Astrocytomas and Glioblastomas

What is an astrocytoma?

Astrocytomas are glial cell tumors developed from connective tissue cells called astrocytes. They are most often found in the cerebrum (the large, outer part of the brain), but also in the cerebellum (the back of the brain). Almost 50% of primary brain tumors are astrocytomas, the most common type of glioma.

Astrocytomas can develop in people of any age. It is one of the most common brain tumors in adults and children.

High-grade astrocytomas and glioblastoma multiforme:

High-grade astrocytomas, called glioblastoma multiforme, are the most malignant of all brain tumors. Cerebellar astrocytomas are gliomas commonly found in children in the cerebellum. In adults, astrocytomas are more common in the cerebrum.
