David Livingston/Getty Images Since going public with stage III non-Hodgkin lymphoma in November 2024, Dave Coulier has been candid about his illness, treatment and prognosis before his second diagnosis. Non-Hodgkin lymphoma is a type of cancer that affects the patient's lymphatic system, with "white blood cells called lymphocytes [that] grow abnormally and can form growths (tumors) throughout the body," according to the Mayo Clinic. With his wife Melissa Bring by his side, Coulier has relied on his doctors' "very specific plan for how they were going to treat" the cancer. "That was really a conscious decision of, I'm going to meet this head-on, and I want people to know it's my life," Coulier explained in a November 2024 episode of his "Full House Rewind" podcast after he revealed his diagnosis. "I'm not going to try and hide anything. I would rather talk about it and open the discussion and inspire people." Coulier's treatment is ongoing, with the plan after his diagnosis being for him to complete chemotherapy in February 2025 and be in "total remission." Dave Coulier and Wife Melissa Bring's Relationship Timeline Bring, however, revealed in January 2025 that the treatment is taking its toll on Coulier. "He has some really tough days, and as the chemo has been accumulating it gets a little tougher and more difficult," Bring said during an interview with WXYZ published on Thursday, January 23. She added that on good days, they play a song and have a "dance party with the dogs" to celebrate the positive moments. Keep scrolling for everything Coulier has said about his cancer battle. Coping With His Diagnosis Paul Archuleta/FilmMagic Coulier was first diagnosed in October 2024 after he battled an upper-respiratory infection that resulted in severe swelling of his lymph nodes. When one area swelled to the size of a golf ball, he underwent PET and CT scans and a biopsy, which revealed the cancer. "I went from, 'I got a little bit of a head cold,' to 'I have cancer,' and it was pretty overwhelming," he told People. "This has been a really fast roller coaster ride of a journey."

"Some days are nauseous and dizzy, and then there's other days where the steroids kick in, and I feel like I have a ton of energy," he told People. "I actually skated yesterday with some friends here in Detroit. We just went and skated around and shot pucks, and it was wonderful just to be out there doing something that I love and just trying to stay focused on all the great stuff that I have in my life." Early Detection While Coulier continues his own battle, he's also using his platform to help others understand the importance of early detection. "There's a lot to live for. And if that means talking with your doctors or getting a mammogram or a breast exam or a colonoscopy, it can really make a big change in your life," he said, per People. He added that since his diagnosis, he has heard from others who have gone for check-ups. "I have heard from so many people who have been inspired enough by my words and actions to say that they are going to check in with their doctors and get mammograms, a colonoscopy or a prostate exam," Coulier shared via Instagram in November 2024. "I'm still going to laugh in the face of adversity." John Stamos Promises to Be by Dave Coulier's Side Amid Cancer Battle His Prognosis Coulier expressed optimism about his recovery after a bone marrow test came back negative shortly after his diagnosis. "At that point, my chances of curable went from something low to [the] 90 percent range," he said. "And so that was a great day." Telling the Full House Cast Fotos International/Getty Images Coulier wanted to make sure his TV family, the cast of Full House, heard the news of his diagnosis from him. "I didn't want them to hear it from someone else, so I sent a text message out," Coulier said. "It was just this outpouring of, 'I will be there. You just name the time, and I know you're in great hands with [wife Melissa Bring], but what can we do? It really is overwhelming the love that we have for each other. We've been there for so many years for each other, and it's pretty remarkable."
