Causes of Oral Cancers Changing

Oral and pharyngeal squamous cell carcinomas have been associated with alcohol and tobacco use.  Recent studies suggest cancers of the back (base) of the tongue and tonsils are associated with high-risk HPV types.  While there has been a decrease in oral cavity cancer rates due to a decrease in smoking, there has been an increase in HPV associated cancers in the back of the throat.  Transmission by skin-to-skin contact during oral sex and open-mouthed kissing is the mode of infection.

It should be noted that oral cancers due to alcohol and tobacco are steadily declining but those due to HPV are increasing dramatically.
