Dave Coulier has been diagnosed with tongue cancer, just seven months after overcoming Stage 3 non-Hodgkin lymphoma.
The former star of Full House revealed his latest cancer battle during an appearance on TODAY on Tuesday morning. “In October of this year, I went in for a PET scan, just a routine check-up and something flared on the PET scan,” he explained. “It turned out that I have P16 squamous carcinoma at the base of my tongue. I said to the doctors, ‘Well, did this happen because of the lymphoma?’ And they said, ‘Totally unrelated.’”
Coulier is scheduled to undergo 35 rounds of radiation and is positive about his prognosis, noting there’s a “90% curability rate.”
“The thing that has really saved my life,” Coulier added, “is that early detection saved my life, not just the first time but the second time as well. So I hope you’re getting your check-ups. I hope you get your colonoscopies and breast exams and prostate exams, they will save your life.”
Coulier, 66, was diagnosed with Stage 3 non-Hodgkin lymphoma, a form of blood cancer, in 2024. He announced in March 2025 that he had been given the all-clear.
