Childhood Cerebral Astrocytoma is a tumor made up of brain cells, and is located in the cerebrum (the main area of the brain). Cerebral astrocytoma is the most common type of cancer in children after leukemia and lymphoma. This type of tumor can be benign (noncancerous), or malignant (cancerous). Symptoms may include: weakness on one side of the body, seizures, morning headaches, nausea, vomiting, tiredness, and changes in personality and behavior. Diagnosis typically includes a CT scan, or an MRI. Treatment may include surgery to remove the tumor, radiation therapy, or chemotherapy. The child’s chance of recovery depends on the size and location of the tumor, as well as his or her age and general health.
