The application mode can be applied to the surface of the skin of a human body or in the human body, such as a cardiac defibrillator, a peripheral nerve and muscle stimulator, a tumor resection device and the like; 2) electric wave sources emit electric waves, such as RF wave sources and microwave sources, which deliver energy to the body by radiation or induction. In this mode, there is no electrical energy conduction between the energy source and the body.

The tumor treating electric field is one low strength, medium and high frequency alternating electric field and can treat tumor via interfering the mitosis process of tumor cell. Research shows that the tumor electric field treatment method has obvious effect in treating tumors such as glioblastoma, non-small cell lung cancer, melanoma and the like, can prolong the life of a patient, and has small side effect.

The tumor treatment electric field is applied to the tissue region where the tumor is located through an external electrode, and the electric field is applied to the tumor in a capacitive coupling mode. The electric field electrode for treating tumor is applied to the surface of the skin of a patient to treat the patient for a long time, and the continuous application time of the electric field electrode is 2-4 days.
