Treatment for brain cancer depends on the type, size, location, and grade of the tumor, as well as the patient’s overall health. Common treatment options include surgery, radiation therapy, and chemotherapy. Surgery aims to remove as much of the tumor as possible. Radiation therapy uses high-energy beams to kill cancer cells, while chemotherapy involves the use of drugs to target and destroy cancer cells. Newer treatments, such as targeted therapy and immunotherapy, are also being explored to improve outcomes.
