The definitive method to determine whether a condition is benign or cancerous involves obtaining tissue samples. This procedure enables the collection of breast tissue samples to confirm or rule out the presence of breast disease. A local anesthetic will first be administered to numb the area. During the procedure, a very thin needle is inserted into the breast with a syringe to remove fluid from a cyst within the breast. The fluid is then sent to a lab for analysis.

There is no preparation for this exam.
