Microwave ablation surgery for liver cancer has certain therapeutic effects. Its principle of action is to kill liver cancer tumors by inserting a puncture needle into the interior of liver cancer tumors and causing degeneration and necrosis of liver cancer tissues and liver cells through heat energy. Strictly speaking, if the diagnosis of liver cancer is clear, if surgical resection is possible, surgical resection is still recommended as much as possible, while other treatment methods such as microwave ablation and radiofrequency ablation are generally secondary. If there are multiple tumors inside the liver and surgery cannot achieve complete cure, other treatment methods such as microwave ablation can be used for treatment. If there is a new mass formation, microwave ablation is also needed.
