Gliomas are primary tumors. Gliomas are graded, or divided, into levels based upon their rate of growth and potential for rapid deterioration. The higher the grade, the more aggressive the tumor. Treatments for gliomas depend upon the grade and will typically involve a combination of therapies including surgical removal, chemotherapy and radiation. Astrocytomas, the most common of these tumors, are tumors that sprout from abnormal astrocyte cells, which support neuron function and generation in the brain, among other things. Astrocytomas are graded on a scale of 1 through 4, with 4 the most serious form. Symptoms vary, and may include mental dysfunction, seizures, persistent headaches, vomiting or swelling. The standard treatment is surgery if the tumor is accessible, followed by radiation therapy and chemotherapy. In grades 3 and 4, there is a high probability that the tumor will return, so follow up treatment and diligent follow up is essential.
