The 66-year-old actor and comedian shared an Instagram update on May 7 about the toll recent cancer treatments have taken on his body. Coulier, a two-time cancer survivor, reminded fans that he was diagnosed with stage 3 non-Hodgkin lymphoma in November 2024 and later with p16 squamous carcinoma at the base of his tongue in December 2025. He said recent PET scans brought good news and the prognosis looks positive for both illnesses.
Coulier said extensive radiation affected his voice and appearance. He revealed he hasn’t been able to eat solid food for months and has lost 45 pounds. He also noted his hair is “kind of growing back” about 18 months after the lymphoma.
