Screening check
Should I get screened for oral (mouth) cancer?
In the US, up to 3 in 4 mouth cancers may be due to tobacco and alcohol. The US Preventive Services Task Force looked at whether adults with no symptoms should have a mouth exam by their primary care clinician. Check what it says for you.

What the USPSTF says about oral cancer screening for you.
Educational only, not medical advice. This is not a mouth exam. Show any lasting change to a clinician or dentist.
Source
US Preventive Services Task Force, November 2013 recommendation on screening for oral cancer. A July 2023 literature scan found no new evidence to update it.
Validated in
Adults 18 and older without symptoms, seen in primary care.
Limits
It is not a mouth exam and cannot tell whether a spot is cancer. The advice is for primary care clinicians, not dentists or ear, nose and throat specialists.
What the USPSTF recommends
| Who | Recommendation | Grade |
|---|---|---|
| Adults 18 and older without symptoms | Evidence is insufficient to weigh the benefits and harms of screening for oral cancer | I |
Screening here means a primary care clinician looking at and feeling the inside of the mouth. The recommendation does not apply to dentists or ear, nose and throat specialists, who may examine the mouth and throat during a visit (USPSTF 2013). In 2023 the USPSTF found no new evidence to justify an update (USPSTF 2013).
Why it matters
In the US, up to 75% of oral cancers may be due to tobacco and alcohol use (USPSTF 2013). Nearly three fourths of oral and throat cancers occur in men. More than half of people already have spread to nearby lymph nodes or further at diagnosis, and five-year survival falls from 82.4% when the cancer is localized to 33.2% once it has spread to distant sites (USPSTF 2013).
Why the evidence falls short
There was inadequate evidence on how accurately the exam finds oral cancer and no direct evidence that screening lowers illness or death in the US (USPSTF 2013). The one large trial, of home screening in Kerala, India, found no significant drop in oral cancer deaths overall. A later analysis of people who used tobacco or alcohol suggested a benefit, but it had methodological problems and limited relevance to the US, partly because many participants chewed paan (USPSTF 2013). A suspicious spot needs a biopsy, and treatment can cause harms; how often screening leads to overdiagnosis is unknown (USPSTF 2013).
Common questions
What raises the risk?
Tobacco and alcohol use are the main risk factors. Others include male sex, older age, chewing betel quid, UV light exposure, infection with Candida or bacteria, and a weakened immune system (USPSTF 2013).
What about HPV?
Sexually transmitted oral HPV infection, mainly HPV-16, is an increasingly important cause of cancer of the oropharynx (the back of the mouth and throat). No FDA-approved test screens for oral HPV, and medical and dental groups do not recommend testing for it (USPSTF 2013).
What does an oral cancer exam involve?
A look at the face, neck, lips, the inside of the cheeks, the gums, the floor of the mouth, the tongue and the palate, plus feeling the lymph nodes, tongue and floor of the mouth. Any change that lasts more than 2 weeks should be checked again and considered for a biopsy (USPSTF 2013).
