Oral Cavity (Mouth) and Oropharyngeal (Throat) Cancer
There's no routine screening test or program for oral cavity and oropharyngeal cancers. Still, many pre-cancers and cancers in these areas can be found early (when they're small) during routine oral exams by a dentist, doctor, dental hygienist, or by self-exam.
Some dentists and doctors recommend that you look at your mouth in a mirror every month to check for any changes, like white patches (leukoplakia), sores, or lumps. This is very important if you use or have used tobacco, and/or if you routinely drink alcohol, as these put you at much higher risk for these cancers.
Regular dental check-ups that include an exam of the entire mouth are important in finding oral and oropharyngeal cancers (and pre-cancers) early.
Along with a clinical exam of the mouth and throat, some dentists and doctors may use special dyes and/or lights to look for abnormal areas, especially if you are at higher risk for these cancers. If an abnormal area is spotted, tests might also be used to help decide if they might be cancer (and need to be biopsied) or to choose the best spot to take tissue from for a biopsy. (See Tests for Oral Cavity and Oropharyngeal Cancers) Here are some of the tests used most often:
And even though HPV is a risk factor for oropharyngeal cancers, there is no approved test to screen for HPV in the throat like there is for cervical cancer.
