Now that the HPV connection is concrete, I believe (from what most of the lecturers I have been touring with state) is that it is still about 5 % that we have no clue why they come to this disease. Gene's and other unkowns at this time will likely always keep that number there. It will never come down to we know in everyone how they came to it. As a side note I sent an email to Gillison et.al. about the use of the name throat cancer for OSCC when talking to lay people, and in naming their articles, and what harm I think this is doing is keeping OC in the dark recesses of people's awareness.
