McCain receiving treatment for side effects of cancer therapy, 'looking forward to returning to work'

McCain's Senate colleagues are hopeful he will be back at work next week.

McCain, 81, who was diagnosed with glioblastoma multiforme over the summer, "looks forward to returning to work as soon as possible,” his office added.

“He’s receiving treatment for the side effects of the therapy. I feel pretty good about the way the treatment is affecting his underlying cancer. But the treatment has a downside. So he’s tryin’ to get rested up,” Graham said. “I’m very confident he’ll come back and continue to participate for a long time to come.”

“He’s had a heck of a Senate schedule, and I hope he’ll take some time to regroup, do a little rehabilitation on his leg and come back,” Graham said.
