain tumour, as classified by the World Health Organisation.

Read more about some of the most common types of adult brain tumours including glioblastoma, astrocytoma and pituitary adenoma.

Brain tumours can differ in terms of the cells they originate from, how quickly they are likely to grow and spread, and the part of the brain they affect. Knowing your tumour's type can therefore help you understand your condition.

As a general rule, brain tumours are named according to the type of cell they start from and/or where in the brain they are located. Information about the most common brain tumour types is below.
