American comedian Dave Coulier’s announcement that he has been diagnosed with early-stage P16 tongue and oropharyngeal cancer has renewed public attention to this serious condition, which typically develops at the base of the tongue and is strongly associated with human papillomavirus (HPV).
Coulier had previously revealed his recovery from non-Hodgkin lymphoma, but follow-up scans detected a new tumor in his tongue.

According to medical experts, tongue cancer may affect the front part of the tongue or its base, and risk factors vary depending on the tumor’s location. In 2025, an estimated 20,000 new cases of tongue cancer were expected in the United States, rising to nearly 59,000 when including all oral and oropharyngeal cancers. The five-year survival rate stands at approximately 71%.

The increased incidence is strongly linked to rising HPV infection rates, and when the tumor is HPV-related, recovery rates can reach 80–90%.

Early warning signs include:

• Persistent tongue sores

• Pain or difficulty swallowing

• A palpable lump on the tongue

• Speech changes

• Unexplained oral bleeding

Experts emphasize that symptoms lasting more than two weeks should be evaluated by a specialist, as early detection significantly improves recovery outcomes. When the disease spreads, additional signs may appear, such as a neck mass due to enlarged lymph nodes, ear pain, or jaw stiffness.

Major risk factors include smoking, excessive alcohol consumption, HPV infection, poor oral hygiene, and weakened immunity.

Treatment varies based on the cancer stage and commonly includes surgery and radiation therapy, while advanced cases may require chemotherapy or targeted therapies. Doctors increasingly rely on minimally invasive techniques to preserve speech and swallowing functions.

Specialists urge the public to pay close attention to any changes within the mouth, maintain regular dental checkups, and consider HPV vaccination to reduce future risks.
