hey again klo, and thanks for replying.
I do see your point. future developments may help me in some form or another. so finding out the possible cause may prove a smart move. to be honest, i hadn't heard of HPV before tonight.. so i was pretty unfamiliar with it. i've read a small amount now. and it obviously looks a possibility.

i guess this has all happened so quick and until last week, i was still in limbo between my treatment and scan. so looking forward though, i'll bring it up with my surgeon at my next appointment coming up.

thanks for taking the time to reply.
cheers,
dave
