WASHINGTON — Senator John McCain, the 2008 Republican presidential nominee known for his independent streak over more than three decades representing Arizona in the Senate, has brain cancer, his office disclosed Wednesday night in a statement from the Mayo Clinic.
“Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot,” the statement said. “Treatment options may include a combination of chemotherapy and radiation.”
Medical experts said his condition was extremely serious. Eugene S. Flamm, chairman of neurosurgery at Montefiore Hospital in the Bronx, said that “a glioblastoma is the most common and most malignant of brain tumors.”
The median survival is about 16 months, he said. Senator Edward M. Kennedy, Democrat of Massachusetts, died in 2009 from this kind of aggressive brain tumor, which almost always grows back even after chemotherapy and radiation.
Former President Obama and President Trump tweeted the following:
John McCain is an American hero & one of the bravest fighters I've ever known. Cancer doesn't know what it's up against. Give it hell, John.
