John McCain ends brain cancer treatment effective Friday

McCain chose to decline further treatment for brain cancer, according to a statement by his family

Arizona Senator John McCain's family announced in a statement on Friday that he has chosen to halt treatment for brain cancer. 

"With his usual strength of will, he has now chosen to discontinue medical treatment," McCain's family wrote in the statement.

McCain's diagnosis of glioblastoma, a particularly aggressive form of brain cancer according to Mayo Clinic, came last summer. 

"John has surpassed expectations for his survival,” his family wrote in the statement. “Our family is immensely grateful for the support and kindness of all his caregivers over the last year, and for the continuing outpouring of concern and affection from John’s many friends and associates, and the many thousands of people who are keeping him in their prayers.”

Though McCain has not voted in recent Senate hearings, he has maintained a presence in current politics from his home in Sedona  by expressing his opinions and viewpoints on his Twitter and in official statements.

Since the announcement, McCain’s family has taken to social media to express gratitude for the support McCain has received.

“My family is deeply appreciative of all the love and generosity you have shown us during this past year,” McCain's daughter, Meghan McCain, wrote. “Thank you for all your continued support and prayers. We could not have made it this far without you - you’ve given us strength to carry on.”
