There several types of gliomas. Their names refer to the kind of cells in which they begin:
- Astrocytoma affects the glial cells called astrocytes. The most aggressive astrocytoma is a glioblastoma, which is also called a glioblastoma multiforme.
- Oligodendroglioma affects the glial cells called oligodendrocytes.
- Mixed glioma involves both astrocytes and oligodendrocytes.
- Ependymoma affects cells lining the hollow cavities (ventricles) in the brain and the central canal of the spinal cord.
Each of these types can be further categorized into grades according to how slowly or quickly they grow. A glioblastoma multiforme is a grade IV astrocytoma.
The type and grade of glioma you have will determine your treatment options. Early diagnosis and treatment are important in helping you manage this type of tumor.
