The best time for lung adenocarcinoma surgery is to operate immediately after discovery. The earlier the treatment, the lower the probability of peripheral invasion and distant metastasis of the tumor, and the better the prognosis. When lung adenocarcinoma is clinically detected, the patient should be hospitalized immediately and undergo radical resection through surgery if there are indications for surgery and the patient is in good physical condition. After early surgical resection, the invasion of the lesion to the surrounding area is relatively small, and there is no distant metastasis, and some patients can reach the clinical cure status, which reduces the impact on life expectancy. Some patients are in unstable condition after the detection of the lesion, they need to be hospitalized first to adjust their body to a good state, and then undergo surgical resection at the earliest possible time.
