Fibroids are quite common among women in their thirties and forties.
Typically, fibroids occur in groups, cause no symptoms, and are small in size, although they can sometimes grow larger. They are usually harmless unless they exert pressure on surrounding organs, in which case they can cause pain, abnormal bleeding, and an enlarged uterus. Fibroids sometimes cause infertility.
