Early detection
Did you know that every day, every hour one American dies of oral cancer? With an estimated 30,000 Americans diagnosed each year, oral cancer has a higher mortality rate than cervical cancer, Hodgkin’s disease, liver cancer, and kidney cancer. When found early, oral cancer has a 90 percent cure rate, therefore, early detection is critical. You are at increased risk for oral cancer if you use tobacco in any form, consume heavy amounts of alcohol combined with smoking, are over age 40, and/or have prolonged exposure to the sun (lip cancer). Human papillomavirus (HPV) exposure is a new oral cancer risk factor. HPV is the cause of the fastest growing oral cancer for people under the age of 45.

Early Detection is Key

Because 25 percent of the people diagnosed with oral cancer have no risk factors, an oral cancer screening should be a routine part of dental maintenance. Regular check-ups, including an examination of the entire mouth, are essential in the early detection of cancerous and pre-cancerous conditions. Common symptoms of oral cancer or pre-cancerous cells include:

  • A change in the way the teeth fit together
  • A color change in the oral tissues
  • A tiny white or red spot/sore anywhere in the mouth
  • Any sore that bleeds easily or refuses to heal
  • Difficulty chewing, swallowing, speaking or moving the jaw or tongue
  • Lumps, thickenings, rough spots, or crusty areas
  • Pain, tenderness, or numbness anywhere in the mouth or on the lips

Screening for Oral Cancer
During an oral cancer exam, your dentist will carefully examine the tongue, inside of your mouth, and your lips to look for spots or sores that are flat, painless, white, or red. Many of these spots or sores are harmless, but some aren’t so you will likely need a test to determine if a problem exists. Your dentist may choose to perform a brush test, which involves scraping a miniature brush across the suspicious sore or discolored area in the patient’s mouth. The cells collected on the brush are sent to a lab for analysis. If the results show suspicious cells are present, a biopsy can then be performed.

Common Questions

I don’t drink or smoke. Why do I need an oral cancer screening?
Even though certain elements, like lifestyle, age, and heredity, can play a role in your risk for developing oral cancer, people with no known factors can still develop oral cancer. Routine checkups and screenings allow your dentist to catch problems before they escalate.

I noticed a few small sores in my mouth. Should I be worried?
If you notice any unusual spots, sores, discolorations or bumps in your mouth, you should contact your dentist right away. Oral cancer treatment is very successful when the cancer is detected early.

Does an oral cancer screening hurt?
No. During the initial exam, your dentist will look inside your mouth, checking the gums, lips, and other soft tissue for any strange spots or sores. In some cases, the doctor may use special equipment such as Oral ID to highlight any areas of concern. If an area looks suspicious, the doctor can perform a brush test, gently scraping cells to be sent off to the lab for further assessment.
