Alex Trebek offers a brutally honest and uplifting update on his pancreatic cancer diagnosis

Friday will mark the the one-year anniversary of the Jeopardy! host announcing his Stage 4 pancreatic diagnosis. This morning, Trebek shared an emotional update to mark the anniversary. "The one-year survival rate for stage 4 pancreatic cancer is 18%," Trebek says in the video posted across Jeopardy!'s social media accounts. "I'm very happy to report I have just reached that marker." Trebek added: "Now I'd be lying if I said the journey had been an easy one. There were some good days but a lot of not-so-good days. I joked with friends that the cancer won't kill me; the chemo treatments will...There were moments of great pain, days when certain bodily functions no longer functioned, and sudden, massive attacks of great depression that made me wonder if it really was worth fighting on." But Trebek said he "brushed that aside quickly" because he didn't want to betray his wife, "who has given her all to help me survive," and the cancer patients who had followed him in his cancer battle. "It would have been a betrayal of other cancer patients who have looked to me as an inspiration and a cheerleader of sorts of the value of living and hope," Trebek added. "And it would certainly have been a betrayal of my faith in God and the millions of prayers that have been said on my behalf."
