What is a glioma?
A person with a glioma has abnormal cells in or around the brain that multiply out of control. Over time, these cells can form tumors and spread to other parts of the brain or spinal cord. Gliomas are the most common form of brain cancer. Astrocytomas are the most common type of glioma. The cause of glioma is unknown, but genetics may play a role in determining risk.

What are the symptoms of a glioma?
Symptoms of a glioma vary with the position of the tumor in the brain. Common symptoms include chronic headaches, nausea, changes in mood, problems with speech, difficulty walking, and confusion.

How does the doctor treat a glioma?
Treatment of a glioma varies with tumor size and position in the brain. Treatment measures usually include surgery, corticosteroid medications, anticonvulsants, chemotherapy, and radiation therapy.
