| ==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 [[astrocyte]]s. 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 [[Astrocytoma|'''here''']].
| |
| *Astrocytoma is classified broadly into low-grade and high-grade astrocytoma. To know more about high-grade astrocytoma, click [[high grade astrocytoma|'''here''']].
| |
| *Low-grade astrocytoma is classified into four subtypes, and they are as follows:<ref name=lowgradeinfiltrativeastrocytoma1>Low grade infiltrative astrocytoma.
