Breast tissue sampling is taking cells from breast tissue to check under a microscope. Abnormal cells in breast fluid have been linked to an increased risk of breast cancer in some studies. Scientists are studying whether breast tissue sampling can be used to find breast cancer at an early stage or predict the risk of developing breast cancer. Three ways of taking tissue samples are being studied:
Fine-needle aspiration: A thin needle is inserted into the breast tissue around the areola (darkened area around the nipple) to take out a sample of cells and fluid.
Nipple aspiration: The use of gentle suction to collect fluid through the nipple. This is done with a device similar to the breast pumps used by women who are breast-feeding.
Ductal lavage: A hair-size catheter (tube) is inserted into the nipple and a small amount of salt water is released into the duct. The water picks up breast cells and is removed.
Screening clinical trials are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Web site.
