Sen. McCain Diagnosed With Brain Tumor After Blood Clot Removed

WASHINGTON (AP/CBS) — Doctors say Arizona Sen. John McCain has a brain tumor associated with a blood clot that was removed last week.

In a statement late Wednesday, doctors reveal that McCain has been diagnosed with glioblastoma, an aggressive cancer. The statement says the 80-year-old senator and his family are reviewing further treatment, including a combination of chemotherapy and radiation.

The senator has been recovering at his Arizona home after doctors at the Mayo Clinic removed a blood clot above his left eye.

The doctors say McCain is recovering from his surgery amazingly well and his underlying health is excellent, according to the statement.

McCain was the GOP's presidential nominee in 2008. A Navy pilot, he was shot down over Vietnam and held as a prisoner for 5 ½ years.

In a statement, President Donald Trump said, "Senator John McCain has always been a fighter. Melania and I send our thoughts and prayers to Senator McCain, Cindy, and their entire family. Get well soon."

Former President Barack Obama said "cancer doesn't know what it is up against."

Massachusetts lawmakers reacted to the announcement on Twitter.

Sen. Ed Markey said "No one is tougher than Senator John McCain. Period."

Rep. Seth Moulton said he was honored to have visited the "Hanoi Hilton" with McCain a few weeks ago.

Sen. Elizabeth Warren, who recently traveled overseas with McCain, says he's "in fighting shape."

Boston Mayor Marty Walsh called McCain an "American hero" and a "true patriot."
