Thanks for your question. There are several issues to think about for you. A CIN I lesion can progress to more severe dysplasia or even cancer if left untreated. You don t mention your age but women under 30 are sometimes able to fight off a CIN I lesion so not all doctors immediately treat CIN I, even with a biopsy proven diagnosis. If it were me, I would want it treated regardless of my age. A LEEP procedure is short, simple and much less costly than a hysterectomy. Even with hysterectomy, you are still at risk for abnormal pap smears and formation of these types of lesions. Some gynecologists prefer to have the uterus and cervix in place when pap smears are abnormal. The thinking is, if dysplasia recurs, you can treat a cervix easier than you may when having to treat the vagina where the cervix used to be. Hysterectomy would treat the dysplasia as well as the heavier periods, but will not eradicate the human papillomavirus that causes the cell changes that can lead to cervical cancer. An option for you would be to have the LEEP procedure and undergo an endometrial ablation at the same time. This procedure uses different types of energy sources to eliminate the lining of the uterus that sheds with menstrual periods. All of these procedures take less than twenty minutes and can all be performed in an office setting under local or IV sedation. You would need a permanent form of birth control (vasectomy, or an Essure implant could be placed at the same time as your ablation if using Hydrothermablation) since pregnancy is not recommended after endometrial ablation. I hope this answer helps and is not confusing. There is a lot for you to think about prior to making your decision. I am available for follow up should you need to ask further questions.
