Uterine fibroids are noncancerous tumors that grow in or on the wall of the uterus and are commonly seen during a woman's reproductive years. Most small fibroids are asymptomatic and only require regular monitoring by your gynecologist. However, larger fibroids can cause significant symptoms that require medical care. If left untreated, they may lead to complications like heavy bleeding, severe pelvic pain, fertility issues, or anemia. If you are experiencing any of these symptoms, see a doctor at the earliest.
