Detailed explanation-1: -Glioblastoma is the most common type of primary brain tumor in adults and is nearly universally fatal despite advances in therapy. However, cause of death from glioblastoma and other high-grade gliomas depends on many factors, 3 including comorbid conditions, and clinical events surrounding death are frequently complex.

Detailed explanation-2: -Researchers know brain tumors develop when certain genes on the chromosomes of a cell are damaged and no longer function properly, but they aren’t sure why this happens. Your DNA in your chromosomes tells cells throughout your body what to do-it tells them when to grow, when to divide or multiply and/or when to die.

Detailed explanation-3: -Early diagnosis can be an important factor in the outcome of tumors in the brain. Brain tumors are the second leading cause of cancer death in children under age 15 and the second fastest growing cause of cancer death among those over age 65.
