The treatments for lung nodules include surgical treatment, anti-infection treatment, and clinical follow-up. Because each patient’s condition is different, it can not be said to be the best method, but need to choose the most suitable treatment plan for the patient under the guidance of the physician. 1. Surgery: Lung nodules can be benign lesions or malignant tumors. If the diameter of the nodule is larger than 15 mm, and the CT can see solid nodules with the manifestations of ground-glass shadow, burr sign, lobulation, pleural pulling, etc., it is considered as a high-risk nodule, and can be selected for surgical treatment after diagnosed as a malignant nodule by the hospital consultation. 2. Clinical follow-up: With the progress of science and changes in living environment, the detection rate of lung nodules is getting higher and higher. Usually, nodules smaller than 3 mm and multiple small nodules should be followed up clinically, and the examination can be repeated regularly to observe whether the nodules are growing or not, and the growth rate, and at least 3 years of clinical follow-up is needed. Once a pulmonary nodule is detected, the patient should seek prompt medical attention and be guided by a physician for the next step in the treatment program.
