Dave Coulier was recently diagnosed with stage 3 non-Hodgkin lymphoma.

The Full House alum, 65, told People in an interview published on Wednesday, November 13, that he received his diagnosis in October after an upper respiratory infection resulted in severe swelling of his lymph nodes. After one area grew to the size of a golf ball, Coulier underwent PET and CT scans and 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,’” he told the outlet. “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.”

According to the Mayo Clinic, 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.”

Coulier said he and his wife, Melissa Bring, advised friends of theirs in the medical field and worked to create “a very specific plan for how they were going to treat this.” He noted that his recovery rate “went from something low to [the] 90 percent range” after a bone marrow test came back negative.

In addition to shaving his head and undergoing one round of chemotherapy thus far, Coulier revealed during a Wednesday appearance on Today that he’s had “three surgeries” If his treatment goes as planned, Coulier said he should be in “total remission” by the time he completes chemo in February 2025.

Coulier continued to open up about his cancer diagnosis on Wednesday’s episode of his “Full House Rewind” podcast, explaining that he was wearing a hat after choosing to shave his head. “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,” he shared. “I’m not going to try and hide anything. I would rather talk about it and open the discussion and inspire people.”
