Oral Cancer Update

In their latest issue, The Journal of the American Dental Association features multiple articles about the connection between human papilloma virus (HPV) and oral cancer. HPV has been recognized as a significant factor in contracting certain forms of oral cancer.

Cancers in the back of the throat, around the tongue and tonsils are the most common cancers caused by HPV. According to literature reviews, HPV-positive cancers have a lower incidence of death and recurrence as compared to HPV-negative cancers.

HPV has been most commonly associated with cervcial cancers, and several vaccines against that form of HPV, as well as other HPV types, has been available for several years. However, the types of HPV associated with oral cancers have no effective vaccine at this time. Currently, there is no test for detecting HPV infection. Prevention of HPV infection is the best approach to reducing oral cancer risk.

Oral HPV is thought to be acquired during oral sex, and also passed on by kissing. More research is needed to clarify the specific means of transmission.

Even though preventing HPV infection is effective at reducing the risk of oral cancers, it is also important to understand that tobacco and alcohol are significant risk factors in contracting oral cancer. About 75% of all oral cancers are related to smoking and alcohol use.

Cascadia Dentistry has been using the most effective oral cancer screening tools available for the past 2 years. The Identafi 3000 is a tool that uses visible light to detect abnormal oral tissue. It is valuable in early detection of oral cancers, and can help patients seek treatment earlier, and in many cases help them avoid more significant treatment. Detecting cancers earlier can reduce deaths in many cases.
