Abstract:

A sample for diagnosis of breast cancer can be prepared by isolating a ductal fluid sample from one duct of a breast of a patient. The isolated ductal fluid is not mixed with ductal fluid from any other duct of the breast. Generally the target duct is not spontaneously discharging. The isolated ductal fluid sample can be examined to determine the presence or absence of a marker associated with cancer or pre-cancer. An isolated ductal fluid sample not mixed with ductal fluid from any other duct of the breast permits identification of the duct which is diseased and provides increased sensitivity for existing diagnostic and analytic techniques.
