Isotope therapy is a technological medical treatment using radioactive isotopes and radioactive elements that decay to produce rays for treatment, mainly for the treatment of malignant tumors and cancer. The cost of an isotope treatment in a general tertiary hospital is about 2,300 RMB, and the price of isotope treatment in a tertiary hospital in a first-tier city can reach more than 3,000 RMB, and the cost of treating hyperthyroidism with isotopes to achieve the effect of eradication is 8,000-16,000 RMB. If it is used for malignant tumor or cancer radiotherapy, the cost can reach about 13,000 RMB. Despite the high price, the effect of isotope treatment is also very obvious.
