What is the principle of liver cancer radiofrequency ablation needle?

Hello, the principle of radiofrequency ablation or microwave ablation of liver cancer is to use the thermal effect of microwave or radiofrequency to heat the liver tissue through the oscillation of polar molecules in the tissue, especially water molecules, thus causing thermal coagulation in the target area, or to burn the tumor in common sense, which can achieve radical curative effect comparable to liver cancer resection and liver transplantation
