WHO research data shows that lung cancer is the leading cause of cancer-related deaths worldwide. In the "Blue Book of Meinian Health Check-up Data in 2022", the detection rate of lung nodules is 55.9%. Some of them are transformed into lung tumors. Especially after the Covid-19 pandemic, the detection rate of lung nodules has an upward trend. Therefore, the development of bronchoscopic microwave ablation has broad application prospects.
