Overview
- Astrocytoma is a primary intracranial tumor. They may arise in the cerebral hemispheres, in the posterior fossa, in the optic nerve, and rarely, the spinal cord. It originates in a particular kind of glial-cells, star-shaped brain cells in the cerebrum called astrocytes. This type of tumor does not usually spread outside the brain and spinal cord and it does not usually affect other organs. Astrocytoma is the most common glioma and can occur in most parts of the brain and occasionally in the spinal cord. To know more about astrocytoma, click here.
