On Wednesday evening, it was revealed that surgeons operating on the senior senator from Arizona had discovered a malignant tumor when they went in to remove a blood clot near his left eye. As Rare previously reported, a statement put out by McCain’s office said that the tumor was a “brain tumor known as a glioblastoma.”

McCain and his family are currently looking at treatment options for the senator, including chemotherapy and radiation.
