Electrical impedance imaging scans the breast for electrical conductivity, based on the idea that breast cancer cells conduct electricity better. It involves passing a very small electrical current through the body and detecting it on the skin of the breast with a small probe (similar to an ultrasound probe). The test does not use radiation and does not require breast compression.
