One study found that between 80% and 90% of African American women and 70% of white women will develop fibroids by age 50.1
Some may have no symptoms. However, hundreds of thousands of women seek treatment for fibroids each year.
Research shows that over 90% of women who are newly diagnosed with fibroids will seek medical or surgical treatment for the condition within a year of the diagnosis.2,3 In 2000, more than 250,000 hospital admissions were related to uterine fibroids. Every year, fibroids lead to more than 200,000 hysterectomies.4 Women who wish to have children have the option of myomectomy, a surgical procedure that removes the fibroids while leaving the uterus intact.
Fibroids usually grow in women of childbearing age. Among U.S. women ages 25 to 44, about 30% have symptoms of fibroids.2 Affected African American women are more likely to have multiple fibroids.5 We don't know exactly how many new cases of fibroids occur in a year, as fibroids may not cause any symptoms, but clearly millions of American women have fibroids at any one time.
There have been reports of rare cases in which young girls, who have not yet started their periods (prepubertal), had small fibroids. For African American women, fibroids typically develop at a younger age, grow larger, and cause more severe symptoms.4
Fibroids may shrink after menopause. However, research shows that they are more likely to shrink in postmenopausal white women than in premenopausal black women.
Several factors affect a woman's risk for having uterine fibroids.2
