What causes uterine fibroids.? Why do African-American women have an increased risk?

Why some women get uterine fibroids and others don't is still a mystery, but there may be a genetic connection. Estrogen production may increase the risk, because after menopause, fibroids shrink in size. Hormone replacement therapy (HRT) after menopause may increase the risk. Types of fibroids are discussed and the symptoms they cause.
