Electrochemical therapy of cancerous tumors based on intra-therapeutical impedance monitoring

A method for destroying a cancerous tumor, comprising:

• 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 a respective set of pre-determined time steps by applying an alternating current (AC) voltage in a sweeping range of frequencies to the two electrodes at end of each time step of the respective set of pre-determined time steps utilizing an impedance analyzer device;
• 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, the electrolyzing peripheral medium comprising applying a direct current (DC) voltage between the two electrodes utilizing a DC voltage generator;
• and
• stopping destroying of the cancer cells responsive to a complete destruction of the portion of the cancerous tumor, the complete destruction comprising obtaining a positive slope of the impedance phase diagram (IPS) by analyzing the IPS at end of each time step,
• wherein destroying cancer cells of the portion of the cancerous tumor within each time step, plotting the impedance phase diagram at end of each time step, and analyzing the IPS at end of each time step are done in a cycle iteratively after each other.
