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. Information about other brain tumours that occur less frequently in adults, and/or more frequently in children, can be found on the child brain tumour types page. If you would like information on any other type of brain tumour, please get in touch.
