“Full House” Star Dave Coulier Shares Shocking New Cancer Diagnosis After Beating Lymphoma
Just months after celebrating remission from a serious blood cancer, beloved actor and comedian Dave Coulier revealed a startling new health challenge. The former “Full House” star has been diagnosed with a different form of cancer — one that he says came as a complete shock.
From Lymphoma Victory to a New Diagnosis
In October 2024, Dave Coulier disclosed he had been diagnosed with stage 3 Non‑Hodgkin lymphoma after swelling in his groin turned out to be a rapidly growing B‑cell tumor. In an article with ABC7 News, “Coulier shared the news Wednesday during an interview on ‘Today.’…Coulier said he has ‘B cell lymphoma,’ which he described as ‘aggressive.'”
He underwent a rigorous course of chemotherapy, during which he shaved his head and described the experience as “a rollercoaster ride” of surgeries, treatments, and emotional highs and lows. By late March 2025, the good news arrived: Coulier’s representatives confirmed he was officially cancer‑free. “One of the few times in my life when ‘zero’ has been a great number to hear,” he told People magazine.
A “Shock to the System” — Tongue Cancer Diagnosed
However, the relief was short‑lived. During a routine follow-up PET scan this fall, doctors noticed a suspicious spot at the base of his tongue. After further testing, the 66-year-old learned in October 2025 that he has a form of head and neck cancer —p16‑positive squamous cell carcinoma, also described as HPV‑related oropharyngeal tongue cancer.
“It is a shock to the system,” Coulier admitted in a recent phone interview. “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.” He emphasized that this new diagnosis is totally unrelated to his previous lymphoma.
Treatment, Prognosis, and a Message of Hope
Thankfully, Dave Coulier’s doctors told him that the new cancer, thanks to early detection, is “very treatable.” He has begun a course of 35 radiation treatments, expected to run through the end of 2025. Coulier expressed cautious optimism: “It has a 90-plus percent curability rate,” he said. He urged people to keep up with regular health checkups, screening tests, and not to ignore odd symptoms — because, as he put it, early detection saved his life twice.
Despite the emotional toll on him and his wife, Coulier remains determined. “I’m going to get to the other side of this,” he vowed.
Dave Coulier: Why His Story Matters
Dave Coulier’s journey — from one cancer battle to another — underscores a critical truth about health: beating one disease doesn’t erase the risk of another. For many, hearing about two separate diagnoses in such quick succession might prompt fear. But his openness also serves as a rallying cry for vigilance, screenings, and self‑advocacy.
His story becomes especially powerful given his platform and recognition from a generation that grew up watching him. By sharing not only his triumphs but his setbacks, Coulier is reminding people that sometimes survival isn’t a one‑and‑done deal — but with hope, treatment, and early detection, it can be a second chance.
