i have hpv, 5 years ago (21yo) i had LLETZ done, and CIN2 - 3 was removed. I have had regular paps and has shown clear after the op, but have recently had pap which showed CIN 1, some cells suggest CIN 2. So have had a biopsy, but results came back showing nothing. So doctor advised colposcopic evaluation in hospital, says need to go further in for another sample. How many times can it come back, & what should i expect? Scared & confused.
