My doctor just phoned. The biopsy is all clear, no sign of any CGIN or cancer, so they had removed it all and now I am as clear as anyone else.
A tiny part of me thinks I didn't need the surgery and feel sad but, we would never had known, they said they couldn't be sure they'd removed it all and the next time a smear picked it up it might be more advanced. So, it is best. I did need it.
