As a minimally invasive treatment, the main drawback of lung cancer ablation surgery is that some lung cancers are not suitable for ablation treatment, that is, lung cancer ablation treatment has strict contraindications, and the common contraindications include: 1. Those with serious and other risks; 5. Those with diffuse metastatic lesions in the lung; 6. When there is a pacemaker in the patient’s body, radiofrequency ablation treatment cannot be done. There will be complications after lung cancer ablation, even serious complications. The general complications are not so traumatic for lung cancer patients, such as pneumothorax caused during surgery, a small amount of hemoptysis is not serious, and sometimes there is the presence of hemoptysis, which requires interventional embolization to interfere. In addition, infection of the ablated part of the tumor can occur after ablation. Even some patients can develop pleuro-tracheal fistula, which is a more serious complication. Although ablation therapy is a very good minimally invasive treatment for lung cancer, it also has disadvantages.
