Claim Text:
1. A device for testing presence, characterization, and tracking of benign or malignant masses, the device comprising: a. a signal generator configured to use multiple stimulus of simultaneously occurring frequencies with one or a plurality of receiving electrodes attached to one or more first locations on or in the patient, b. a sourcing electrode placed at one or more second locations on or in the patient; c. a computer program stored on a non-transient medium executed by a control system, d. a control system configured to use simultaneously occurring multi-frequencies coherent signals applied in a sequence to each sourcing electrode to stimulate tissue through; e. a control system configured to use ratio-metric measurements and coherent sampling across simultaneously occurring signals in the returning current from the tissue; f. a control system configured to use ratio measurements where the measurement examines the interaction between multiple-frequencies amplitudes and phases not the absolute values; g. a control system configured to use derived ratios created in clinical studies of tissue to determine the classification result selected from the group consisting of healthy, benign, and malignant tissue, and h. a control system configured to use an indicator that indicates the results to the user.
