Well, on the upside, we also have to worry about genetics, family history of cancer, alcohol, human papillomavirus, ultraviolet light, vitamin A deficiency and immune system suppression. Or, living in general.

Causes of Carcinoma Of The Oropharynx
There are a number of factors that present risks for developing oral and oropharyngeal cancer. These include tobacco, alcohol, human papillomavirus, ultraviolet light, vitamin A deficiency and immune system suppression.
Smoking or chewing tobacco is the greatest risk factor for developing oral cancer. The risk increases the longer a tobacco habit persists. These individuals may frequently develop other cancers involving the lung, head and neck. Pipe smoking carries a significant risk for cancers in the part of the lips that contact the pipe-stem. Chewing tobacco is associated with cancers of the cheek, gums and inner surface of the lips.
About 75 to 80 percent of all patients with oral cancer consume alcohol frequently, and oral and oropharyngeal cancers are about six times more common in drinkers than in nondrinkers. People who smoke and drink alcohol have a much higher risk of cancer than those using alcohol or tobacco alone. It is likely that these substances either directly or indirectly damage the DNA of the epithelial cells.
Human papilloma virus may contribute to the development
of some oral cavity and oropharyngeal cancers. This is especially true in individuals who have other risk factors.
More than 30 percent of patients with cancers of the lip have occupations associated with prolonged sunlight exposure. Many of these patients are fair-skinned with light hair and blue eyes.
Vitamin A deficiency is associated with an increased risk of developing cancer of the oral cavity and oropharynx. People taking immunosuppressive drugs to treat immune-system diseases or to prevent rejection of transplanted organs may be at increased risk for cancers of the oral cavity and oropharynx.
Here’s the rest of the depressing article. Remember, tobacco, alcohol, human papillomavirus, ultraviolet light, vitamin A deficiency and immune system suppression. And the oddly missing genetics and/or family history of cancer. Pretty much life in general unless you live in a cave. Kiss your ass goodbye, and bid farewell with a pipe and a blindfold.
