HOW DOES BRAIN TUMOUR OCCUR?
A brain tumour is a group of abnormal cells in the brain. Primary brain tumours start in the brain and can be either benign or malignant. In most parts of the body, a benign tumour is not as serious as a malignant tumour. In the brain, both benign and malignant tumours can be serious and possibly life threatening.
