I also had squamous cell cancer to the one area that never gets sun. Went through chemo and radiation. Seemed to clear it up. That was twelve years ago. Now I have endometrial cancer and believe it was caused by the former problem. I was never tested for HPV but believe that it had caused the squamous cell cancer to that particular area. As far as I know, HPV cannot be eradicated from your system. I guess it's similar to herpes in that respect.
