"[Deadpool] is a character who has cancer and suddenly all of these kids were reaching out
to me who had cancer, who looked up to this character who sort of, for lack of a more elegant way to describe it, flipped cancer the bird," he told ET Canada
"And I suddenly started meeting kids from all over the place and we were hosting them on set
and you start to see these guys and you think about how lucky and how privileged we are," he added. "Not only to be in the position we are, which we can have a pretty loud megaphone to raise awareness for this, but also that I am one of the lucky people that my kids are healthy and well, and I can't help but project that onto my own life. I want to do everything I can to help people who are going through this and make sure we eradicate this as much as possible."
