Alex Trebek has suggested in a recent interview that his tenure as "Jeopardy!" host may be nearing an end as he battles pancreatic cancer. The 79-year-old, who has hosted the show for 36 seasons totaling nearly 8,000 episodes, told CTV his skills "have started to diminish."

Trebek revealed earlier this year that he was diagnosed with stage 4 pancreatic cancer. Despite learning he was near remission in May, he needed to go for  another round of chemotherapy in September –– right as the new season of Jeopardy! began. He admitted taping the show is becoming more difficult.

"I will keep doing it as long as my skills do not diminish, and they have started to diminish," he told CTV.

In the interview, Trebek said he's slurring his words and my tongue "doesn't work as well as it used to." Cold sores caused by the chemotherapy, he said, makes it difficult for him to speak and enunciate properly.

"I notice those things and I'm sure there are observant members of the television audience who notice also," he said. "But they're forgiving."
