I had a colposcopy, which didn't involve any "procedure" - I sat with my legs in stirrups while the dr did the usual with the speculum, and then looked at my cervix through a microscope. He painted something on to test for pre-cancerous cells, which showed as negative. He then painted something else on to test for a particular virus that can show as an abnormal smear (I now believe he was looking for HPV) and that showed as positive, so absolutely fine, no removal of cells, or pain.
My sister had the "hot wire" done, she didn't like it but was lucky that in those days they tested under-25s, as she was 20 and had pre-cancerous cells - she may have become one of those "doesn't happen in young people" statistics, had it not been for the colposcopy!
