She had laparoscopic laser excision surgery and did an insane amount of research before finding that doctor. Pretty sure that’s still considered the best method.
If they recommend a hysterectomy, see if you can keep your ovaries. That way you still ovulate and create hormones so you don’t go through forced menopause.
Also, the doctor will likely tell you they may not know exactly what can/should be done until they’re actually in there and looking. At least that’s how it worked for us.
