I can't remember which particular study or paper I read that statistic from but that 70% has stuck with me. Remember I said 70% of the new SCC cases in the Oropharynx region (BOT, Tonsils, etc) not all new OC cases. I also remember one study profiling the "typical" HPV candidate as white male, college educated, non smoker, income > $50,000, BOT or tonsil primary with nodal involvement. That particular study was released over a year ago and as with everything under constant query, newer studies may change previous understandings. I'm pretty sure Brian has posted all creditable studies on HPV so read away.
