The present invention discloses a cancer therapy instrument with functions of pertinence function recovery treatment, preventing cancer generation and cancer diffusion transfer, clinical therapy and rehabilitation for cancer. The present invention comprises a friction joint of direct current cutting and extrusion, a friction joint of static friction in low frequency or middle frequency, a drug cloth, a radio frequency, the microwave and an ultrasound treatment device. Through combination of friction heating, muscle rubbing with electrical stimulation and deep layer heating, combination of local transversal administration and local medicine injection intervention, function of cancer surrounding area is recovered. According to therapy method and theory for serious disease in the specification, mutual restriction between function decreasing and structure damage is the whole reason for cancer generation. The cancer therapy instrument applies advanced therapy technology for function recovery of combination of physical method and chemical method, which is combined with surgery, radiotherapy, local chemotherapy, anti damage treatment, therefore the whole etiology treatment is formed, through which purpose for healing cancer can be realized.
