This procedure (also called a "D&C") removes tissue from inside your uterus. Your uterus is the organ responsible for pregnancies and menstrual periods. We may do a D&C to get a sample of tissue to study. We call this a "biopsy". We may do it to treat a problem inside your uterus. Or, we may do it to clear away tissue that was left behind after a miscarriage or a delivery.
