Uterine fibroids are noncancerous growths that develop in the uterus. They are made of muscle and fibrous tissue and can vary in size, from tiny seedlings to large masses. Many women experience fibroids during their reproductive years, and they can be found in different locations within the uterus, such as the inner lining or the outer wall. While some women with uterine fibroids may not have any symptoms, others may experience heavy menstrual bleeding, pelvic pain, or pressure. Treatment options include medication, surgery, or monitoring, depending on the size of the fibroids and the severity of symptoms.
