Please fire your doctor and get a new one, immediately. To say you may very well have cervical cancer before even doing a colposcopy was unconscionable on her part, especially with those PAP smear results, She knows the word cancer could frighten you so much, you would be easy to manipulate into a treatment that might not be appropriate for you. I am sorry she did that. My first ex-doctor did that to me, too, and she succeeded in causing me to panic into a hasty decision to agree to a surgery she preferred. In my own case she just wanted to make quick money rather than do what was best for me..
I will give you some links to help you understand all of this better, but before I do, be sure to
1. Look at your lab report, after the colposcopy/biopsy/ECC.
2. Get a thorough explanation of what you have, where it's located, how extensive it is, how many cervical quadrants are involved, if it's in the endocervical canal, and if it's in the endocervical glands. That will determine the best treatment option for you if you decide you need it.
3. If you decide to have surgery, get a full discussion of all of your treatment options - cryosurgery, leser, LEEP, and cold knife cone biopsy - before anything is recommended to you. This is a requirement that doctors are supposed to meet.
4. Insist on an HPV DNA test. Your insurance may not cover it, so the doctor may not have it, or your doctor can't offer it to you unless you ask for it, or you may have to go to a teaching hospital. You can also contact one of the better-known labs and find out which HPV DNA tests they do and then have the company send it to you. This may cost some money, but it's worth it in that it will give you more knowledge about what you are addressing.
I'll give you the links.
This shows the natural progression of HPV. I like it because it's so thorough.
