Dave Coulier has shared a health update while addressing online users who have commented on changes to his voice and physical appearance.

The Full House star took to Instagram on Thursday, where he told his followers that “what you’re seeing is the side effects of extensive radiation that I went through for carcinoma in my throat.”

“Hi everyone, it’s me, Dave, and I haven’t posted in quite a while and the last time I did some of you said that I look differently and I sound differently, and I do,” he began. “And what you’re seeing is the side effects of extensive radiation that I went through for carcinoma in my throat.”

Coulier announced he was diagnosed with stage 3 non-Hodgkin lymphoma in Nov. 2024, later revealing in December that he had been diagnosed with p16 squamous carcinoma at the base of his tongue. The second diagnosis arrived a year after he finished treatment for lymphoma.

Coulier continued, “I haven’t been able to eat solid food in months, and so I’ve lost 45 pounds, that’s what you’re seeing. And it’s affected my ability to speak; some of you have said that I sound differently. So you’re right on with what you’re seeing and what you’re hearing.” 

The actor shared a positive health update, explaining he’d recently had PET scans, and that the “prognosis looks good for both the carcinoma in my throat and the lymphoma, so we’re very pleased with all of that.”

Roughly three months ago, Coulier appeared on Good Morning America, where he revealed he was in remission after undergoing surgery for tongue cancer, following additional treatment he received for his stage 3 non-Hodgkin lymphoma.

“It’s been a roller coaster ride for sure,” he said on the television program. “I’m in remission with both cancers. And what a journey this has been.”
