Most often, brain tumors are gliomas, growths that develop in tissue that surrounds and supports nerve cells. Glioblastoma multiforme is the most common type of glioma. Glioblastoma develops in the cerebral hemisphere (most commonly in the frontal lobe). Characterized by a globular mass or mass lesion, glioblastoma leads to necrosis, fatty degeneration, and hemorrhage. The tumor is usually solid and grows rapidly, increasing pressure in the brain.

Symptoms of glioblastoma include, but may not be limited to, headaches, slowed thinking, and in advanced stages, fatigue, seizures, and coma.

MRI and CT scans are useful in evaluating tumor extension. Surgery is an option for treatment but can lead to partial paralysis, changes in sensation, weakness, and impaired intellect. Most glioblastoma patients undergo intracranial radiation and chemotherapy if surgery proves ineffective.

The survival rate of glioblastoma patients is extremely poor. Mean survival length is eight to ten months after diagnosis and less than 10 percent survive after two years.
