Cerebral tumour (Brain tumour)


An abnormal multiplication of brain cells.  This forms a swelling that compresses or destroys the healthy brain cells and – because of the rigid nature of the skull – increases the pressure on the brain tissue.  Malignant tumours grow rapidly, spreading through the otherwise normal brain tissue and causing progressive neurological disability.  Benign tumours grow slowly and compress the brain tissue.  Both benign and malignant tumours commonly cause fits.
