• Uterine fibroids are benign tumors that originate in the uterus (womb).
• It is not known exactly why women develop uterine fibroids.
• Most women with uterine fibroids have no symptoms. However, fibroids can cause a number of symptoms depending on their size, location within the uterus, and how close they are to adjacent pelvic organs.
• Uterine fibroids are diagnosed by pelvic exam and even more commonly by ultrasound.
• If treatment for uterine fibroids is required, both surgical and medical treatment options are available.

Uterine fibroids are benign tumors that originate in the uterus (womb). Although they are composed of the same smooth muscle fibers as the uterine wall (myometrium), they are many times denser than normal myometrium. Uterine fibroids are usually round or semi-round in shape.

Uterine fibroids are often described based upon their location within the uterus. Subserosal fibroids are located beneath the serosa (the lining membrane on the outside of the organ). These often appear localized on the outside surface of the uterus or may be attached to the outside surface by a pedicle. Submucosal (submucous) fibroids are located inside the uterine cavity beneath the lining of the uterus. Intramural fibroids are located within the muscular wall of the uterus.
