Effective measures for the primary prevention of oral cancer include tobacco cessation, alcohol cessation, HPV vaccine, and avoiding excessive sun exposure.
Based on solid evidence, cessation of exposure to tobacco (e.g., cigarettes, pipes, cigars, and smokeless tobacco) leads to a decrease in the risk of cancer of the oral cavity and oropharynx.
Based on fair evidence, cessation of alcohol consumption leads to a decrease in oral cavity cancer but not until approximately 10 years after cessation.
For cancer of the oropharynx, reduction in risk does not occur until approximately 20 years after cessation.
