Oral sex can lead to oral tumors…
…. according to a US study published in the New Scientist. The human papilloma virus (HPV) is an extremely common sexually transmitted infection that has been known to cause cervical cancers. However, studies have suggested it also plays a role in other cancers, including oral cancer. Out of those, 1,670 people had oral cancer, the people with oral cancers containing the HPV16 strain the most commonly seen strain in cervical cancer were three times as likely to report having had oral sex . We have known for some time that there is a small but significant group of people with oral cancer whose disease cannot be blamed on decades of smoking and drinking, because they’re too young. In this group there must be another factor, and HPV and oral sex seems to be one likely explanation. 3/04
