I'm sorry I came into this late, so I don't know what you chose to do. I'll ask you some questions and then post some links for you.
1. Did you see the lab report?
2. Did your doctor explain not only the grade of dysplasia you had, but where it was located, how extensive it was, how many cervical qudrants were involved, if it was in the endocervical canal, and if it was in the endocervical glands? That would have determined your treatment options, right there.
3. Did your doctor give you a thorough discussion of the risks and benefits of all your surgical options - cryosurgery, laser, LEEP, and cold knife cone biopsy - before recommendation? This is a requirement.
If you answer "no" to even one question, please get a different doctor, immediately, for your follow-up care. Your body is too valuable, and you deserve only a doctor who cares enough and is ethical enough to want you to be educated enough to make an informed decision.
Because you weren't sure if you should wait or go ahead with surgery, I'll give you a link about HPV and the progression and regression rates, so that you'll have the information for later.

Per the ASCCP, CIN II has a 40% chance of clearing itself up, a 40% chance of no change, and a 20% chance of progressing to CIN III. I tried maneuvering through their website, but some of the links seems to have been removed. Perhaps they're doing and overhaul of the site.
This is one interesting study by Oregon State about surgical options. I always save copies in case they "mysteriously" disappear.

Here is their main site for women's health issues.

Here is what the ACOG has to say, as how to manage CIN II has become more and more controversial. There are also several links within the text for further reading. (I saved copies of this, too, since LEEP has become a very sensitive issue for patients and doctors alike.)

If you already had the surgery, I definitely hope things went well for you. If you decided to wait, I hope you have been able to educate yourself. There are also links for boosting your immune system to clear it up. If you want those, I can post them. I just don't want to overload you with too much reading material, right now.
