Dave Coulier said Thursday that ongoing cancer treatments have left him unable to eat solid food for months and cost him 45 pounds, a stark update after he said in February that he was in remission from two cancer diagnoses.
“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,” Coulier said in the social media post. “What you're seeing is the side effects of extensive radiation that I went through carcinoma in my throat.” He said the treatment has affected his ability to speak and added, “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.”
The update comes after a difficult two-year stretch for the 66-year-old actor and comedian. Coulier was first diagnosed with stage 3 non-Hodgkin lymphoma in 2024, then was later diagnosed with HPV-related oropharyngeal tongue cancer a year after that. During a six-month checkup and PET scans after his first diagnosis, doctors discovered an enlarged tumor. He underwent 35 rounds of targeted radiation in December, and in February he said he was in remission after battling both cancers. He said Thursday that his prognosis looks good for both the carcinoma in his throat and the lymphoma.
Coulier has also been open about trying to make changes in his day-to-day life after asking why his lymphatic system had “crash[ed].” In April, he appeared on The Kelly Clarkson Show and said he decided to change one thing at a time, starting with his toothpaste. “My toothpaste, my shampoo, the garbage bags, the toilet paper, everything, skin cream, everything,” he said of the products he began reassessing. “I said, 'I need to change this, but how do I do it?' It's a pretty daunting task to change your lifestyle like that,” he said. “So I changed one thing. I replaced my toothpaste.”
The latest post shows the fight is not over, but it also points to the central fact Coulier wanted to leave with viewers: the scans are encouraging, the prognosis is good, and the hard part now is recovery from the treatment itself.
