Dave Coulier Shares Honest Health Update Amid Cancer Battle After Fans Express Concern
Full House star Dave Coulier just shared an honest health update amid his cancer battle after fans expressed concern.
On Thursday, May 7, the actor, 66, took to Instagram with a direct response to fans after many pointed out his changed appearance.
In October 2024, Coulier was diagnosed with Stage 3 non-Hodgkin lymphoma. He found out he had a second type of cancer, carcinoma, in his throat in October 2025.
"Hey, everyone, it's Dave," he began the clip. "I haven't posted in quite a while, and the last time I did, some of you, you know, said that I looked differently and I sound differently. And I do. And what you're seeing is the side effects of extensive radiation that I went through for carcinoma in my throat."
Additionally, the actor who played Joey Gladstone in Full House noted that he hasn't been able to eat solid food in months, losing 45 pounds as a result.
"It's affected my ability to speak," he acknowledged. "Some of you said that I sound differently. So yeah, you're right on with what you're seeing and what you're hearing."
To conclude his unexpected health update, Coulier noted that he has kept busy with artwork and creative writing offline.
