What are Fibroids?

The Cause of Uterine Fibroids

The definite cause of fibroids is unknown. Many women have fibroids between the ages of 35 and 54, but not all women have symptoms or even notice the fibroids. There are certain risk factors that increase your chance of developing uterine fibroids.

Who Is at Risk of Developing Fibroids?

According to a number of recent studies, African American women are nearly three times more likely to develop uterine fibroids and suffer from more severe symptoms like heavy menstrual bleeding, anemia, and pelvic pain. As a result, hysterectomy rates among African American women are more than double in comparison to any other ethnic group. The majority of these hysterectomies are performed to treat non-cancerous conditions like uterine fibroids. 

If your gynecologist diagnoses a uterine fibroid, typically during a pelvic exam or after discussing your symptoms, talk with them or a uterine fibroid specialist about your treatment options including uterine fibroid embolization (UFE).

Who Is at Risk?

Uterine fibroids are the most common tumors within the female reproductive system, so all women are at a potential risk of developing them.

  • The majority of uterine fibroids are diagnosed and treated in women between the ages of 35 and 54. However, fibroids can and do occur in women under the age of 35, even as young as the early 20′s.
  • Studies demonstrate the prevalence of fibroids in 20-40% of women older than 35 years of age(1).
  • Multiple lines of evidence suggest that uterine fibroids have a disproportional effect on African-American women. African-American women have a higher cumulative risk of uterine fibroids(2), a threefold greater incidence and relative risk of fibroids(3)(4), and an earlier age of onset(5).
  • Most clinicians believe that shrinking of fibroids will occur when a woman goes through menopause.

During your annual gynecological examination your doctor will perform a vaginal exam and check the size of your uterus. If it feels enlarged, your doctor may prescribe an ultrasound, which can confirm the presence, location and size of fibroid tumors. Other methods can be used to confirm uterine fibroids including magnetic resonance imaging (MRI). After identifying the size and location of your fibroid(s), and also after other diagnostic tests, your doctor may recommend ruling out other, potentially more serious conditions and advise you of your options and a recommended course of uterine fibroid treatment.
