Oral cancer screenings are routine for your dentist. They have been trained to spot even the slightest symptoms. Screenings begin with a visual inspection of your mouth. Your dentist will look at the tissue on your inner cheeks, under your tongue and the sides of your tongue. He will feel around your jaw and look for any hard lumps that could signal a tumor.
If your dentist spots leukoplakia (an abnormal white patch of cells) or erythroplakia (an abnormal red patch of cells), he or she will be able to use tests to further investigate if the cells are, or could be, cancerous. The three most commonly used oral cancer diagnostic tests are:
- Toluidine blue stain: The lesions in the mouth are coated with a blue dye. Areas that stain darker are more likely to be cancerous or become cancerous.
- Fluorescence staining: The lesions in the mouth are viewed using a special light. After the patient uses a fluorescent mouth rinse, normal tissue looks different from abnormal tissue when seen under the light.
- Exfoliative cytology: A stiff brush (brush biopsy) is used to gently scrape cells from the lips, tongue, mouth or throat. The cells are viewed under a microscope to find out if they are abnormal.
The earlier your dentist finds cancerous cells, the less likely it is that the cancer will spread to other parts of your body. Be proactive when it comes to your health. You will be glad you did!
