Bret,
Congratulations on your good check-up. I don't know about an Epstein-Barr link, I know there are other viruses that have strong possibity of being linked to scc.
Of course, as long as they can't cure or prevent those viruses, there isn't much good in knowing about the connection. I mean on a personal level - it does not do me any good to know whether a virus caused my cancer until there is a cure for that virus. But in general, the more that is known, the more likely it is that some sort of cure or prevention or alleviation is found.
I never smoked at all or drank to excess either, yet I have had two completely separate cancers this year, so naturally I am wondering and wondering and wondering what in the world did I do or not do... But at today's level of knowledge there is no answer. I am just glad I live today and not a hundred years ago.
Good luck,
Leena
