<unk>  is a non-invasive screening procedure. It is used to detect precancerous and cancerous cells in the breast ducts. It is a safe and well-tolerated procedure. Some doctors might apply anesthetic cream to numb the nipple area. In<unk> , the doctor applies suction to the nipple in order to bring out fluid from the milk ducts that eventually end at the nipple. A micro-catheter is inserted into the milk duct and the fluid is washed into the duct to rinse out the cells. The fluid is then retrieved from the nipple and sent for laboratory evaluation. This procedure is also called a "Breast Pap-Smear" by some doctors.
