Abstract: A system for real-time detecting cancer by analyzing unprocessed blood. The system includes a sensor, an electrical stimulator-analyzer connected to the sensor, and a processing unit connected to the electrical stimulator-analyzer. The sensor includes three electrodes including a working electrode, a counter electrode, and a reference electrode configured to be put in contact with an unprocessed blood sample. The processing unit is configured to perform a method. The method includes applying a set of voltages between the reference electrode and the working electrode utilizing the stimulator-analyzer, measuring a produced set of currents between the counter electrode and the working electrode utilizing the stimulator-analyzer, measuring a level of a ratio of low-density neutrophils (LDNs) to high-density neutrophils (HDNs) in the unprocessed blood sample by measuring a maximum current of the measured set of currents, and detecting a cancer disease if the measured maximum current is less than a threshold value.

Abstract: A method for detecting cancerous status of a biological sample. The method includes calculating a charge transfer resistance (Rct) of an electrochemical impedance spectroscopy (EIS) associated with lipid secretion of a biological sample, detecting a cancerous state for the biological sample responsive to the calculated Rct being equal to or more than a threshold value, and detecting a normal state for the biological sample responsive to the calculated Rct being less than the threshold value. The biological sample includes a biological sample suspected to be cancerous.
