The main types of liver cancer ablation are cryoablation, microwave ablation and radiofrequency ablation. There are also some tumors with relatively dangerous location, which can be ablated by nano-knife. 1. Cryoablation: Through the heat absorption and evaporation of liquid refrigerant, the heat of cancer cells is taken away. Cryoablation facilitates the doctor’s operation, shortens the operation time and improves the treatment effectively. 2. Microwave ablation: locate the core of liver cancer and then insert the microwave ablation needle. The high temperature will destroy the liver cancer cells and achieve the purpose of ablation. 3. Radiofrequency ablation: locate the core of liver cancer and then insert the radiofrequency ablation needle. The high temperature generated by the radiofrequency needle will kill the cancer cells. 4. Nano knife ablation: it is not temperature ablation and can be chosen for relatively dangerous parts. It is recommended to go to regular hospitals for liver cancer and choose the ablation method according to the doctor’s judgment of the patient’s condition.
