This information is currently being used by oncologists, breast cancer surgeons, and their patients to weigh management options such as ongoing surveillance and risk reduction drug therapy. Before ductal lavage begins, an anesthetic cream is applied to the nipple to numb the area. Next, a small suction cup akin to a manual breast pump, is used to help draw tiny amounts of ductal fluid up to the nipple surface. These fluid droplets help locate the natural opening of the ducts on the nipple. Once the duct is identified, a tiny microcatheter is inserted into the ductal opening.
Some anesthetic is delivered through the microcatheter to numb the inside of the duct.
The fluid is then put into a collection vial and sent to a laboratory. Ductal lavage does not replace standard breast cancer detection tools and should be used in conjunction with mammography, breast-self examination, and clinical examination.
