Brain tumours may be malignant or benign. The symptoms caused by a brain tumour depend on the size, location and speed of growth of the brain tumour. The typical heralding symptom is an epileptic seizure. Other symptoms may be impaired conscience, headache, nausea and vomiting.
Brain tumours are diagnosed by imaging. At operation, a sample (biopsy) of the tumour is taken. The sample is examined by a pathologist. Assessment of the type of tumour is very important with regard to subsequent treatment decisions.
Malignant brain tumours are treated by surgery, radiation treatment and chemotherapy. The treatment plan is always individualized for each patient.
