1. Heat therapy alone For patients with advanced tumor who have relapsed after radiotherapy, chemotherapy or surgery, and who are not suitable to continue the above treatments, heat therapy alone can be used for palliative treatment. Heat therapy can relieve the intractable pain of advanced tumors and improve the quality of life of patients. Direct heat therapy for superficial tumors such as breast cancer and skin cancer can effectively control the development of tumors. For tumors with skin rupture and pelvic inflammation, it can achieve twice the effect with half the effort (inhibit tumor and control inflammation, etc.). 2. Combined heat therapy heat therapy combined with chemotherapy, i.e. thermal chemotherapy, can improve the concentration of drugs in tumor and enhance the anti-tumor effect; meanwhile, it can reduce the toxic effect of chemotherapy drugs on unheated normal tissues; the combination of the two can also help prevent and delay the generation of drug resistance. 3.Thermal therapy combined with radiotherapy: tumor cells located in the central part of tumor are in hypoxic state, insensitive to radiation and cannot be completely killed after radiotherapy, which often become the root cause of tumor recurrence, while the effect of thermotherapy is especially strong for such sub-tumor cells; especially the S-phase cells resistant to radiotherapy are especially easy to be killed by high heat, therefore, thermotherapy can make up for the shortage of radiotherapy, and the combined use can improve the efficacy.
