Cancer shows that having a large number of oral sex partners leads to a higher risk of contracting HPV-related cancer of the mouth and throat.The study, done by a team of researchers at Johns Hopkins University, surveyed over 500 people about their sexual activity.
One third of participants had been diagnosed with human papillomavirus (HPV) and about two-thirds had not.According to the study, those who have had 10 or more prior oral sex partners have a 4.3 times higher likelihood of getting HPV-related cancer of the throat or mouth.
