The Full House actor said radiation has changed his appearance and voice.
LOS ANGELES — Dave Coulier said recent scans showed good signs after treatment for two cancers, telling fans in a new video that radiation left him unable to eat solid food for months and changed the way he looks and sounds.
The 66-year-old comedian, best known for playing Joey Gladstone on Full House, posted the update after fans asked about changes in his face, weight and voice. Coulier has publicly discussed two separate cancer diagnoses since late 2024: stage 3 non-Hodgkin lymphoma and p16 squamous carcinoma at the base of his tongue. His latest comments offered a plain account of the physical toll of treatment while also pointing to encouraging scan results.
Coulier said in the May 7 video that he had not posted in a while, then addressed the questions directly. He said people had noticed that he looked and sounded different, and he agreed. The changes, he said, came from extensive radiation for carcinoma in his throat. “I haven’t been able to eat solid food in months, so I’ve lost 45 pounds,” Coulier said. He also said the treatment had affected his ability to speak. Coulier smiled while noting that his hair had started to grow back after chemotherapy for lymphoma, a sign that he framed as part of the long recovery from two illnesses in less than two years.
The actor said his PET scans had come back with good news, adding that the outlook appeared positive for both the throat carcinoma and lymphoma. Coulier did not give a date for his next scan or name the medical team overseeing his care. He has previously said the second cancer was separate from his lymphoma and was found during follow-up testing after he had completed treatment for the blood cancer. The second diagnosis, he said in earlier interviews, came as a shock because he had been feeling well before the scan showed something unusual near the base of his tongue.
Coulier first disclosed in 2024 that he had been diagnosed with stage 3 non-Hodgkin lymphoma. He said the illness was found after swelling in his lymph nodes led to tests, and he later underwent chemotherapy. By early 2025, he said doctors had found no sign of that cancer. In December 2025, he publicly revealed a new diagnosis, p16 squamous carcinoma, a head and neck cancer located at the base of his tongue. He said doctors told him the second cancer was not connected to the lymphoma. Treatment for the tongue cancer included radiation, which he has described as a difficult process even as he called the prognosis strong.
In February, Coulier appeared on Good Morning America and said he was in remission from both cancers. “It’s been a roller coaster ride for sure,” he said during that interview. He used the appearance to describe the emotional whiplash of receiving one cancer-free update and then facing a second diagnosis. The new social media video gave a more visible look at the side effects that followed. Coulier said he wanted to explain the weight loss and voice changes rather than let the public guess. His comments came as fans continued to track his recovery through television interviews, social media posts and updates from entertainment outlets.
Support quickly followed from people close to the Full House family. Kelly Rizzo, the widow of Coulier’s late co-star Bob Saget, wrote that Coulier was loved and strong. Actor Scott Weinger, who appeared on Full House, also posted support. Andrea Barber, who played Kimmy Gibbler, praised Coulier with a note that mixed warmth and humor. Coulier’s wife, Melissa Coulier, whom he married in 2014, also responded publicly. The comments reflected the public bond among cast members from the sitcom, which ran for eight seasons and later returned through the Netflix sequel Fuller House.
Coulier said he has stayed busy during recovery with artwork, creative writing and work tied to Awear Market, a wellness-focused brand he has promoted. He did not announce a new acting project in the health update. Instead, the video centered on treatment, recovery and gratitude. His public remarks have also shown how his illness has shifted his role from performer to patient in the public eye. He has said he did not seek that role, but he has continued to speak about the scans and treatments that shaped the past year and a half of his life.
The next public milestone remains unclear. Coulier has not announced a scheduled medical update, a new scan date or another television appearance tied to his recovery. For now, the latest known status is that he has described recent PET results as positive and has said doctors are pleased with his progress. His most recent video left fans with a simple update: the visible changes are real, the treatment has been hard and the scan results are moving in the right direction.
