Arizona Sen. John McCain, the 2008 Republican presidential nominee with a well-known maverick streak that often vexes his GOP colleagues, has been diagnosed with a brain tumor, his office said in a statement Wednesday.
The 80-year-old lawmaker has glioblastoma, an aggressive cancer, according to doctors at the Mayo Clinic in Phoenix, where McCain had a blood clot removed from above his left eye last Friday.
"Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot," his office said in a statement.
According to the American Brain Tumor Association, more than 12,000 people a year are diagnosed with glioblastoma, a particularly aggressive type of tumor. The American Cancer Society puts the five-year survival rate for patients over 55 at about 4 percent.
It's the same type of tumor that struck McCain's close Democratic colleague in legislative battles, the late Ted Kennedy of Massachusetts.
The tumor digs tentacle-like roots into normal brain tissue. Patients fare best when surgeons can cut out all the visible tumor, which happened with McCain's tumor, according to his office. That isn't a cure; cancerous cells that aren't visible still tend to lurk, the reason McCain's doctors are considering further treatment, including chemotherapy and radiation.
In a statement on Twitter, his daughter, Meghan McCain, spoke of the shock of the news and the anxiety over what happens next. "My love for my father is boundless and like any daughter I cannot and do not wish to be in a world without him. I have faith that those days remain far away," she said.
