I'm sorry you have been addressing this for so long. Your parents were right. It was necessary for you to get a different doctor. From what I have read, though, doctor was right, in that you are young. So per the ACOG, dysplasia has a high chance of regressing in very young women, especially with mild and moderate dysplasia.
The ACOG's concern was that after studies on cervical incompetence from LEEP, particularly because it's so popular, there is a 7.9% risk of miscarrying. The recommendation was to either watch the patient closely or to recommend something less invasive, such as cryosurgery (or laser). I personally don't have a lot of faith in doctors, anymore. But the ACOG is one regulatory group that seems to want what is best for the patient. It may be that there have been too many lawsuits from women who did not need treatment or had the wrong treatment. Or it may be that there is an alarming number of cerclages being done to prevent preterm delivery. I haven't spoken to the people who did the studies, so I don't know what led to this. But I am giving you the above information so that you can understand some of your ex-doctor's concerns.
However, the doctor should have given you a thorough explanation of what you have had, all along, so that you were educated. She should have also given you a thorough discussion of all of your options so that you could make an informed decision about what you wanted to do. Every case of dysplasia is different; every woman's body is different. That's why there are so many ways to approach it, and that's why whatever a doctor does, it must be customized for that woman.
I'm going to give you some links that will help you understand how to read your lab reports. The links will also explain the different treatment options and different types of dysplasia, so just click on the different tabs to maneuver around the websites. It is important to make sure you are fully educated before you agree to anything - waiting longer to see if it finally regresses or choosing traditional surgery. If you do choose surgery, make sure you do what is best for your condition and not what the doctor likes, especially since there are several tools. Doctors have a bad habit of pushing the "treatment de jour" on patients. Please make sure whatever you choose to do, it is appropriate. I realize how upset and frightened you are. But from personal experience, it is very empowering to be fully educated. It will take away the mystery, which reduces the fear because you will be actively involved in what is best. Please also remember that your doctor must work with you. He or she cannot do things to you.
This is an older link, but it's easy to understand.

This link is to a website of one of the few doctors I have run across who wants his patients to be educated. I wish all doctors would follow his example.

Something you will want to when you look at the lab reports, again, is to check to see if there is any dysplasia in the endocervical canal or the endicervical glands. You also need to know how many cervical quadrants are involved and how extensive it is. Where were the biopsies taken? What did each one show? Do the reports show any signs of bacterial or yeast infections?
Please also insist on getting tested for HPV strain you have. Roche has AMPLICOR, which is a new test that will tell you exactly what you have. Insurance companies don't like to pay for it, and the FDA has a cozy relationship with certain pharmaceutical corporations. So, you may have to pay for it yourself. Or your doctor may not have it. Or the doctor may not be able to offer it you unless you ask for it. Or you may have to go to a teaching hospital. But I was tested to see which HPV strain I had, and it made all the difference in the world because I knew how to set up a strategy to protect my health. If you have a more aggressive strain, such as HPV 18, then that will tell you if you should insist on surgery. I had HPV-CP6108. I clearly had the time to set up alternative medicine as Plan A.
If it helps you, please know all of here are putting out good thoughts for you. And please bring somebody with you to help you when you talk to the doctor, in case you feel overwhelmed by what is being said or in case you are afraid you won't remember an answer to a question.
