Sen. John McCain has decided to discontinue medical treatment, his family said.The senator was diagnosed with aggressive glioblastoma, a form of brain cancer, last year.The family released the following statement about his health on Friday:McCain, 81, has been representing Arizona for six terms. Since December he has been away from the Capitol.Last summer, McCain flew to Washington to cast a pivotal vote against the Republicans' plan to repeal the Affordable Care Act. The vote, along with McCain's impassioned speech on the Senate floor, came just days after he had surgery.His daughter, Meghan McCain, spoke in May about that decision to travel on, on which she is a co-host. She said that doctors advised against the flight because "basically your brain could explode if you get on a plane this soon after brain surgery."Following Friday's announcement, McCain's family tweeted their thanks for all the support.His wife, Cindy, said, "God bless everyone who has cared for my husband along this journey."Meghan said of the family's supporters, "We could not have made it this far without you."
