Oral sex linked to mouth cancer: Swedish study
Certain cases of mouth cancer appear to be caused by a virus that can be contracted during oral sex.
People who contract a high-risk variety of the human papilloma virus, HPV, during oral sex are more likely to fall ill with mouth cancer, according to a study conducted at the Malmo University Faculty of Odontology in southern Sweden.
“You should avoid having oral sex,” dentist and researcher Kerstin Rosenquist, who headed the study, told Swedish news agency TT. HPV is a wart virus that causes many cervical cancers, including endometrial cancer (in the uterus).Comparing 132 patients with mouth cancer with a control group of 320 healthy people, Rosenquist found that 36 percent of the cancer patients were carriers of HPV while only one percent of the control group had the virus.
The main factors that contribute to mouth cancer, most commonly contracted by middle aged and older men, are smoking and drinking alcohol. “But in recent years the illness has been on the rise among young individuals and we don’t know why. But one could speculate that this virus (HPV) is one of the factors,” Rosenquist said.
Her findings confirm other international studies in recent years. 11/18/05
Something to think about: Human Papilloma Virus has been linked to 30-40% of oral cancers, I did a quick Google search which turned up several credible sources backing up the information, mostly linking HPV strains 16 & 18 to pharyngeal/tonsillar cancers. Yet, HPV vaccine is only covered by health insurance for 9 year old girls. The vaccine is a series of 3 injections each costing $150 (here in California). So the cost to a non 9-year-old-female would be $450.
Patients with pharyngeal & tonsillar warts may be reticent about removing them. (high risks of bleeding) The vaccine isn’t a cure for existing warts, but as time goes on and all people get vaccinated then maybe fewer oral cancers will arise. And maybe (sexual practices being what they are) the case for removing existing oral warts becomes more compelling, Dr. KB Dental Drugs Forum 8/06
