hi Brian,
your perspective helps me appreciate the broader picture. yet,
did i understand what you wrote?
HPV 16/18 comes and goes - not a permanent thing? that would really complicate things... like thinking that it might be associated with life style some 30 yrs ago. perhaps the virus takes on a form that just isn't picked up by the screening technique reliably.
so, what's the buzz?
