Brain cancer is a very serious cancer diagnosis that no one wants to hear. While there are hundreds of brain and spinal cord tumors, some occur more frequently than others.
According to the
1. Low Grade Astrocytoma
Low grade astrocytoma is a type of glioma; gliomas are the most common types of primary brain cancer—45 percent of all primary brain cancers. The low grade astrocytomas are 54 percent of gliomas, and are not as aggressive as other forms of brain cancers. Many patients survive ten years or more after diagnosis, though the average survival rate is five to six years.
2. High Grade Astrocytoma
High grade astrocytomas are the most malignant form of astrocytoma. 50 percent of high grade astrocytoma patients survive 12 months after surgery. Out of all gliomas, high grade astrocytomas account for more than 25 percent.
Astrocytomas in between low grade and high grade account for ten percent of gliomas. Astrocytoma gets its name from the cells it forms on—astrocytes, a type of glial cell.
Ependymoma accounts for six percent of gliomas and 60 percent of spinal cord tumors. Ependymoma forms along the lining of the ventricles in the brain, though it occurs most often in the fourth ventricle. The BC Cancer Agency points out that patients with ependymoma survive for a while after diagnosis.
Another type of glioma, oligodendrocytomas have a five percent prevalence. Oligodendrocytomas form on the white matter of the cerebral hemisphere of the brain, and symptoms are similar to low grade astrocytoma's symptoms.
