I had an abnormal pap smear. The doctor said that it was cervical displaysia and that I needed to come in for another exam. I would like to know more about the next procedure with the camera that they are using. I would also like to know how this condition came about, what can be done, and a basic history of it. I would also like to know about how the biopsy works. I am nervous. Is this normal for healthy 20 year old?
