Oral Cancer

Oral cancer is cancer of the mouth or throat. This year, an estimated 49,670 people will be diagnosed with oral cancer and more than 9,700 will die of the disease. Oral cancer is twice as common in men as in women.

Not using tobacco and not drinking alcohol in excess can prevent most oral cancer. However, one in four people diagnosed with oral cancer has no risk factors. It’s important to see your dentist regularly for screenings.

Risk Factors

You might be at increased risk for oral cancer if you:

  • Are older than 55
  • Chew or smoke tobacco
  • Drink alcohol in excess
  • Are exposed to sunlight for long periods of time
  • Have a certain type of human papillomavirus (HPV)
  • Have an immune system that has been weakened by certain medications
  • Have the skin disease lichen planus, graft-versus-host disease (GVHD) or certain inherited conditions of the blood


Don’t wait for oral cancer symptoms to appear. Get screened according to guidelines. If you do notice any of the following symptoms, talk with your health care professional.

  • White or red patches on lips, gum, tongue or mouth lining
  • A lump which can be felt inside the mouth or on the neck
  • Pain or difficulty chewing, swallowing or speaking
  • Hoarseness lasting a long time
  • Numbness or pain in any area of the mouth that doesn’t go away
  • Swelling of the jaw
  • Loosening of teeth
  • Difficulty wearing dentures
  • Bleeding in the mouth
  • A sore on the lips or in the mouth that doesn’t go away
  • An earache that doesn’t go away


Oral cancer is a highly preventable disease and also very treatable, if caught early.

  • Don’t use tobacco in any form. If you use tobacco, quit.
  • Limit alcohol to no more than one drink per day if you’re a woman or two drinks per day if you’re a man

  • Always use lip balm with SPF 30 or higher
  • Eat lots of fruits and vegetables

Early Detection
