Human papillomavirus (HPV) is responsible for more than 5% of all cancers, including all cervical cancers. Presently, an estimated 63% of oropharyngeal cancers are caused by HPV, and tha percentage is rising. At current rates, oropharyngeal cancer will become the leading HPV-related cancer in the United States by the year 2020, surpassing the yearly number of cervical cancers. An estimated 7,400 new cases of HPV-related oropharyngeal cancers are diagnosed annually. These cases are highest among adults in their late 20's and late 50's. Men outnumber women 4:1. These cancers are most commonly found on the tonsils. Others are found at the base of the tongue. In these areas, diagnosis is usually at advanced stages (75% stage III/IV), with lymph node involvement.
While the prevalence of HPV infection is about 7% in the general population, it can be as high as 20% for those with more that 20 lifetime sex partners (oral, anal, and/or vaginal) or who smoke more than 20 cigarettes daily.
