Dave Coulier, the well-known star of the television series *Full House*, has announced that he is currently undergoing treatment for tongue cancer, just one year after successfully battling non-Hodgkin lymphoma. In an interview with the TODAY Show on December 2, 2025, Coulier shared the details of his new diagnosis and provided an update on his health journey.
Reflecting on the past year, Coulier described his experience with chemotherapy following his lymphoma diagnosis as a “roller coaster.” In April 2025, he celebrated the news that his treatment had been successful and that he was cancer-free. However, during a recent follow-up scan, doctors discovered a new, unrelated cancer at the base of his tongue.
Coulier recounted the shocking moment he learned about his diagnosis. “To go through chemotherapy and feel that relief of whoa, it’s gone, and then to get a test that says, well, now you’ve got another kind of cancer … it is a shock to the system,” he said. After a PET scan revealed concerning results, the actor was informed, “We don’t know what it is, but there’s something at the base of your tongue.”
Describing his symptoms, Coulier explained, “It was very painful. It’s like if you bit your tongue, but the pain just lasted every single day.” Initially, a biopsy did not indicate any signs of cancer, but a subsequent PET scan showed that the growth on his tongue had increased significantly. This led to a follow-up biopsy that confirmed his diagnosis of early-stage, P16-positive oropharyngeal squamous cell carcinoma.
Coulier reflected on the moment he learned about the new cancer, saying, “They said it’s totally unrelated to my non-Hodgkin lymphoma. This is a new cancer. … I said, ‘Are you kidding me?’” Despite the distressing news, the comedian expressed optimism about his prognosis. “We found it early enough where it’s very treatable. … It’s got a 90% curability rate,” he stated.
In light of his diagnosis, Coulier’s medical team has recommended an aggressive treatment plan. He is set to undergo a total of 35 radiation treatments, scheduled from Monday to Friday for the remainder of the year. With a positive outlook, Coulier remains hopeful about his recovery as he embarks on this new chapter of his health journey.
His experience serves as a reminder of the importance of regular medical check-ups and the need for vigilance in monitoring health, particularly following a cancer diagnosis. Coulier’s journey continues to inspire many, as he navigates these challenges with resilience and determination.
