In observation of Oral Cancer Awareness Month, we wanted to provide you with some information about the human papillomavirus (HPV) and oral cancer and the links between the two.

There are more than 40 types of HPV that can affect the mouth and throat areas, most of which congregate near the base of the tongue and tonsil area, known as the “oropharynx.” HPV is the most common sexually transmitted infection (STI) in the United States, but only HPV type 16 has been found in oropharyngeal cancer.

The human body typically fights off the HPV infection naturally, but the infection has the potential to turn regular cells in infected skin into irregular cells—sometimes irreversibly so. According to the U.S. Center for Disease Control, “about 7% of people have oral HPV,” and of that number, “only 1% of people have the type of oral HPV that is found in oropharyngeal cancers.”
