VIDEO: 'Jeopardy!' host Alex Trebek gives moving, faith-filled health update one year after pancreatic cancer diagnosis

Alex Trebek, longtime "Jeopardy!" host, gave a moving video update on his health and his progress in fighting cancer.

Doctors diagnosed Trebek, 79, with stage 4 pancreatic cancer in 2019.

What are the details?

On Wednesday, Trebek released the video lauding faith and determination as his motivators to survive pancreatic cancer.

In a video shared on the long-running TV game show's YouTube channel, Trebek said, "If you've got a minute, I'd like to bring you up to date on my health situation. The one-year survival rate for stage 4 pancreatic cancer patients is 18 percent. I'm very happy to report I have just reached that marker.

"Now," he continued, "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 joke with friends that the cancer won't kill me — the chemo treatments will."

Trebek said that though he sometimes found himself at a loss in battling the disease, he never gave up hope.

"There were moments of great pain, days where certain bodily functions no longer functioned, and sudden massive attacks of great depression ... made me wonder if it really was worth fighting on," he continued.

Trebek said that he brushed those thoughts quickly aside — because he owes a debt to his wife and "soul mate," Jean, who the game show host said has "given all her help to help me survive."

"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," he added. "And it certainly would have been a betrayal of my faith in God and the millions of prayers that have been said on my behalf."

Optimistic about his future?

Trebek pointed out that his oncologist is optimistic about his future as a continued cancer survivor.

"He said, 'Alex, even though the two-year survival rate is only 7 percent' he was certain than one year from now the two of us would be sitting in his office celebrating my second anniversary of survival," he revealed. "And you know something? … If we take it just one day at a time with a positive attitude, anything is possible. I'll keep you posted."
