The need for surgical resection of pulmonary ground-glass nodules is related not only to size, but also to density and relationship with surrounding tissues, and requires comprehensive consideration. If a ground-glass nodule is larger than 1 cm and has a solid component within it, it needs to be seen in a hospital for prompt surgical treatment under a doctor’s supervision. If the nodule is smaller than 6 mm and there is no solid component in the pure ground glass nodule, it is recommended to undergo examination such as chest CT every 6 months or 1 year to observe whether there are any other lesions. In addition, if the nodule is larger than 6 millimeters and also has a solid component within it, and has a family history of the disease, it is necessary to go to the hospital for a pathological biopsy to clarify the nature of the disease and then timely treatment.
