Out of curiosity, did you see the lab reports from the biopsy taken during the colposcopy and from the LEEP? Did she tell you if the endocervical glands were involved? From what you posted, your doctor's nonchalence about your concerns is grounds for firing her, right there. Please get a different doctor, or at least a second opinion. It is your right to have your body given more regard than that, and I am so sorry the current doctor is adding to your stress. Something I always tell people is
1. Look at all of the lab reports. They're much easier to understand than people realize, and the internet is full of information about what the terms mean.
2. Have a detailed discussion about what you have, how extensive it is, and if anything else is involved.
3. Have a detailed discussion about all of your options, which are cryosurgery, laser, LEEP, cold knife, and at the more extreme, trachelectomy (removes the cervix and leaves the uterus for fertility purposes), and hysterectomy.
It definitely helps remove a big part of the fear in that it removes the mystery. It also gets you actively involved in making informed decisions that protect your health and your life.
It also helps to bring somebody else if you are uncomfortable or feel you might forget any questions to ask. (Writing down what you want to know will help, too.) Again, I am sorry your doctor hasn't been as understanding of your concerns.
