Most uterine fibroids are harmless, do not cause symptoms, and shrink with menopause. However, some fibroids are painful, press on other internal organs, bleed and cause anemia, or cause pregnancy problems.
Uterine fibroids are lumps that grow on your uterus. You can have fibroids on the inside, on the outside, or in the wall of your uterus. Your doctor may call them fibroid tumors, leiomyomas, or myomas.
Uterine fibroid symptoms can develop slowly over several years or rapidly over several months. Most women with uterine fibroids have mild symptoms or none at all and never need treatment. For some women, uterine fibroid symptoms become a problem.
