Study: Rise in Cancer linked to oral sex

The researchers reported that cancers of the tonsil and base of the tongue have been increasing every year since 1973, and wrote that “widespread oral sex practices among adolescents may be a contributing factor in this increase.”

The researchers concluded that in their study, oral sex was “strongly associated” with oropharyngeal cancer, but noted that they could not “rule out transmission through direct mouth-to-mouth contact” such as French kissing.
