A risk factor is something that increases your likelihood of getting a disease or condition.

It is possible to develop uterine fibroids with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing fibroids. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.

Fibroids may be more common in women in their 30s and 40s.

Black women tend to have more and larger fibroids at an earlier age. Asian women may have a lower risk.

Women who are overweight or obese are also at a slightly higher risk for fibroids.

There may also be a genetic link in the development of fibroids.

Women who have given birth appear to be at lower risk for uterine fibroids.
