Cigarette smokers are also more likely than nonsmokers to develop several other types of cancer, including oral cancer and cancers of the larynx, esophagus, pancreas, bladder, kidney, and cervix. Smoking may also increase the likelihood of developing cancers of the stomach, liver, prostate, colon, and rectum. The risk of cancer begins to decrease soon after a smoker quits, and the risk continues to decline gradually each year after quitting.

People who smoke cigars or pipes have a risk for cancers of the oral cavity that is similar to the risk for people who smoke cigarettes.

The use of smokeless tobacco (chewing tobacco and snuff) causes cancer of the mouth and throat. Precancerous conditions, tissue changes that may lead to cancer, often begin to go away after a person stops using smokeless tobacco.

What You Need To Know About Oral Cancer: NCI (Excerpt)

Two known causes of oral cancer are tobacco and alcohol use.

Tobacco use -- smoking cigarettes, cigars, or pipes; chewing tobacco; or dipping snuff -- accounts for 80 to 90 percent of oral cancers. A number of studies have shown that cigar and pipe smokers have the same risk as cigarette smokers. Studies indicate that smokeless tobacco users are at particular risk of developing oral cancer. For long-time users, the risk is much greater, making the use of snuff or chewing tobacco among young people a special concern.

People who stop using tobacco -- even after many years of use -- can greatly reduce their risk of oral cancer. Special counseling or self-help groups may be useful for those who are trying to give up tobacco. Some hospitals have groups for people who want to quit. Also, the Cancer Information Service and the American Cancer Society may have information about groups in local areas to help people quit using tobacco.

Chronic and/or heavy use of alcohol also increases the risk of oral cancer, even for people who do not use tobacco. However, people who use both alcohol and tobacco have an especially high risk of oral cancer. Scientists believe that these substances increase each other's harmful effects.

Cancer of the lip can be caused by exposure to the sun. The risk can be avoided with the use of a lotion or lip balm containing a sunscreen. Wearing a hat with a brim can also block the sun's harmful rays. Pipe smokers are especially prone to cancer of the lip.

Some studies have shown that many people who develop oral cancer have a history of leukoplakia , a whitish patch inside the mouth. The causes of leukoplakia are not well understood, but it is commonly associated with heavy use of tobacco and alcohol. The condition often occurs in irritated areas, such as the gums and mouth lining of smokeless tobacco users and the lower lip of pipe smokers.

Another condition, erythroplakia , appears as a red patch in the mouth. Erythroplakia occurs most often in people 60 to 70 years of age. Early diagnosis and treatment of leukoplakia and erythroplakia are important because cancer may develop in these patches. (Source: excerpt from What You Need To Know About Oral Cancer: NCI)

About risk factors:

Risk factors for Oral cancer are factors that do not seem to be a direct cause of the disease, but seem to be associated in some way. Having a risk factor for Oral cancer makes the chances of getting a condition higher but does not always lead to Oral cancer. Also, the absence of any risk factors or having a protective factor does not necessarily guard you against getting Oral cancer. For general information and a list of risk factors, see the risk center.
