Uterine fibroids (also known as uterine myomas or simply fibroids) are benign growths that develop in the muscle layer of the uterus. These growths can range from very small to large tumors. Uterine fibroids are common and occur in many women of reproductive age, though they do not always cause symptoms. When symptoms do occur, they may include menstrual irregularities, heavy menstrual bleeding, pelvic pain, or pressure on the bladder or bowel. The exact cause of uterine fibroids is not fully understood, but hormonal factors may play a role.

Treatment options vary from monitoring without intervention to medical therapy or surgical removal, depending on the size, number, symptoms, and the patient’s desire for pregnancy.
