Image-guided tumor microwave ablation therapy is a new minimally invasive, safe and effective technique for in situ tumor inactivation developed in the past 20 years. This method is to puncture the tumor directly through the skin under the monitoring and guidance of image, accurately place one or several needle microwave emitters into the tumor, and start emitting microwaves, which will form a high heat field in the tumor and its surrounding area, and when the temperature of the edge rises by 60 degrees, it will cause necrosis of the tumor cells, and achieve the purpose of killing the whole tumor. This treatment has the advantages of being minimally invasive, safe, precise efficacy, short treatment time, mild side effects and complications, and fast recovery after surgery. This treatment is now widely used in many solid tumors such as liver cancer, lung cancer, kidney cancer, adrenal gland tumor, breast cancer and some benign tumors such as uterine fibroids and so on, and its efficacy is clinically proved to be comparable with radical surgical resection.
