How common is it for someone to need a myomectomy?

Very Common. Many women have fibroids. Some women don't have problems from fibroids, but other women have painful periods, heavy bleeding, pelvic pressure, pain with sex, or infertility. The only way to remove fibroids is surgery and so myomectomy is very common. Myomectomy can be done in different ways so not every surgery is the same.
Uncommon. Fibroids are very common, but most do not have an impact on fertility. Fibroids that are few in number, small in size, on the outside of the uterus, and not growing rapidly, carry little risk and often can simply be observed. Those that push into the uterine lining, the endometrium, distorting the lining, have an increased risk of bleeding and miscarriage and are more likely to need treatment.
