Leiomyomas, commonly known as uterine fibroids, are noncancerous tumors that develop in the smooth muscle tissue of the uterus. They can vary in size, from tiny seedlings to large masses, and may grow individually or in clusters. While many women with leiomyomas experience no symptoms, some may have heavy menstrual bleeding, pelvic pain, or pressure on nearby organs. These tumors are most prevalent in women of reproductive age and are influenced by hormones, particularly estrogen. Diagnosis typically involves imaging techniques such as ultrasound or MRI. Treatment options range from monitoring to medication or surgical procedures, depending on the severity of symptoms.
