Factors that increase a woman's risk of developing uterine fibroids include:¹

• Age. Fibroids become more common as women age, especially from the 30s and 40s through menopause. About 80% of women develop uterine fibroids by the time they reach age 50.⁴ After menopause, fibroids usually shrink.
• Family history. Having a family member with fibroids increases your risk.
• Ethnic origin. Black women are more likely to develop fibroids than white women.
• Obesity.⁶
