Revise: CancerA benign tumour is a growth of abnormal cells that remains contained in one area, usually within a membrane. Its cells do not invade neighbouring tissues or spread to other parts of the body. It is not cancerous.
When comparing tumours, focus on invasion and spread, not simply their size: benign tumours remain localised; malignant tumours invade and can spread.
