Breast duct endoscopy is a diagnostic method used to detect the presence of abnormal tissue in the lining of the breast ducts.
In breast duct endoscopy, a thin, flexible, lighted tube is inserted via the nipple into the breast ducts within the breast. As the outside of the endoscope tube is connected to a camera, the appearance of tissue inside the breast ducts can be seen. Also, during the procedure, biopsy samples of fluid and tissue may be removed from the breast ducts for laboratory examination.
