If there are no symptoms, we should review the condition regularly; if there is a risk of malignant changes, we should further improve the biopsy and other related examinations and timely surgery. 1. Situations requiring regular review: most of the ground-glass nodules are the result of local fibrosis caused by chronic inflammation or tuberculosis, and the imaging results left after the recovery of the disease. There are no symptoms, usually regular review, if gradually become smaller or disappear, or the size does not change, usually do not need special treatment. 2. Risk of malignancy: When the ground glass nodule becomes larger or larger than 10mm, and the corresponding symptoms such as chest pain, chest tightness, dyspnea and so on continue to be unrelieved, then the possibility of malignancy is considered. At this time, it is necessary to further improve the pathological biopsy, for the diagnosis of patients, or nodule growth faster patients, should be taken as soon as possible surgical treatment. For malignant tumors, radiotherapy and chemotherapy should also be taken as treatment measures. Avoid mental stress when detecting ground-glass nodules, consult a doctor in time, and follow the doctor’s advice to decide whether to take surgery and other programs.
