HPV Linked to Some Oropharyngeal Cancers
Posted in Health Buzz | No Comments »A recent study offers more evidence that “high risk” HPV types have a role in the development of some types of head and neck cancers and suggests the risk is higher as the number of lifetime oral sex partners increases.
Head and neck cancers include those of the oral cavity, and most HPV-related head and neck cancers are of the oropharynx (tongue, soft palate, and tonsils). The American Cancer Society estimates there are about 34,000 cases of oropharyngeal cancer each year in the U.S. Heavy tobacco and alcohol use is strongly linked to these diseases, but “high risk” HPV is also thought to play a role with some cases.
Research published in the May 10, 2007 issue of the New England Journal of Medicine found HPV 16 DNA present in 72% of tumors taken from patients with oropharyngeal cancer. Additionally, 57% of cancer patients were seropositive for HPV 16 antibodies, compared to 7% of the control group. The results also indicate sexual behavior might play a role in oropharyngeal cancers: 42% of cancer patients said they have had six or more lifetime oral sex partners, compared with 26% of control patients. Other risk factors for oropharyngeal cancer included a family history of head and neck cancer and poor oral hygiene. Heavy use of tobacco, alcohol, and marijuana were also associated.
Studies such as this inevitably lead some partners of those diagnosed with HPV to wonder if it’s safe to engage in oral sex. It should be pointed out that the vast majority of cases of HPV don’t lead to cancer, and cancers of the oropharynx are not common and don’t develop quickly: in the article’s discussion the authors note that “exposure to HPV can precede the appearance of oropharyngeal cancer by 10 years or more.”
There are few guidelines regarding oral sex and HPV, apart from common sense precautions of abstaining while skin lesions related to the virus are present (including cervical cell changes detected on Pap tests). The effectiveness of latex barriers (condoms or dental dams) in reducing oral HPV transmission hasn’t been studied, but some experts say they have value in protecting against other STIs when performing oral sex and may also reduce the risk of acquiring HPV.

So I told one of my best friends of five years that I had genital herpes.
