Brain tumor Definition: A brain tumor is any mass created by an abnormal and uncontrolled growth of cells either found in the brain (neurons, glial cells, epithelial cells, myelin producing cells, etc.) or spread from elsewhere (metastasis). Brain tumors are usually located in the posterior third of the brain in childhood and in the anterior two-thirds of the brain in adulthood.
