Regardless of peripheral or central type, surgical treatment should be actively pursued as long as surgical conditions are available. This is the best treatment for lung cancer at present. Without pathological diagnosis, the diagnosis can still be confirmed by surgery. Thoracic surgeons strongly oppose to do puncture biopsy when surgery is possible, which has no more practical significance other than leading to contamination, metastasis. If there is distant metastasis, the effect of surgery is almost the same as not doing surgery, so surgery is usually not advocated, but individual patients, who have the condition to do local surgery, are still good for survival quality.
