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, their behaviour under the microscope (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.

The following is not an exhaustive list of brain tumour types. Information on other brain tumours that occur less frequently in adults, and/or more frequently in children, are listed on the child brain tumour types page.
