virus puzzleMichael Douglas is a well known actor, and his fight with head & neck cancer has been the subject of much public attention.   Adding to that attention this week, he mentioned that his cancer was caused by HPV (Human Papilloma Virus) and as such has a very good prognosis.  In addition, he noted the connection between exposure of this virus and sexual activity, particularly oral sex.

This connection has been well-documented and is often presumed to be the exposure that adds the final element in causing those head & neck cancers that have the HPV genetics expressed in the cancer tissue.  That said, the traditional risk factors of tobacco and alcohol use cannot be dismissed as additive agents in these cancers and as being significant risk factors

It is possible that the exposure to the HPV virus was other than of a sexual nature, because the virus can be present in oral secretions as well and could be transmitted that way, but the generally consensus is that this is an STD related cancer.





Sexually transmitted Herpes 2 is a common infection. It can be treated and suppressed with medication, but an effective vaccine would be a boon.
A recent vaccine study looked at vaccination in preventing HSV-1 “oral” herpes, and HSV 2 “sexual” herpes (although either can be oral or sexual, we tend to refer to them in the above ways.)
The vaccine prevented HSV 1….but not HSV 2. This is disappointing as HSV 2 is the primary concern and bother to most people.
So….for now, prevention of Herpes requires barrier methods (condoms), avoidance of sexual activity during ‘active’ phases of disease (when lesions are present), and suppression therapy with medications (although the full benefits of this in prevention remain unclear.
