Abstract
Methods, kits, and apparatus for locating, labelling, and accessing breast ducts are described. An orifice to one or more ductal networks is marked to enhance visibility. In a first embodiment, the orifice is labelled using a specific binding substance, typically an antibody, specific for a tissue marker present on the orifice. Exemplary tissue markers include those present on the ductal epithelium, such as cytokeratins, including cytokeratin 8 and cytokeratin 18; cadhedrins, such as E cadhedrin; and epithelial membrane antigens. In a second embodiment, a dye is injected into the base of the nipple and preferentially accumulates at at least some of the orifices. Other marking techniques are also described. Marking of the ductal orifices permits reliable identification and access to each of the multiple ductal networks which may be present in an individual breast.
