Frank,

I have never seen anyone's path report on HPV come back identifying more than one strain of HPV so I don't know if that's probable but I have seen other than 16 being identified with SCC but as Brian said 16 is so far the No 1 villain in OC.

Yes 95% must have been misheard. The most recent statistics I have heard is that up to 70% of new oropharyngeal cancers are caused by HPV most commonly associated with the tonsils or base of tongue, white males, non smoking, casual drinking, college educated and born after 1948. Usually mets to the nodes are also common before they are diagnosed.

I too hope researchers find out why 80% of the population by age 50 have been exposed to the HPV virus yet so few as expressed as a % develop cancer. I was told my immune system must have blinked and let the leash on the dog go and Johns Hopkins is doing a trial on the effectiveness of boosting the immune system's response to post HPV exposure so lets hope they can reach a positive conclusion. But all types of cancer seems to be a mystery otherwise everyone that smoked would get cancer, etc.
