How Common Are Uterine Fibroids?

Uterine fibroids are noncancerous growths in the uterus. They are the most common type of solid tumor that can grow in the pelvis. Fibroids affect 20 to 50 out of 100 reproductive-aged women.1

Most women with fibroids do not have symptoms. For those who do, symptoms can range from mild to severe. Symptoms depend on how large a fibroid is, where it is, and whether it is bleeding or pressing on an internal organ.

Fibroids are often first found during a routine pelvic exam. To double check, an ultrasound may be performed, either transvaginally or abdominally. A three-dimensional (3D) ultrasound or an MRI (magnetic resonance imaging) can also be used to find the fibroids, a process called fibroid mapping.

  • As women age, especially from their 30s and 40s until menopause, usually at about age 50.
