I had a pap smear in August that showed carcinoma in situ. My dr. had me return for a colposcopy with biopsies and told me that my cervix appeared abnormal during the exam. He suggested I would need a LEEP and we waited for my biopsy results. The biopsy came back normal, just a mild dysplasia. He could not explain the discrepancy and said I needed the LEEP anyway to be safe. I got a second opinion and had the LEEP in late August. The dr. told me he got all of the bad tissue and the margins were clear. When the pathology report came back it showed all normal tissue-none of the abnormalities my dr. said he saw. He has since sent me to a GYN Oncologist who I will see in a couple of weeks. They had my pap reread to ensure it was accurate and the second reading concurred that it was carcinoma in situ. I am completely confused- how can I have a severe lesion that appears only in the pap but not in the biopsies or LEEP? I will have another colposcopy in a couple of weeks. Can anyone help? I don't understand how a pap can be so severely abnormal and my biopsies and surgery yielded only normal tissue.
