Abstract: A method for detecting cancerous status of a suspected lymph node (LN) to be cancerous. The method includes measuring fatty acid oxidation (FAO) in the suspected LN by measuring a charge transfer resistance (RCT) associated with the suspected LN, and detecting, utilizing one or more processors, a cancerous status of the suspected LN. Detecting the cancerous status of the suspected LN includes detecting the suspected LN is cancer involved if the measured RCT is less than a reference RCT value, or detecting the suspected LN is healthy if the measured RCT is more than the reference RCT value.

Abstract: A method for tumor suppression. The method includes inserting an active part of a wire into a cancerous tumor, electrostatically stimulating cancer cells of the cancerous tumor by injecting positive electrostatic charges to the cancer cells, and reducing size of the cancerous tumor responsive to the electrostatically stimulating cancer cells of the cancerous tumor. The active part of the wire is located at a first end of the wire. Injecting the positive electrostatic charges to the cancer cells includes accumulating the positive electrostatic charges on the inserted active part of the wire, and generating a positive electrostatic charge flow through the cancerous tumor responsive to accumulating the positive electrostatic charges on the inserted active part of the wire.
