7 Months Post-Lymphoma, ‘Full House’ star Dave Coulier Diagnosed With Early-Stage Tongue Cancer

Dave Coulier, the funny guy from Full House who played Uncle Joey, just shared tough news. At 66, he's facing tongue cancer. This comes only seven months after he beat stage 3 non-Hodgkin lymphoma. The actor revealed that he has been diagnosed with early-stage tongue cancer. 

Coulier shared his story in a recent interview, explaining that while he was relieved to have overcome one cancer, he did not expect to face another health challenge so soon. His announcement has sparked new conversations about early detection, recurring cancers, and the importance of staying alert to symptoms even after successful treatment.

Sharing the news publicly, Coulier said he noticed something unusual on his tongue during a routine self-check. According to reports, he explained that the spot “didn’t look right,” which pushed him to see his doctor. That appointment led to a biopsy, where specialists confirmed that it was early-stage tongue cancer.

He said the tongue cancer diagnosis came as a shock, especially after feeling hopeful post-lymphoma. Still, Coulier mentioned that he is focusing on staying positive. He added that early detection gave him a better chance of successful treatment and encouraged others to “never ignore small symptoms.” His comments reflect the reality that many cancer survivors face, being vigilant even when they think the worst is behind them.

According to the World Health Organization (WHO), cancers of the lip and oral cavity, which include tongue cancer, are among the most common head and neck cancers globally. The WHO notes that tobacco use, alcohol consumption, and HPV infection are major risk factors, and early detection plays a key role in improving survival rates.

Back in November 2024, Coulier faced stage 3 non-Hodgkin lymphoma. This cancer hits the lymphatic system with rogue white blood cells. He shared his story openly. Chemo drained him hard. By March 2025, scans showed he was cancer-free. "The previous year was particularly challenging," he reflected. Routine check-ups kept him going. That clean bill led to the October PET scan, spotting the tongue issue. Two biopsies nailed the new diagnosis.

Here’s a quick overview of what he experienced:

• Diagnosis: He was diagnosed with lymphoma a little over a year ago.
• Treatment: Reports note he underwent treatment that included targeted therapies and regular medical monitoring.
• Recovery: About seven months ago, he shared that he was officially in remission.
• Mental and physical strain: Coulier previously spoke about how the diagnosis changed his perspective on life, making him more mindful of health and family.

His resilience during that period earned him support from fans and the cancer community. Many people admired how he handled the emotional and physical toll while keeping a hopeful outlook.
