The treatment for angiocentric glioma depends on the size and location of the tumor, as well as the patient's age and overall health. Treatment options may include surgery, radiation therapy, chemotherapy, or a combination of these treatments. Surgery is usually the first line of treatment for angiocentric gliomas, and may involve removing the entire tumor or just a portion of it. Radiation therapy may be used to shrink the tumor or to reduce the risk of recurrence. Chemotherapy may be used to reduce the size of the tumor or to reduce the risk of recurrence.
