Former Full House star Dave Coulier received a new cancer diagnosis just months after defeating Stage 3 non-Hodgkin lymphoma. The 66-year-old actor revealed Tuesday on TODAY that he has P16 squamous carcinoma at the base of his tongue. “In October of this year, I went in for a PET scan, just a routine check-up and something flared on the PET scan,” Coulier 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 will undergo 35 radiation treatments and remains optimistic about his 90% curability rate. “The thing that has really saved my life is that early detection saved my life, not just the first time but the second time as well,” he stated.
