Fibroids are common, non-cancerous growths that can appear in the uterus and most often do so in a woman's childbearing years. Fibroids come in all sizes and can grow quickly or remain small, and though there are not always symptoms, sometimes heavy bleeding or a very long menstrual cycle are a sign fibroids are present. Though there is not a known cause other than being a woman of childbearing age, fibroids are known to be hereditary (run in families).
