I Had A Culposcopy Monday And The Dr. Just Called

I had a culposcopy Monday and the dr. just called with my results. She found CIN1 tissue in my canal (or OS), but no lesions were found on my cervix. The dr. is suggesting for me to go to the OR to get my cervix dialated so that a better culture can be taken and to insure the CIN1 dysplasia is the extent of it. I am hesitant because this is a new dr. and she seems very aggressive. Is there any suggestions you can make?
