Brain cancer refers to an abnormal growth of cells in the brain which form a tumour. Tumours can start in the brain, or can develop from cancer that has spread from other parts of the body.
Primary brain tumours can either be benign (non-cancerous) or malignant.
- benign: grow slowly and unlikely to spread to other parts of the body
- malignant: cancerous tumour that grows rapidly and may invade other body parts
A brain tumour is usually diagnosed by conducting a number of tests, including a CT scan and an MRI.1
