The 80-year-old Arizona Republican senator, John McCain has been diagnosed with the brain cancer, as reported by CNN. A Brain Tumor called "glioblastoma" has been removed from his right eye during last Friday surgery at the Mayo Clinic.

Doctor says McCain's recovery is going well

According to the Mayo Clinic's statement, McCain's family is looking for further treatments. These treatments could include radiation and chemotherapy. Doctor says, his "health recovery" is going well and they are confident about his future treatments.

Senator's last week surgery forced him to stay in Arizona, and he missed the votes in the Senate this week.

His surgery delayed the vote on the Senate Republican bill which was scheduled on Monday to replace and repeal the "Obamacare." After the delay, many senators opposed the bill and appealed Mitch McConnel to take a clean action to replace the Affordable Care Act (also known as Obamacare).

"In the aftermath of his diagnosis, further consultations with the Mayo Clinic care team will indicate when he will return to the United States Senate," said by McCain's spokesman.

Support and blessings for his good health by loved ones

It was pointed out by the former US President Brack Obama that McCain is strong enough to put himself out of this fight with life. He is considered as the "national hero" who made more enemies and friends than any other person, and he is the warrior, reported by CNN.

Obama tweeted Today's morning, saying that "John McCain is an American hero & one of the bravest fighters I've ever known."

John McCain's daughter, Megan McCain, paid tribute to her father and released a statement on Twitter.

She said he is the toughest person and no one could break him. " Cancer may afflict him in many ways, but it will not make him surrender. Nothing ever has," she added.

McCain has been elected six times as the Republican Senator and was also the presidential nominee for Republican Party in 2008.

He served more than five years in the prison during the Vietnam war and was tortured. He earned many honors including the Silver and Bronze stars and also decorated with a distinguished flying cross on his retirement as the Captain.

“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,” said by Trump. Lindsay Graham, a senator from South Carolina and McCain's close friend, was emotional about his diagnosis. He said, "God knows how this ends."
