Fibroids are attached very securely to the uterine cavity by a stalk, or else they more commonly "bulge" into the cavity like boulders in a cave. Only a fibroid on a stalk pedunculated may be removed by a "D&C", but stalked fibroids are the exception, not the rule.

Those, particularly those just under the lining of the uterus, commonly cause menstrual bleeding to be heavier or to last longer than usual. Anemia may result from the loss of blood.

Fibroids now account for 38% of these operations, but the rates vary widely by ethnic group. In a major 2002 government report, 68% of fibroid-related hysterectomies were performed in African-American women, 33% in Caucasians, and 45% among women of other ethnic groups.

They may be felt during a pelvic exam, but many times myomas that are causing symptoms may be missed if the examiner relies just on the examination. Also, other conditions such as adenomyosis or ovarian cysts may be mistaken for fibroids.

They usually are not associated with cancer, they rarely develop into cancer (in less than 0.1 percent of cases). Having these does not increase your risk for uterine cancer. Many can appear as a single large tumor or as a cluster of small ones.

They are usually present as a central lower abdominal mass rather than totally involving the adnexa. Ultrasound or magnetic resonance imaging often can differentiate uterine leiomyomata from ovarian tumors, but not always.

Fibroids are benign (not cancerous) tumors of the muscular layers of the womb or uterus. They're extremely common and usually occur as several clusters of different sizes. They begin as small seedlings that spread throughout the muscular walls of the uterus. They can be so tiny that you need a microscope to see them.

They also can change the shape of the uterus as they grow. This can make it difficult to become pregnant or can cause problems during a pregnancy. Many have also been linked with a reduction in the success rate of fertility treatments. Fibroids can dramatically increase in size during pregnancy. This is thought to occur because of the increase in estrogen levels during pregnancy.

They will grow back after GNRH therapy is stopped, Fibroids are more common in women who are overweight and women of Afro-Caribbean origin . Many may also cause pain or a feeling of pressure or heaviness in the lower pelvic area (the area between the hip bones), the back or the legs. Some women have pain during sexual intercourse.

The one's that are attached to the uterus by a stem may twist. This can cause pain, nausea, or fever.
