A method for the detection and localization of breast microcalcification through a precise method of ultrasound impacting and ultrasound frequency wave detection which will enable the system to detect not only if there is a microcalcification in the breast, but the precise location of the microcalcification and the mass of the microcalcification. The invention is also a method and system that provides bi-modal guided stimulation of a targeted mass within the breast to determine the location and nature of the microcalcification within the breast.
