Alex Trebek has stage 4 pancreatic cancer, but the Jeopardy! host vows to "fight" and "keep working."
He made the announcement in a video message today (Wednesday). In the clip, the 78-year-old said he plans to continue hosting Jeopardy! and jokes that he has to stay alive because he's contractually obligated to do the show for three more years.
Alex has been hosting Jeopardy! since 1984.
