Oral Cancer Screening: Responsibility and Opportunity in the Dental Visit
Approximately 54,000 Americans are diagnosed with oral cavity or oropharyngeal cancer each year, and the five-year survival rate drops dramatically when diagnosis is delayed beyond Stage I or II. Dentists are often the first — or only — healthcare provider to perform a systematic head-and-neck examination, making them uniquely positioned to detect early-stage oral lesions. How do you think about the oral cancer screening responsibility that every dental visit represents, and what should a dentist do when a patient is reluctant to have a tissue biopsy recommended after an abnormal finding?
Likely follow-up · HPV-associated oropharyngeal cancers have surpassed tobacco-associated oral cancers in incidence in the United States. How does this epidemiological shift change what you ask patients about during a health history intake?
