Abstract

In accordance with the apparatus, the method of the present invention, a bio-potential lesion sensor (12) is placed directly over a lesion in a symptomatic breast, and a reference sensor (14) is located away from the symptomatic breast. A plurality of electro-potential test measurements are taken during a test period with the lesion sensor (12), and averaged to obtain a primary test potential. This primary test potential can be weighted to compensate for one or more biologic variables such as patient age, time in the patient menstrual cycle, and time of day during which the measurement is taken.
