Oral cavity and oropharyngeal cancers affect the mouth and throat. This year, the American Cancer Society predicts around 59,660 new cases of these types of cancers and about 12,770 deaths. No one can make themselves immune to cancer. However, recognizing that certain lifestyle habits can increase a person’s risk for these cancers may help them avoid behaviors that could increase their chances of being diagnosed with this disease.

  • Tobacco use. Smoking cigarettes, pipes, e-cigarettes, and using chewing tobacco or snuff can increase the risk for oral cancers. More research is needed, but evidence suggests that newer nicotine pouches may increase the risk of oral cancer.
  • Alcohol consumption. Heavy alcohol use increases the risk for oral cancers. Alcohol abuse, defined as drinking more than 21 standard drinks in one week, is the second largest risk factor for oral cancer, according to The Oral Cancer Foundation.
  • Age. The National Institute of Dental and Craniofacial Research says the risk of oral cancer increases with age, and most cases occur in people over age 40.
  • HPV virus. Research indicates that approximately 70% of cases of oropharyngeal cancer are caused by the human papillomavirus, particularly HPV16. The HPV16 virus is detectable in the tumors of these cancers.
  • Poor diet. A diet low in fruits and vegetables has been linked to increased risk of oral cancers.
  • Sun exposure. The American Cancer Society says oral cancers that begin on the lips can be caused by radiation from the sun.

Cancers of the mouth affect thousands of people across North America. Understanding which habits increase risk for oral cancers can help people do what’s necessary to potentially prevent their formation.
