Heat therapy is a treatment method to selectively kill tumor cells by artificially increasing local or whole body temperature and using thermal effect to control widespread metastasis of tumor cells, which is a new tumor treatment means after surgery, radiotherapy, chemotherapy and biological therapy. It is a new tumor treatment method after surgery, radiotherapy, chemotherapy and biotherapy. It has positive efficacy, mild side effects and no serious damage to human body, which is called “green therapy” for tumor by World Health Organization. 1. Indications of thermotherapy 1.1 Palliative treatment for various types of middle and late stage tumors 1.2 Prevention of recurrence and metastasis of early stage tumors after surgery. 1.3 Analgesic treatment for intractable pain of late stage tumor. 1.4 Treatment for the regression of cancerous pleural fluid and ascites. 1.5 Cooperate with radiotherapy and chemotherapy, which can improve the therapeutic effect of radiotherapy and chemotherapy. 1.6 Patients who are not sensitive to radiotherapy, resistant to chemotherapy or cannot tolerate it. 1.7 It also has significant effect on chronic pelvic inflammatory disease, prostatitis, rheumatoid arthritis, etc. 2.The mechanism of microwave thermotherapy to kill tumor cells The ions and polar molecules of human tissues under the action of microwaves twist and rub, generating heat and increasing the temperature of tissues or the whole body. Heat therapy mainly destroys cell membrane structure, inhibits DNA, RNA and protein synthesis, leads to protein denaturation, impairs cell function and causes tumor cell death. 3.Advantages of UHR2000 microwave thermal therapy machine for tumor treatment 3.1 Safe, non-invasive, painless, easy and time-saving, patients only need to lie on their backs easily for 2 hours. 3.2 Implement computer control and management, real-time video monitoring and voice communication. 3.3 Wide indications: treatment can be implemented for patients who cannot tolerate surgery, radiotherapy and chemotherapy. 3.4 Enhance the efficacy of radiotherapy, reduce or reverse the occurrence of tumor drug resistance, and protect bone marrow. 3.5 Enhance the immune function of the body and inhibit the metastasis of tumors. The newly introduced UHR2000 high-power microwave thermal therapy machine in our department uses the new microwave beam technology patented by China and the United States, which has superior performance and exact treatment effect. It has wide indications and is painless, which is considered as “the sign of the arrival of medical spring”. It is believed that thermal therapy will bring the gospel to the majority of patients.
