BRAVE Alex Trebek confesses he’s losing his war with killer pancreatic cancer — and is set to quit his super-hit game show, Jeopardy!

“Alex is done,” says a source close to the show. “He’s quitting in a matter of weeks!

“He doesn’t want any sympathy. He doesn’t want anyone watching the show to say ‘poor Alex’ as he struggles along. He wants to go out with his head held high.”

This has become the latest and saddest development in the game show host's career as his career continues to wind down due to his cancer.
