I've had a series of abnormal pap smears over the past 18 months or so. Ascus 1st, then 6 months later lsil, followed by a negative ecc. My most recent pap smear was again lsil. Shortly after that I has a biopsy and ecc. The biopsy that followed was negative but the ecc results were lsil. Anyone have similar experience or any info on what it may mean for the biopsy to be negative but the ecc come back with low grade changes?
