Glioma refers to a type of brain tumor that develops from the glial cells, which are specialized cells that surround and support neurons (nerve cells) in the brain. It is generally classified based on which type of glial cell is involved in the tumor:
- Astocytoma – tumors that develop from star-shaped glial cells called astrocytes
- Ependymomas – tumors that arise from ependymal cells that line the ventricles of the brain and the center of the spinal cord
- Oligodendrogliomas – tumors that affect the oligodendrocytes
Gliomas can affect your brain function and be life-threatening depending on their location and rate of growth. Gliomas are one of the most common types of primary brain tumors.
The type of glioma you have helps determine your treatment and your prognosis. In general, glioma treatment options include surgery, radiation therapy, chemotherapy, targeted therapy.
