Astrocytoma is a type of cancer that can form in the brain or spinal cord. Astrocytoma begins in cells called astrocytes that support nerve cells.
Astrocytoma signs and symptoms depend on the location of your tumor. Astrocytomas that occur in the brain can cause seizures, headaches and nausea. Astrocytomas that occur in the spinal cord can cause weakness and disability in the area affected by the growing tumor.
Astrocytoma can be a slow-growing tumor, or it can be an aggressive cancer that grows quickly. The aggressiveness (grade) of your astrocytoma determines your prognosis and treatment options.
