What are the advantages of radiofrequency needle ablation for tumor treatment?

Radiofrequency ablation has a direct destructive effect on tumor tissue, destroying and cutting tumors. The maximum temperature of radiofrequency ablation for local tumor treatment can be over 95℃, and the surrounding temperature can also be up to 60℃. It can not only rapidly treat huge tumors, but also tumors with a diameter of less than 3cm. It plays a coagulation effect on peripheral blood vessels, so that they cannot continue to supply blood to the tumor, and forms a reaction zone between normal tissue and cancer tissue to wrap the tumor. It can prevent tumor metastasis to some extent, but has little effect on surrounding tissues.
