Fibroids are common, benign tumors of the uterus that affect about 30% of all women. They are the most frequently diagnosed tumor of the female pelvis. They are made of nodules of smooth muscle cells and fibrous tissue that usually develop in the wall of the uterus. Fibroids may grow as a single nodule or in clusters. They may range in size from 1/10 of an inch to 8 inches in diameter.

The majority of women with uterine fibroids have no symptoms; women who experience symptoms often report:

  • excessive or painful bleeding during menstruation
  • bleeding between periods
  • a feeling of fullness in the lower abdomen
  • frequent urination resulting from a fibroid that presses on the bladder
  • pain during sexual intercourse
  • low back pain


Researchers have not identified any factors that cause fibroids to grow, but research has shown that you are more likely to have uterine fibroids if you:

  • are old enough to have a period or a baby
  • are African American
  • have a sedentary lifestyle
  • are overweight

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