In 2010, the U.S. Population is ~308 Million.
About 51% of the U.S. Population is women, so about 157 Million are women and girls.
About 138 Million of the U.S. Population are women over 19.
Studies have shown that about 79% of women have uterine fibroids, so in 2010, 109 Million women have uterine fibroids.
Only about 30% of women will require some form of treatment for uterine fibroids, which is around 33 Million women over 19 currently in the U.S.
Unless you start to have symptoms, you probably won’t know that you have uterine fibroids. Sometimes, health care providers find fibroids during a routine gynecological exam.
Hysterectomy (removal of the uterus) is not the best option for every woman with uterine fibroids. If you want to have children, then you would want to avoid this treatment. Likewise, if you don't have symptoms of uterine fibroids, or your fibroids are small, you may have better results from pain medications or hormone treatments. Health care providers are also exploring less-invasive surgical treatments for fibroids that save the uterus.
Most women who have fibroids do not have problems with fertility and are able to get pregnant. In some cases, fibroids can prevent a woman from getting pregnant through natural methods. However, advances in treatments for fibroids and infertility have greatly improved the chances for a woman to get pregnant, even if she has uterine fibroids.
