Oral Sex leads to cancer?

I was browsing through WebMd when I came across this article, which indicates that it's possible to transmit HPV through oral sex, which can then lead to mouth and throat cancer.

I remember when the Gardasil vaccine was first announced, Cindy was irked by the fact that she was outside the 9-26 age range - she just turned 30. (Turns out, there's research under way to increase the age range to 27-45.)

In the little bit of research I've run in the last few minutes, there's a whole range of HPV varieties, which can eventually lead to everything from penile to anal cancer - who knew?
