Fibroids (myomas) are benign (noncancerous) growths composed of fiber and muscle tissue that arise in the wall of the uterus. Fibroids are common, found in about 25% of all middle aged women. Usually, fibroids cause no problems and, hence, require no treatment. In some cases, fibroids create problems by virtue of either their size or their location. These problems include heavy periods, pelvic pain and interference with the function of neighboring organs.

Some fibroids require surgical excision utilizing open, laparoscopic or hysteroscopic techniques. Other fibroids may be treated by catheter-guided occlusion of the blood supply to the uterus. In special cases, the heavy bleeding caused by certain fibroids is avoided by using hormones to suppress/prevent menstruation.
