Brain Tumors, Pituitary Tumors, and Arachnoid Cysts
Doctors diagnose brain tumors — a growth of abnormal cells in the tissues of the brain — by doing a neurologic exam and tests like an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. Many people get a combination of treatments.
