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 seeds to large masses. Many women experience no symptoms, but some may have heavy menstrual bleeding, pelvic pain, or pressure. These fibroids are common, especially in women of reproductive age. The exact cause is not fully understood, but factors like hormones, genetics, and environment may play a role. Treatment options include medication, lifestyle changes, and surgical procedures, depending on the severity of symptoms and the size of the fibroids.
