Arizona Senator John McCain will continue with radiation and chemotherapy treatments for brain cancer, while still working in his office following his MRI on Monday.

The Arizona Republican’s office says he had the MRI at National Institute of Health in Bethesda, Maryland, where he is receiving treatments. 81 Years old senator disclosed his diagnosis in July, Senator returned to senate in August recess and is managing major legislation on the senate floor, the annual defense bill.

"I'm facing a challenge, but I've faced other challenges," McCain said. "And I'm very confident about getting through this one as well."

Earlier in an Interview senator said that he is confident about beating the challenge but also said, “Every life has to end one way or another”.

When asked how he wanted to be remembered, McCain responded: "He served his country, and not always right -- made a lot of mistakes, made a lot of errors -- but served his country, and I hope we could add, honorably."
