Abstract
Methods for scanning and diagnosing the presence or absence of malignant cancerous tissue in areas such as mammary tissue and lymph nodes of human and animal bodies by measuring the electromotive force generated by a platinum electrode or probe in contact with skin or subcutaneous portions of a body area to be diagnosed for presence or absence of said malignant tissue, and recording as suspect areas of malignant growth at least those body areas which were in contact with the probe or electrode when a significant negative electromotive force in the order of minus two millivolts or less was measured, the electromotive force being measured across two electrodes or probes, one in contact with normal skin or tissue, and the other in contact with skin or subcutaneous portions of the body area to be diagnosed.
