Major Forms of Cancer - Oral cancer



Cancers of the mouth and lips strike an estimated 24,000 persons in the United States each year and kill a shocking 8,500. Shocking because anyone with the aid of a mirror and a good light can see into his mouth and therefore spot even very small cancers early in their development.

Symptoms

Any sore, lump, or lesion of the mouth or lips should be regarded as suspicious if it persists more than two weeks without healing, and a physician or dentist should then be consulted without delay. The five-year survival rate for localized mouth cancers—when they are usually no larger than the little fingernail—is 67 percent—about two out of three. But if regional involvement occurs, the rate falls to 30 percent—fewer than one out of three.

Detection

Just as the Pap test screens for cervical cancer by scraping up sloughed-off cells that are then examined under a microscope, so one day your dentist may routinely scrape mouth cells to detect oral cancer. When more than 40,000 patients were screened over a five-and-one-half-year period at the Western Tennessee Cancer Clinic, about 230 cases of oral cancer were diagnosed, of which 35 percent would have been missed otherwise.

Right now, a weekly or monthly personal inspection of your mouth is the best detective method available. The American Cancer Society has materials explaining the best way to conduct such an examination.

Therapy

Oral cancers are treated by surgical removal or by irradiation.

Causes

No one can pinpoint the causes of oral cancer definitely, but there are a number of leading suspects. They are smoking, in all its forms; exposure to wind and sun (for lip cancer); poor mouth hygiene; sharp or rough-edged teeth or improperly fitted, irritating dentures; dietary inadequacies, and constant consumption of alcohol or very hot foods and liquids.
