Primary brain tumors are named according to the type of cells or the part of the brain in which they begin. For example, most primary brain tumors begin in glial cells. This type of tumor is called a glioma. Grades of Brain Tumors Grade 1. The cells look nearly normal and grow slowly. Long-term survival is likely. Grade 2. The cells look slightly abnormal and grow slowly. Grade 3. The cells look abnormal and are actively growing into nearby brain tissue. Grade 4. The cells look most abnormal and grow Author: Camille Peri.
Glioblastoma multiforme (GBM) is the most common and deadliest of malignant primary brain tumors in adults and is one of a group of tumors referred to as gliomas.
