Dave Coulier Gives Candid Cancer Update: ‘In Fight or Flight Mode’

Full House star Dave Coulier has shared a candid update regarding his ongoing cancer treatment.

“The side effects have side effects,” Coulier, 65, said in the latest episode of his “Full House Rewind” podcast published on Friday, January 10. “And then you take a drug to counteract that and this and that. So it’s this constant cocktail where your body is in fight or flight mode and you’re just trying to adjust to, ‘Okay, how am I adjusting to steroids? How am I adjusting to the chemo cocktail?’”

Coulier went on to say that his body is in “a constant fight.”

“It’s a little bit of an internal battle,” he continued.

In November 2024, the actor revealed he had been diagnosed with Stage 3 non-Hodgkin lymphoma. In an interview with People, Coulier explained that he had first received his diagnosis in October the same year after experiencing an upper respiratory infection that resulted in severe swelling of his lymph nodes.

As a result, Coulier underwent PET and CT scans as well as a biopsy.

“Three days later, my doctors called me back and they said, ‘We wish we had better news for you, but you have non-Hodgkin’s lymphoma and it’s called B cell and it’s very aggressive,” Coulier told the outlet at the time. “I went from, ‘I got a little bit of a head cold’ to, ‘I have cancer’ and it was pretty overwhelming. This has been a really fast roller coaster ride of a journey.”

Non-Hodgkin lymphoma is a form of cancer that fights the body’s lymphatic system and affects “white blood cells called lymphocytes [that] grow abnormally and can form growths (tumors) throughout the body,” according to the Mayo Clinic.

After publicly revealing his diagnosis, Coulier explained that he and his wife Melissa Bring relied on the advice of friends working in the medical field to create “a very specific plan for how they were going to treat” his aggressive form of cancer.

“That was really a conscious decision of, I’m going to meet this head-one, and I want people to know it’s my life,” Coulier explained in a November 2024 episode of his podcast following his diagnosis reveal. “I’m not going to try and hide anything. I would rather talk about it and open the discussion and inspire people.”

In the Friday episode of his podcast, Coulier revealed that since sharing his diagnosis he has “heard from so many people who have been affected by cancer in their lives.”

“The words of encouragement have, I think, really helped people,” he shared. “So that, to me, is worth the journey of all of this. Just being able to alert people that it’s okay to get a colonoscopy or early screenings or a mammogram, it’s really worth it.”
