I think you need to fire your doctor, immediately. Call the new doctor you want and tell the person who schedules appointments that your situation is urgent. If that doctor can't take you, get a referrel to another one who can. I don't like the way your current doctor is handling your case. It is within her right to make a recommendation. But not discussing the benefits and risks of all four methods of partial amputation before making that recommendation is unethical. LEEP is not the worst method, but neither is it the best method. It's just another method with benefits and risks, which all methods have. You also need a doctor who will show you the lab report and discuss anything you have questions about in great length.
The success rate of all four methods is exactly the same. The method most appropriate for you depends upon the kind of dysplasia you have and how extensive it is. The one big benefit of LEEP is that it produces a live specimen for pathology. (Then again, so does cold knife.) The one big risk of LEEP is infection. I keep hearing doctors say it only has a slightly higher risk of infection. But to be blunt, most women I have spoken to who had LEEP had infections, even if it was only slight. Something else to take into consideration is that insurance companies love LEEP because it's so cheap and can be done in the doctor's office. When I received the itemized bill, that electric knife was only $73.
Here are some links to explain the four methods. The first one is older, but the information is still good.

These links discuss LEEP itself. I'm not saying you shouldn't choose LEEP. I am saying, again, make sure you are informed about all of your choices, as well as the kind of dysplasia you have, before you make your decision. Your doctor also needs to respect your choice. But it needs to be an informed decision, and I am suspicious of a doctor who doesn't have a detailed discussion with you.
