Alex Trebek has been diagnosed with stage four pancreatic cancer, he revealed on Wednesday.
The 78-year-old Jeopardy! host announced the sad news on the show's YouTube page.
"Normally the prognosis for this is not very encouraging, but I'm going to fight this, and I'm going to keep working," Trebek says. "And with the love and support from my family and friends, and with the help of your prayers also, I plan to beat the low survival rates statistics for this disease."
"Truth be told I have to, because under the terms of my contract I have to host Jeopardy! for three more years," he jokes. "So, help me, keep the faith, and we'll win. We'll get it done. Thank you."
Trebek has hosted Jeopardy! since 1984, and last October, he renewed his contract to continue hosting the show through 2022.
During his appearance last July on Harvey Levin's show, OBJECTified, he said he could definitely see his life without hosting the beloved game show, and shared that he seriously considered retiring in 2020 before eventually renewing his contract. He even named possible replacements he approves of -- Los Angeles Kings play-by-play announcer Alex Faust and CNN legal analyst Laura Coates.
"If I'm still enjoying it and if I'm not making too many mistakes, then I will continue," Trebek said of his hosting duties. "But there comes a time, of course … [The Price Is Right host] Bob Barker is a perfect example. He was still doing well, but he figured, hey, the time is now. And in life we make a lot of decisions about what we want to do and whether to accept a job, and you should also be able to make an intelligent decision about when it's time to hang things up."
Trebek has dealt with health issues in the past, including suffering mild heart attacks in 2007 and in 2012. Additionally, in 2015 he hosted Jeopardy! seated due to a knee replacement.
"Some of you may have heard that during the holiday break I had a slight medical problem," Trebek said in a video posted by the official Jeopardy! Twitter account. "A subdural hematoma, blood clots on the brain caused by a fall I endured about two months ago."
"Surgery was performed. After two days in the hospital, I came home to start recovery," he continued. "The prognosis is excellent ... And I want to thank all of you for your concern."
