The hit game show “Jeopardy!” has been a fan favorite amongst television viewers for over 35 years. Decades of airing on television have opened a place in fans’ hearts for the show’s host, Alex Trebek. This made Trebek’s cancer diagnosis a shock for the show’s long-time viewers.

The host broke the devastating news earlier this year. Trebek revealed in March that he had been diagnosed with pancreatic cancer at stage IV. While the TV personality was initially optimistic about treatment, Trebek is now confessing to the news that will worry fans.

The is peeling back layers to reveal his struggles with cancer treatment and its detrimental effects on his hosting skills. In an interview on CTV’s news program, W5, the host admitted that chemotherapy has taken a toll on him. The host even pondered how long before he’ll have to give up the show to a new host.

Trebek says he has aired his concerns to producers of the game show. The host told them, “‘Look, I’m slurring my words. My tongue doesn’t work as much, as well as it used to. The chemo has caused sores inside my mouth. It makes it difficult for me to speak and enunciate properly.’”

According to the host, producers have said they don’t notice the changes. However, Trebek says “I notice those things,” and says that more observant viewers probably do as well. The host then adds, “I’m not as bothered by it because all of the people around me are saying, ‘No, it’s okay.’ But there will come a point where they will no longer be able to say, ‘It’s okay.’”
