Uterine fibroids are common in women of childbearing age and are formed by focal hyperplasia of the smooth muscle of the uterus, which gradually shrinks after menopause. The lesions cannot be removed with drug treatment. Sometimes fibroids can cause excessive menstruation, infertility, abdominal pain or pressure symptoms, and pregnant fibroids can rapidly increase in size and cause miscarriage, abdominal pain, and postpartum bleeding, so patients who have these symptoms or whose fibroids are more than 4 to 5 cm in diameter need surgery. Women who have not had children or young women who have had children with fibroids over 4 cm and those who have fibroids over 5 cm after the age of 40 need surgery.
