Dave Coulier has revealed that he is cancer-free once again.

The Full House actor announced on World Cancer Day that he is officially in remission following aggressive treatment for tongue cancer.

“It’s been a roller coaster ride for sure,” Coulier said during an appearance on Good Morning America. “I’m in remission with both cancers. And what a journey this has been.”

Coulier first went public with his tongue cancer diagnosis in December months after doctors had cleared him of lymphoma.

During a routine six-month follow-up appointment and PET scan doctors noticed an abnormal flare-up where his tongue meets his throat.

Further testing revealed p16 squamous cell carcinoma a form of head and neck cancer.

Coulier later told PEOPLE that he was “in shock” by the diagnosis and initially believed the tumour was linked to his previous cancer.

Doctors confirmed the two cancers were unrelated.

“It turns out, if I hadn’t had that PET scan, then they wouldn’t have had this early of a detection and I’d have been in a world of pain soon,” Coulier said at the time.

“So as weird as this sounds, I’m now actually thankful for the first cancer, because it helped me detect this second one.”

Speaking to Good Morning America Coulier explained that radiation therapy brought its own challenges.

“[Radiation] has totally different side effects,” he said. “It can steal parts of your life away from you, psychologically, emotionally and certainly physically. And I wasn’t going to allow cancer to do that.”

Now in remission Coulier says he feels a responsibility to use his experience to encourage others to prioritise early detection and routine health screenings.

“I feel as though I can help people,” he said. “I never wanted to be the poster boy for cancer, believe me. But now I feel like I can encourage people to get those prostate exams and mammograms. Talk to your doctors and get ahead of this.”

He added that even with remission the experience stays with him.

“Even though I’m in remission, I feel like cancer’s always in the rear-view mirror behind me,” Coulier said. “‘Ehh, you trying to pass me here?’ So early detection really means everything.”
