Abstract: A method for detecting cancer involved lymph nodes. The method includes placing a pH-sensing paper inside a needle of an injection syringe, filling the injection syringe with a buffer solution, putting the pH-sensing paper in contact with lymphatic fluid of a lymph node by inserting the needle of the injection syringe inside the lymph node, putting the lymphatic fluid in interaction with the buffer solution by injecting the buffer solution into the lymph node utilizing the injection syringe, and detecting that the lymph node as a cancer involved lymph node if color of the pH-sensing paper is changed to an acidic-range pH color.

Abstract: A method for non-invasive detecting and tracing cancer.

Abstract: A method for destroying a cancerous tumor. The method includes putting two electrodes of an electrical probe in contact with a portion of the cancerous tumor, plotting an impedance phase diagram by measuring a set of electrical impedance phase values from the portion of the cancerous tumor at end of a respective set of pre-determined time steps, destroying cancer cells of the portion of the cancerous tumor within each time step of the respective set of pre-determined time steps by electrolyzing peripheral medium surrounding the cancer cells of the portion of the cancerous tumor by applying a direct current (DC) voltage between the two electrodes, and stopping destroying of the cancer cells responsive to a complete destruction of the portion of the cancerous tumor, where the complete destruction includes obtaining a positive slope of the impedance phase diagram (IPS).
