oral cancer screening in pasadena

Why oral cancer screening?

Many pre-cancers and cancers of the oral cavity and oropharynx can be found early, during routine screening exams by a dentist, doctor, dental hygienist, or by self-exam.

Early Oral Cancer symptoms

Some early cancers have symptoms that cause patients to seek medical or dental attention.

Unfortunately, some cancers may not cause symptoms until they’ve reached an advanced stage, or they may cause symptoms similar to those caused by a disease other than cancer, such as a toothache.

Some dentists and doctors recommend that you look at your mouth in a mirror every month to check for any abnormal areas.

Importance of regular dental checkups

Regular dental checkups that include an exam of the entire mouth are important in finding oral and oropharyngeal cancers (and pre-cancers) early.

The American Cancer Society also recommends that doctors examine the mouth and throat as part of a routine cancer-related checkup.

Oral Cancer Screening Procedure

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, some of these tests may also be used to help determine if they might be cancers (and therefore will need a biopsy) or to choose the best area to sample for a biopsy.

  • One method uses a dye called toluidine blue. If the dye is spread over an abnormal area, it will stain blue.

 

  • Another method uses laser light. When the light is reflected off abnormal tissue, it looks different from the light reflected off normal tissue.

 

  • Another system uses a special light to view the area after the mouth has been rinsed with a solution of acetic acid (the acid in vinegar).

 

  • If an abnormal area is found, sometimes it can be evaluated by exfoliative cytology. In this technique, the lesion is scraped with a stiff brush (brush biopsy), and the cells from the scraping can be looked at under the microscope.
