I have suffered from abnormal smears for the last 6 years or so. I have also had 3 or 4 LETZ Biopsies. Every time the Biopsy is done, the result comes back as clear. Yesterday I had another biopsy taken. The consultant again said " I can't see anything abnormal about your cervix but we will do the biopsy. My only conern would be if it comes back as clear again. What would be causing your smears to show moderate to high grade changes". I have the HPV Virus but I don;t know which strain. I am praying it comes back clear but at the same time I am worried about what is causing my cell changes to show up on smear tests, negating the need for my colcoscopy visits and Biopsies. Has anyone else suiffered from recurrent cells changes and ongoing biopsies which turn out to be clear? This has started to really worry me and I am wondering is there something else that they are missing.
