Re: Leep results
Yes, CIN3 is "carcinoma in situ", although that's a term that's fallen into disfavor lately. Yes, it is also "stage zero", another term not widely used today.
It doesn't mean you have cancer, it's just the highest level of precancer.
I don't understand the terminology in your report, either, and I don't see where it says you didn't get clear margins. I mean, I don't interpret it to mean that.
Did your doctor tell you that you didn't get clear margins?
I'd call back and ask.
Best of luck!
