Loop treatment


I've just joined this forum, with a request for some advice.

I have had irrelgular bleeding and was seen by the Dr, who urgently refered me to the Hospital. This then moved on to me having a colposcopy & a Biopsy. The smear came back abnormal and my biopsy showed results meaning I needed to urgently have Loop treatement. This is all I've been told today and I'm not really sure what it's for. I'm having it on Thursday and was told, it needed to be done asap. Please could anyone help to understand what it means, cell wise.
