The name of the tumor is Astrocytoma (also known as Glioblastoma).
Astrocytomas are tumors that arise from astrocytes—star-shaped cells that make up the “glue-like” or supportive tissue of the brain.
These tumors are “graded” on a scale from I to IV based on how normal or abnormal the cells look. There are low-grade astrocytomas and high-grade astrocytomas. Low-grade astrocytomas are usually localized and grow slowly. High-grade astrocytomas grow at a rapid pace and require a different course of treatment. Most astrocytoma tumors in children are low grade. In adults, the majority are high grade.
Location
Astrocytomas can appear in various parts of the brain and nervous system, including the cerebellum, the cerebrum, the central areas of the brain, the brainstem, and the spinal cord.
Symptoms
Headaches, seizures, memory loss, and changes in behavior are the most common early symptoms of astrocytoma. Other symptoms may occur depending on the size and location of the tumor.
Cause
Like many tumor types, the exact cause of astrocytoma is not known.
Treatment
The first treatment step is surgery to remove as much tumor as possible. Surgery is almost always followed by radiation. Chemotherapy is often given at the same time as radiation and may be used to delay radiation in young children.
Re-Growth
Tumor re-growth can be treated with additional surgery, another form of radiation, a different chemotherapy drug (or combination of drugs), or any number of new approaches to treatment currently in development. These new therapies are offered in organized research studies called clinical trials.
