Brain tumour. Coloured 3-D computed tomography (CT) scan showing the location of a tumour (green) within a patient's brain. A brain tumour is an abnormal growth in or on the brain which is not always cancerous (malignant). Primary tumours develop directly from tissues inside the skull,of which about 60% are gliomas within the brain; most other primary tumours arise from membranes which cover the brain. Secondary tumours are always malignant and spread via the blood from tumours elsewhere in the body,typically from the lung or breast. Brain tumours produce compression and may seriously damage mental functioning. When possible tumours are removed surgically | |
