New Webpage on Bumps or Lesions of the Mouth

Our practice has created a new webpage describing the various bumps and lesions commonly seen in the mouth that leads to a doctor's visit.

Such abnormal things seen in the mouth that's discussed include:

• aphthous ulcer


• herpetic ulcers


• pyogenic granuloma

Oral Sex Causes More Oral Cancer Than Smoking!

HPV may now be overtaking tobacco as the leading cause of oral cancers in America in people under age 50.

And HPV, otherwise known as Human Papilloma Virus responsible for gential warts and cervical cancer, finds it way into the mouth via oral sex.

The latest data suggest that 64% of oral cancers are caused by HPV, which is more than tobacco causes. Furthermore, as the number of partners on whom you have performed oral sex goes up, the risk of oral cancer goes up.

These findings were presented by scientists this past Sunday at the American Association for the Advancement of Science annual meeting.

Hopefully, these results will be formally published soon, but you can read the story on CNN for now here.

Link Between Oral Sex and Head & Neck Cancer

USA Today published a pretty accurate article regarding the rise of certain head & neck cancers with the increased popularity of oral sex and number of sexual partners.

The factor that creates this link is the HPV virus which is associated with tonsil and tongue cancer. Alcohol and tobacco use is more highly linked with such oral cancers, but HPV does appear to be an independent risk factor.

A 2007 study in the New England Journal of Medicine found that younger people with head and neck cancers who tested positive for oral HPV infection were more likely to have had multiple vaginal and oral sex partners in their lifetime. Having six or more oral sex partners over a lifetime was associated with a 3.4 times higher risk for oropharyngeal cancer; cancers of the base of the tongue, back of the throat, or tonsils. Having 26 or more vaginal-sex partners tripled the risk. The association continued to increase as the number of partners in either category increased.

Of greater concern is that "French" kissing may also potentially be a mode of transmission.

The good news (if one is a young, non-smoker diagnosed with HPV-positive tumors) is that about 85% of non-smoking people with HPV-positive tumors survive. That number drops to 45 or 50% in people who smoke and are HPV-negative.

Th take-home message here is that even if you are a non-smoker and non-drinker, you can STILL develop head and neck cancer. Oral HPV infection is strongly associated with oropharyngeal cancer among subjects with or without the established risk factors of tobacco and alcohol use and that oral HPV infection can occur through sexual activity.

Furthermore, it is possible that the HPV vaccine (ie, gardasil) may also be protective (studies pending) for both women AND men.
