Uterine Fibroids

Fibroids Overview

A uterine fibroid is the most common benign (not cancerous) tumor of a woman's uterus (womb). Fibroids develop with the uterine wall or attach to it. They may grow as a single tumor or in clusters. Uterine fibroids can cause excessive menstrual bleeding, pelvic pain, and frequent urination.

  • These growths occur in about 25% of all women and are the leading cause of hysterectomy (removal of the uterus) in the United States. Of every woman older than 35 years, 1 in 5 has a uterine fibroid. An estimated 600,000 hysterectomies (removal of the uterus) are performed in the US annually, and at least one-third are for fibroids. Medications and newer, less invasive surgery can control the growth of fibroids.
  • Fibroids start in the muscle tissues of the uterus. They can grow into the uterine cavity, into the thickness of the uterine wall, or on the surface of the uterus into the abdominal cavity. Although these tumors are called fibroids, this term is misleading because they consist of muscle tissue, not fibrous tissue.

Unexpected bleeding is always a concern for a woman at any stage of life. Bleeding other than a normal menstrual period and even an abnormally heavy period can be great cause for alarm. The medical term for excessive or prolonged vaginal bleeding that occurs at the regular time of the menstrual cycle is known as menorrhagia. Metrorrhagia is the term used to refer to uterine bleeding at irregular intervals, particularly between the expected menstrual periods. Menometrorrhagia is the combination of the two, that is, excessive uterine bleeding, both at the usual time of menstrual periods and at other irregular intervals.

It is important to understand exactly what is causing the bleeding, its origin (uterus, vagina, or some other organ or tissue), and to make decisions about how to control or stop the bleeding.

  • A woman's normal menstrual cycle involves a complex series of hormonal events. An egg is released from the ova...
