Dilation and curettage (D&C) is a procedure to remove tissue from inside your uterus. Health care providers perform dilation and curettage to diagnose and treat certain uterine conditions such as heavy bleeding or to clear the uterine lining after a miscarriage or abortion. In a dilation and curettage, your provider uses small instruments or a medication to open (dilate) the lower, narrow part of your uterus (cervix). Your provider then uses a surgical instrument called a curette, which can be a sharp instrument or suction device, to remove uterine tissue.
