Amy, sorry to hear about what's happened . I can understand why you are getting the op done. With your family history and your own personal history so far, you don't want to take chances and wait too long. I think you are doing the best thing. You must have been through alot emotionally with all this, especially with how fast everything has happened. And with your sister having a hysterectomy at 25, thats young. Did she get a chance to have a family before the op?

Best wishes, and don't feel bad, everyone's situation is different
