What is oral cancer?
Oral cancer starts in the cells of the mouth (oral cavity). The oral cavity is made up of many parts:

• lips
   
• tongue
   
• inside of the lips and cheeks
   
• hard palate (roof of the mouth)
   
• floor of the mouth (under the tongue)
   
• gums and teeth

How is oral cancer diagnosed?
Your dentist will conduct an oral cancer screening exam, which is a routine part of a comprehensive dental examination. More specifically, your dentist will feel for any lumps or irregular tissue changes in your neck, head, face, and oral cavity. When examining your mouth, your dentist will look for any sores or discolored tissue, as well as check for or ask you about the signs and symptoms mentioned above.

Your dentist might perform an oral brush biopsy if he or she sees tissue in your mouth that looks suspicious. This test is painless and involves taking a small sample of the tissue and analyzing it for abnormal cells. Alternatively, if the tissue looks even more suspicious, your dentist might recommend a scalpel biopsy. This procedure usually requires local anesthesia and might be performed by your dentist or a specialist referred by your dentist. These tests are necessary to detect oral cancer early, before it has had a chance to progress and spread.

How is oral cancer treated?
Oral cancer is treated the same way many other cancers are treated; that is with surgery to remove the cancerous growth followed by radiation therapy and/or chemotherapy (drug treatments) to destroy any remaining cancer cells.

What can I do to prevent oral cancer?
You can take an active role in preventing oral cancer or detecting it early, should it occur.

• Conduct a self exam at least once a month. Using a bright light and a mirror, look and feel your lips and front of your gums. Tilt your head back and look at and feel the roof of your mouth. Pull your checks out to view the inside of your mouth, the lining of your cheeks, and the back gums. Pull out your tongue and look at all surfaces. Examine the floor of your mouth. Look at the back of your throat. Feel for lumps or enlarged lymph nodes in both sides of your neck and under your lower jaw. Call your dentist’s office immediately if you notice any changes in the appearance of your mouth or any of the signs and symptoms mentioned above.
   

• See your dentist on a regular schedule. Even though you might be conducting frequent self exams, sometimes dangerous spots or sores in the mouth can be very tiny and difficult to see on your own. The American Cancer Society recommends oral cancer screening exams every three years for people over age 20 and annually for those over age 40. During your next dental appointment, ask your dentist to perform an oral exam. Early detection can improve the chance of successful treatment.
   

• Don’t smoke or use any tobacco products and drink alcohol in moderation. (Refrain from binge drinking.)
   

• Eat a well balanced diet.
   

• Limit your exposure to the sun. Repeated exposure increases the risk of cancer on the lip, especially the lower lip. When in the sun, use UV-A/B-blocking sun protective lotions on your skin as well as your lips.
