Biden, whose final White House projects included a "Cancer Moonshot" report of recommendations for reimagining how doctors treat the disease, ticked off a number of recent breakthroughs, including injecting viruses into cancer cells (as was done with Beau) and CAR-T cells.
Former Vice President of the United States Joe Biden joined the ABC show "The View" on Dec 13.
Given this history, it's obvious why Meghan ― who joined The View as a co-host in October ― would feel emotional about glioblastoma, and Biden can definitely relate. Biden consoled McCain and said, "There is hope".
The Arizona senator was diagnosed earlier this year with glioblastoma, the brain cancer that killed Biden's son Beau in 2015.
Biden was promoting his new book, "Promise Me, Dad", which is about his son's terminal cancer battle. "This doesn't get easier but you cultivate the tools to work with this and live with this".
Biden moved from his place on the set to sit next to Meghan McCain.
- The View (@TheView) December 13, 2017There are no words I have to convey my enormous gratitude to @JoeBiden and his family - your strength, hope and fortitude are an inspiration to me and so many others daily.
"The thing that I found, and Beau insisted on, and your dad's going to insist on, is you've got to maintain hope". "And if anybody can make it, (it's) your dad". We're like two brothers who were somehow raised by different fathers because of our points of view. I've said it even when your dad got mad at me and said that I should get the hell off the ticket. Come. He'd get on the plane and come. Beau talked about your dad's courage - not about illness, but his courage. "And I would for him".
Though they're on separate sides of the political aisle, Biden has been a longtime friend of McCain's and tweeted a message of support in July after the senator's diagnosis.
"Your strength, hope and fortitude are an inspiration to me and so many others daily", she wrote.
