Alex Trebek Says Chemo Treatments Are Leaving Him in Tears

The "Jeopardy!" host is battling stage 4 pancreatic cancer.

Cancer is taking a toll on Alex Trebek, who admitted to suffering “deep sadness” during an interview with “Good Morning America.” 

“I have a good day and then the next day it turns south on me for no reason that I can fathom,” he told co-anchor Robin Roberts. 

The beloved “Jeopardy!” host is battling stage 4 pancreatic cancer and is undergoing aggressive chemotherapy. He said that the treatments have left him weak and depressed.

“Surges that come on suddenly of deep, deep sadness and it brings tears to my eye. I've discovered in this whole episode, ladies and gentlemen, that I’m a bit of a wuss,” he said.

“Chemo affects people in different ways and people have to understand that, and that there's nothing wrong with saying, 'Hey, I’m really depressed today and I have no idea why.'”

Despite the grueling chemo regimen, Trebek has not lost any hair.

Dr. Allyson Ocean, an oncologist with Weill Cornell Medicine, explained to Inside Edition why Trebek looks as well as he does. 

"Just because someone looks good with pancreatic cancer doesn’t mean they are not experiencing side effects. It is a positive sign though that he does look well and has maintained his weight," she said. 

“Jeopardy!” has finished filming for the season and the host said he plans to spend the summer hiatus resting and recovering. 

“I just have to get strong, as you know, the chemo takes it out of you,” he said. “I feel so weak all the time. That’s not a good place to be. Hopefully everything is going to turn out well and I’ll be back on the air with original programming come this September.”
