How old are you? If you are young, because of the high regression rate and because LEEP puts a woman at a 7.9% risk of cervical incompetence, the ACOG wants doctors to be conservative in managing CIN I and II. It is recommended for doctors to either watch-and-wait or use something less invasive, such as cryosurgery or laser. In other words, you have several options available to you, and your doctor is supposed to educate you. If he hasn't, get rid of him, immediately, and get another doctor.
In the meantime,
1. Look at copies of all your lab reports, so that you know what has been happpening all along.
2. Get a full discussion of not only what you have, but where it's located, how extensive it is, how many cervical quadrants are involved, if there is dysplasia in the endocervical canal or the endocervical glands.
3. If you do require surgery, get a thorough discussion of the risks and benefits of all your treatment options - cryosurgery ,laser, LEEP, and cold knife cone biopsy - before a recommendation.
4. If you need surgery and the doctor recommends something, find out how experienced the doctor is. In addition, find out how often the doctors does that surgery, per week, how often the doctor does the other surgeries, and if the doctor has ever sent the patient to another doctor who is more experienced at surgery she qualifies for. That will help you determine if the doctor wants what is best for you and not what is best for the insurance company, as well as his or her bank account.
There also a lot you can do to boost your immune system. Several women have used alternative medicine, and there is a cervical_dysplasia group on Yahoo where women educate each other about their alternatives, in addition to traditional surgery.
The important factor is that you are fully educated so that your decision is informed.
