Fibroids are a growth within the uterine wall. Many women have them, some are big, some are small, some grow very quickly and some very slowly. The cause of fibroids is a hormonal imbalance, specifically, too much estrogen in relation to progesterone. The excess estrogen needs a place to go so the body deposits it safely in the wall of the uterus.
Fibroids are almost always benign, the problems arise when the fibroids become large and induce heavy periods, hemorrhaging and cramping. When this occurs the conventional medical system recommends surgery. The surgery recommended most often for large fibroids is a hysterectomy where the uterus containing the fibroids is removed.
