Surgical resection is the main and primary treatment for lung cancer. The common surgical procedures can be classified as wedge resection, segmental resection, lobectomy, combined lobectomy, bronchial sleeve lobectomy and total pneumonectomy. Not every tumor patient can receive surgical treatment. In order to have surgery, one must meet the indications for surgery without absolute contraindications for surgery. The main contraindications to lung cancer surgery are as follows: 1. Stage IIIB and IV patients with definite clinical diagnosis. 2. 2.Patients with severe cardiac and pulmonary dysfunction. 3. Repeated angina attacks, especially frequent attacks or myocardial infarction in the past 3 months. 4.Patients with a history of cerebrovascular accident within the past 3 months; 5.Patients with contraindications to anesthesia or other contraindications to surgery. 6. Those with severe cachexia or other major organ functions that cannot tolerate surgery. After surgery and other treatment measures, most of the disease is likely to be cured, postoperative patients should pay attention to adjust the mentality, establish confidence, and actively cooperate with the treatment, is a good help to recovery. After the catheter is removed, most patients (except whole lung patients) can moderately get out of bed after the operation. Early activities can reduce the occurrence of pulmonary embolism, cerebral infarction or heart attack. Especially for elderly and obese patients, postoperative pulmonary embolism is prone to occur, and the latter can lead to sudden death, so these patients should pay more attention to early bed activity. The postoperative diet of lung cancer should be varied and easy to digest, including milk, eggs, fish, meat, poultry and bean products with high quality protein, honey and sugar-rich rice and noodles to supplement calories, vitamin-rich fruits, peanut rice and fresh vegetables such as carrots, tomatoes and cabbage.
