For pure ground-glass nodules in the lungs, previous chest CT can be compared, and if there is enlargement, surgery is often recommended; if there is no enlargement or no previous CT, follow-up is often recommended. For pure ground-glass nodules, if there is a history of previous CT, previous CT can be compared, and if there is enlargement, biopsy or direct surgical resection is often recommended. If there is no previous CT, the treatment plan can be based on the size of the pure ground glass nodule. If there is no previous chest CT for comparison, follow-up observation can be performed first, such as pure ground glass nodules less than or equal to 5mm, usually 6 months follow-up, and then if there is no change, then annual chest CT follow-up will be performed. For pure ground glass nodules larger than 5 mm, follow-up is usually 3 months, followed by annual follow-up if there is no change. It is recommended that people with pure ground-glass nodules in the lungs seek prompt medical attention and treatment under the guidance of a medical professional.
