In November 2019, Murphy spoke about his son Ford — who was diagnosed with neuroblastoma in October 2018 — while presenting an award to Dana Walden (who was being honored for her work with the UCLA Jonsson Comprehensive Cancer Center, during Variety's Power of Women event), revealing that his child was "cancer-free" after being diagnosed with "a tumor the size of a tennis ball at 18 months" old three years previous.

"Ford went through a six-hour surgery and years of intense exams, which required hours and hours of anesthesia. I cannot express to you in this room how difficult this was on him, how difficult this was for our family," he said, adding that while he has yet to "emotionally recover" from it all, "Ford has."
Opening up about the life lessons he learned from the difficult experience, Murphy stressed that "this is a disease that touches us all."
"We must help and we must be prepared and we must be proactive," he shared, adding that last year his family made a $10 million donation to the Children's Hospital, where Ford received treatment — thanks to Walden. "There is now a wing dedicated under Ford's name that specializes in helping children without our resources."
