Astrocytomas

[Sarah]

Astrocytomas are brain and spinal cord tumors that develop from star-shaped cells (astrocytes) that help nerve cells in the brain (or spinal cord) function. These tumors may be cancerous or not.

The cause of astrocytomas is not known.
Children may have difficulty walking, weakness, vision changes, vomiting, and headaches.
Diagnosis usually involves an imaging test and a biopsy.
Treatment options include surgery, chemotherapy, and radiation therapy.

Astrocytomas are the most common brain tumors in children, accounting for up to 40%. These tumors are usually diagnosed between ages 5 years and 9 years.
