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.
