I had carcinoma in situ about 6 years ago and had 2 separate surgeries to have it removed. I am 38 years old. It's been nearly two years since I went for my annual= and just went 3 weeks ago. Now, I had another abnormal pap and the doc wants to do a colposcopy and ecc in 2 weeks. I was tested for HPV each time and it always came back negative. How is it that these abnormal cells keep coming back without having the virus? How far could it have gone this time since it's been two years??
