Diseases of the Oral Cavity

Oral Cancer

Oral cancer includes cancers of the mouth and the pharynx (the back of the throat). Oral cancer accounts for roughly two percent of all cancers diagnosed annually in the United States. Approximately 35,000 people will be diagnosed with oral cancer each year and about 7,600 will die from the disease. On average, 60 percent of those with the disease will survive more than 5 years. Oral cancer most often occurs in people over the age of 40 and affects more than twice as many men as women.

What Puts Someone at Risk?

Tobacco and alcohol use. Most cases of oral cancer are linked to cigarette smoking, heavy alcohol use, or the use of both tobacco and alcohol together. Using tobacco plus alcohol poses a much greater risk than using either substance alone. HPV. Infection with the sexually transmitted human papillomavirus (specifically the HPV 16 type) has been linked to a subset of oral cancers. Age. Risk increases with age. Oral cancer most often occurs in people over the age of 40. Sun Exposure. Cancer of the lip can be caused by sun exposure. Diet. A diet low in fruits and vegetables may play a role in oral cancer development.

The exam is painless and takes only a few minutes. Your regular dental check-up is an excellent opportunity to have the exam. During the exam, your dentist or dental hygienist will check your face, neck, lips, and entire mouth for signs of cancer.
