Glioblastoma brain cancer is actually the most common type of malignant brain tumor in adults, and the prognosis is grim.

“He’s finished,” one might think upon learning that someone has this very high grade cancer.

This type of brain tumor is also commonly known as glioblastoma multiforme. It’s aggressive and merciless.
