Ductoscopy or mammary ductoscopy (also: breast duct endoscopy, galactoscopy) is a medical diagnostic procedure for viewing and collecting epithelial cells and other internal features of the milk ducts.
It is capable of detecting smaller abnormalities than mammograms, MRI or ultrasound tests.
An imaging system displays the output of the scope on a computer monitor.
Latest Mammary Ductoscope, also called Micro Endoscope, is available with the diameter of 0.35 mm.
Ductoscopy can also be performed in conjunction with a lumpectomy, allowing the surgeon to achieve clean margins with a minimum of excess tissue removed.
