galactography
(GA-lak-TAH-gruh-fee)
A procedure that uses x-rays to create pictures of milk ducts in the breast. A very thin catheter (tube) is inserted into the nipple, and a small amount of dye is injected into the duct. This makes the duct easier to see on the x-ray. Galactography is used in patients who have a bloody or clear discharge from one nipple. A small amount of the fluid may be collected to check for infection or cancer cells. Galactography may be used to help diagnose certain breast conditions, such as papillomas (wart-like growths) in a milk duct, fibrocystic breast changes, and breast cancer. Also called ductography.
