We all know that tobacco and alcohol use puts people at an increased risk for developing oral cancer. Recent studies have identified another risk factor to consider. It is the infection of the oral tissue by the human papilloma virus (HPV) through sexual contact. In the past, studies indicated 75 percent of diagnosed oral cancer cases had used some form of tobacco. Research identifying HPV in the tissue of oral malignancies gives new clues as to the origin of oral cancer in those 25 percent of individuals with no history of tobacco use.
The Oral Cancer Foundation predicts that the 75 percent of “tobacco-related” to 25 percent of “other causes” ratio is no longer accurate and is outdated. New studies being published suggest HPV as an equal, if not more important, cause of oral cancer than tobacco use. HPV’s impact will certainly be a significantly larger percent and is estimated to be in the range of 50-65 percent.
The American Dental Association Council on Scientific Affairs states: “Risk factors for oral cancers have typically been older age, use of tobacco and excessive alcohol consumption. However, based on available evidence, oral HPV infection is now considered an important risk factor for oral cancers in both men and women, even in the absence of tobacco and alcohol use.” Studies further suggest HPV oral cancer incidence is three times higher among men than women, higher in younger adults and in people with a higher lifetime number of sexual partners.
With another risk factor recognized, it is now more important to have an annual oral cancer screening. This can be conveniently accomplished by a dentist or dental hygienist during your annual appointment. During this routine visit, your dentist should examine the oral soft tissue and identify any suspicious lesions. The dentist may perform or refer the patient for a biopsy to determine a definitive diagnosis. Your dentist should provide advice and guidance regarding the known risks for oral cancer from smoking, heavy alcohol use and HPV infection. This is especially important with the increased incidence of oral cancer in younger, non-smokers and non-drinkers.
It is worth mentioning that the new vaccines approved for pre-sexual individuals to target HPV infection for the prevention of cervical cancer will likely have a positive impact on future oral cancer rates. The Oral Cancer Foundation believes the elimination of the HPV virus by preventing infection with a vaccine will subsequently prevent any disease HPV may produce in a protected individual. This view is shared by many in the scientific community.
Prevention and early detection of oral cancer. Something to think about.
