Dave Coulier explains lasting impact of cancer treatment

Dave Coulier has lost 45lbs and his voice has changed as a result of his gruelling cancer treatment.

Dave Coulier’s cancer treatment has changed his voice.

The Full House actor was diagnosed with stage 3 non-Hogkin lymphoma in 2024 and months after getting the all-clear, was told he had HPV-related oropharyngeal tongue cancer, but revealed in February he is now in remission.

But Dave has now addressed fans concerns about changes to his appearance and voice and explained it is due to the effects of his treatment.

He said in a video shared to Instagram: “I haven’t posted in quite a while, and the last time I did some of you said that I look differently and I sound differently, and I do.

“What you’re seeing is the side effects of extensive radiation that I went through carcinoma in my throat.

“I haven’t been able to eat solid food in months, and so I’ve lost 45 pounds. That’s what you’re seeing, and it’s affected my ability to speak.

“Some of you said that I sound differently. So yeah, you’re right on with what you are seeing and what you hearing.”

Despite the changes, the 66-year-old actor is “very pleased” with the current state of his health.

He added: “But just to recap, a year and a half ago I had non-Hodgkin’s lymphoma and I went through chemotherapy, and my hair is kind of growing back. And we got our PET scans back, and the prognosis looks good for both the carcinoma in my throat and the lymphoma. So we’re very pleased with all of that.”

When he confirmed he was in remission, Dave admitted the last few years had been a “rollercoaster ride”.

During an appearance on Good Morning America, he said: “It’s been a rollercoaster ride for sure … I’m in remission with both cancers and what a journey this has been.

“Even though I’m in remission, I feel like cancer is always in the rear-view mirror … so early detection really means everything.”

Dave revealed the second cancer was discovered when he went for a check-up relating to his Lymphoma battle and he subsequently underwent robotic surgery to remove part of his tongue for a biopsy and it confirmed his diagnosis with a separate cancer.

He explained: “I was going in for a checkup for the lymphoma and got a PET scan and it revealed that something was in my throat and they said: ‘Uh, let’s take a look at this’ …

“And then it was revealed that I have carcinoma, and totally unrelated. Had I not gone in for that PET scan and gotten early detection … it saved my life.”

He then underwent a course of radiotherapy and he was determined to “laugh” his way through the gruelling treatment plan.

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. I was going to laugh my way through it and keep the people that I love close to me.”
