Alex Trebek has been the host of the TV show Jeopardy! for the past 35 years but this could be his last.

Trebek is battling Stage-4 Pancreatic Cancer and has been forced to resume Chemo treatments to fight the cancer.

Trebek told CTV that he has started to develop sores inside of his mouth and it makes it difficult to enunciate.

He said during the interview that he will continue to host the show as long as his skills don't diminish.
