Millions of U.S. women are debilitated each year by fibroids, which are noncancerous growths of the uterus that can cause heavy periods, severe pain, and difficulty conceiving. According to the U.S. National Institutes of Health, over 26 million in the U.S. have fibroids. Fibroids are often treated with invasive surgery to remove the fibroids or with hysterectomies.

Research has shown that mifepristone can significantly reduce fibroids. Yet, it is not available for that use in the United States.
