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.
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.
