ECT starts to work through the metabolic system of the tumour cell and has a positive influence on the immunisation process.  For this purpose, electrical poles (electrodes) which cause low voltage direct current to flow through the area are attached in and on the tumorous areas. The electrical resistance of the tumour cells is reduced so that the low voltage current can only focus to cause damage to these but not to the healthy tissue. In this manner, growths are caused to gradually die off in a sterile state (aseptic bionecrosis), often in a single session with a duration of up to three hours. The tissue is rejected by the healthy body by degrees and/or degraded by the immune system’s scavenger cells (phagocytes). During a treatment, an electrical field is created and loaded particles (ions) are drawn to the respective poles (electrolysis), for example Na+ and H+ to the cathode (negative pole) and Cl- to the anode (positive pole). This results in the creation of an alkaline environment around the cathode and an acidic environment around the anode. The Ph values are in both cases far from the physiological area and have a destructive effect on the tissue. The membrane potentials alter when the electrolytic environment in and around the cells is changed. The membrane becomes perforated in the accelerated ion flow and disturbances in the metabolic functions and intercellular structures take place. The cell becomes vulnerable to immune cells, because these are no longer electrically repelled. At the same time, tumour antigens are released and increasingly recognised by the attracted immune cells. A renewed creation of metastases is effectively counteracted because the current is already active during the attachment of the electrodes and any tumour cells which may be released are held in the electrical field.
