What Is a Leiomyomatous Uterus?

Leiomyomas are common among women in their 40s and 50s and are the main cause of hysterectomies for about 25 percent of women in this age group. Twenty-five percent of white women and 50 percent of black women develop leiomyomatous uteri. Although only a quarter of women with a leiomyomatous uterus require hysterectomies, 77 percent of all women who have hysterectomies show the tumors in the pathology results.
