"You've given us strength to carry on," writes Meghan McCain.
John McCain has announced he's decided to discontinue treatment for brain cancer.
The Arizona senator's family released a statement confirming the news on Friday, a year after he was first diagnosed. Following the press release from the family, McCain's wife Cindy and daughter Meghan each shared additional messages to their social media pages, thanking everyone for their support through his battle.
"Last summer, Senator John McCain shared with Americans the news our family already knew: he had been diagnosed with an aggressive glioblastoma, and the prognosis was serious," reads the statement. "In the year since, John has surpassed expectations for his survival. But the progress of disease and the inexorable advance of age render their verdict. With his usual strength of will, he has now chosen to discontinue medical treatment."
"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. God bless and thank you all," the family added.
On Twitter, "The View" co-host Meghan McCain shared the statement, along with her own personal touch.
"My family is deeply appreciative of all the love and generosity you have shown us during this past year," she added. "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."
"I love my husband with all of my heart," wrote Cindy on her own page. "God bless everyone who has cared for my husband along this journey."
