The Full form of DNC is Dilation and Curettage. DNC is a procedure to remove tissue from inside the uterus. Doctors 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. Dilation means opening up the cervix (the opening to the uterus) and then Curettage (scraping out the uterine lining). Dilation and curettage can diagnose or treat a uterine condition. To diagnose a condition, doctor might recommend a type of DNC called endometrial sampling to diagnose a condition if a patient has abnormal uterine bleeding or he is experiencing bleeding after menopause. Doctor discovers abnormal endometrial cells during a routine test for cervical cancer. To perform the test, the doctor collects a tissue sample from the lining of your uterus (endometrium) and sends the sample to a lab for testing. The test can check for Endometrial hyperplasia — a precancerous condition in which the uterine lining becomes too thick, uterine polyps and uterine cancer. A patient should contact his doctor if he is experiencing any of the following after a D&C: bleeding that’s heavy enough that he needs to change pads every hour, cramps lasting more than 48 hours, pain that gets worse instead of better or fever.
