Electrical Impedance Scanning of the Breast


Electrical impedance scanning of the breast involves the transmission of continuous electricity into the body using either an electrical patch attached to the arm or a handheld cylinder. The electrical current travels through the breast where it is then measured at skin level by a probe placed on the breast. It is proposed that cancerous tissue conducts electricity differently than normal tissue; therefore, cancerous images may show up on the resulting imaging as a bright white spot.

An example of an electrical impedance scanning device is the T-Scan™ 2000.  This device received approval for marketing from the U. S. Food and Drug Administration (FDA) in 1999 with the following labeled indication:  “The T-Scan™ 2000 is intended for use as an adjunct to mammography in individuals who have equivocal mammographic findings with ACR Bi-RADS™ categories 3 or 4. In particular, it is not intended for use in cases with clear mammographic or non-mammographic indications for biopsy.




There is a lack of evidence in the published literature to show that electrical impedance scanning for the detection and classification of breast lesions can predict clinical events, be used to alter treatment or is effective as or more effective than currently used methods.
