Patients with pulmonary ground-glass nodules need to consider surgical treatment if the diameter of the nodule is more than 8mm. Patients with ground-glass nodules in the lungs usually do not have any discomfort, and are often found during physical examination by chest CT. If the diameter of the ground-glass nodules in the lungs is greater than 8mm, and whether there is lobarization of the lung nodules morphologically, and whether there are any burrs and these features, because these features often suggest that the malignant tumors are relatively high, and timely surgical treatment is needed. For patients with pulmonary ground-glass nodules with a diameter of less than 8mm, observation is sufficient, and chest CT should be repeated every 3-6 months to see the changes in the diameter of the pulmonary nodule shadow. Patients with ground glass nodules in the lungs need to pay attention to the review of the nodule changes. When the nodules are found to be enlarged, they should be treated in time so as not to miss the best time for treatment.
