About Uterine Fibroids

What are uterine fibroids?

Uterine Fibroids are non-cancerous growths located within the pelvis. They are the most common gynecological tumor and contribute to the widespread discomfort of millions of women. Depending upon the size, position, and number of growths a woman's risks and symptoms are generally increased. Fibroids can grow as a single or multiple tumors. They can be as small as an apple seed or as large as a grapefruit. In unusual cases they can become even larger.

Why should women know about fibroids?

It is critical that women understand Uterine Fibroid because as many as 60-80 percent of women may develop fibroids by the time they reach age 50. Most women with fibroids have no or minimal symptoms. However, in a substantial group of women, symptoms can be significant or severe, generally resulting in bleeding and/or pain. Fibroids also can put pressure on the bladder, causing frequent urination, or the rectum, causing rectal pressure, back pain or pain during sexual intercourse. Large multiple, fibroids can cause the abdomen to enlarge, making a woman look pregnant.
