A multi-modality breast cancer test assembly (20) of the type for detecting the position of potential breast cancer by performing thermography and optical spectroscopy and ultrasound tests (64). A contour recorder (108) takes and stores a contour-shape of the breast and a first contour analysis program (110) analyzes the contour-shape to generate and store a 3D model (112) of the breast having at least one testing coordinate (114) relative to a mass of the breast. At least one diagnostic program (122, 124, 126) initiates the diagnostic tests (60, 62, 64) at the at least one testing coordinate (114) and a data analysis program (128) analyzes the spatial interrelationship of the tests (60, 62, 64) at the testing coordinate (114) to detect the spatial position of a potential breast cancer within the breast.
