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