Oral sex responisble for multiple types of cancerIn addition to throat cancer, the HPV virus is sometimes responsible for head and neck cancer as well. Of course, there's one easy way to have the HPV virus affect your head, neck or throat, and that would be performing oral sex on somebody. Having more than three oral-sex partners over the course of your life greatly increases the risk of getting cancer, so get a vaccine against the virus if you still can. (PDN)
