The scheme adopts a cold-hot alternative ablation treatment scheme to improve the tumor ablation treatment effect. Experiments show that the survival rate of the tumor cells is much lower than that under the condition of single cold or single heat by adopting cold and hot alternation to stimulate the breast cancer cells, so that the cold and hot alternation can cause more serious tumor cell damage and is a more effective tumor killing means. The physical and chemical properties of the tumor cells after the low-temperature stimulation process are changed, and the thermal sensitivity of the tumor cells is different when the thermotherapy is carried out, so that the killing rate of the tumor cells is improved, the immune response of an organism is improved, and the condition after healing is better.
