Uterine fibroids are common, noncancerous (benign) growths that develop in or on the uterus, also known as leiomyomas or myomas. They vary in size and can cause symptoms such as heavy menstrual bleeding, pelvic pain and pressure, frequent urination, and lower back pain. While many fibroids are asymptomatic, they can impact fertility and are often diagnosed via physical exam and ultrasound. Treatments range from medication to procedures and surgery, with the need for treatment dependent on symptom severity.
