Well, the main thing we can hope for that awareness for oral cancer is raised. I also think that it is important to make it clear, that you do not have to be a 60 year old male chain smoking alcoholic to get this. Also the benefit of checkups and early detection was made.
RE HPV: Just last week I talked to the Director of the National Institute for Biological Standards and Control (UK) re oral cancer and HPV and HE though HPV was only involved in a minor portion of oral cancer occurrences... David I was thinking of you then, if your ears were ringing.
(for what is is worth I emailed him some info)
