Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. Size of the mioma is not the only factor which should be considered. It depends on symptoms such as bleeding or pain , if surgery will be performed or not. Also it is recommended if heavy uterine bleeding and/or anemia has continued after several months of therapy with birth control hormones and a nonsteroidal anti-inflammatory drug. Since you are in menopause, it may be reasonable to have hormonal therapy first and then if this is unsuccesful, surgery can be performed. The treatment then include myomectomy or hysterectomy can be done through one or more small incisions using laparoscopy, through the vagina, or through a larger abdominal cut. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
