Hyperthermia is a physical method to treat tumor by heating, using the thermal effect generated by the precipitation of relevant physical energy in tumor tissues to heat the tissues to a temperature that can kill tumor cells, so as to achieve a method that not only destroys tumor cells but also does not damage (or less affect) normal tissues. The Department of Oncology of Beijing Hospital has carried out BSD-2000 phased-array focused thermal therapy for tumor treatment in September 2009. It can control the temperature of tumor lesion between 43-45℃ by using phased-array technology and real-time temperature measurement. Treatment characteristics (1) Non-invasive treatment (2) Heat therapy can be administered alone or combined with chemotherapy and radiotherapy to increase the efficacy of chemotherapy and radiotherapy (3) Painless treatment and short treatment time; generally each patient’s treatment time is about one hour (4) Can inactivate residual tumor tissues for many times (5) Non-toxic to normal organs and tissue cells, and will not cause adverse reactions such as bone marrow suppression and hair loss Heat therapy indications: 1. Cancer pain Contraindications: 1. Pacemaker or heart electrode implantation 2. Patients with serious cardiovascular disease 3.
