An oral cancer screening is a visual and physical check of areas such as the face, neck, lips, mouth and back of the throat for signs that may need further evaluation. The National Institute of Dental and Craniofacial Research (NIDCR) says a regular dental checkup is an opportunity for this exam, which is painless and takes only a few minutes. A screening looks for possible signs; it does not by itself diagnose cancer.
What happens during an oral cancer screening?
A dentist or dental hygienist checks the face and neck, lips and mouth, then looks at the back of the throat. The exam can include looking at the tongue, gums and other mouth tissues for changes such as a sore, lump, thickened area, or red or white patch. The clinician may also feel parts of the face and neck for unusual areas.
If something appears unusual, the next step may be additional tests or a referral for further evaluation. An unusual finding is not the same as a cancer diagnosis; screening identifies signs that may need follow-up.
Why screening and follow-up matter
Oral cancers can affect the mouth and the back of the throat. NIDCR notes that early detection is important because oral cancer can spread quickly. Screening is one way to look for possible signs during a routine dental visit, but it cannot guarantee that cancer will be found or ruled out.
NIDCR advises seeing a dentist or doctor if symptoms such as a mouth sore, red or white patch, persistent sore throat, hoarseness, neck lump, difficulty swallowing, or numbness in the mouth last more than two weeks. This general guidance is not a diagnosis; a dental or medical professional can assess an individual concern.
