Ground glass nodules in the lungs should be referred to either thoracic surgery for examination or respiratory medicine, both of which can identify the specific cause of the condition and provide prompt treatment. Doctors in thoracic surgery or respiratory medicine will perform selective tests to determine the nature of the nodule and the presence of lung infections, pulmonary vasculitis, lung tumors, and other diseases, depending on the situation. Lung if the ground glass nodule does not meet the criteria for resection, close follow-up can be done. Chest CT can be done once in six months or once in a year to observe changes in the nodule. If the nodule meets the criteria for resection, it should be seen in the thoracic surgery department for treatment. If ground-glass nodules are found in the lungs, a thoracic surgeon or respiratory physician can be asked to assist in the diagnosis and treatment to clarify the nature of the nodules, and thoracoscopic surgery can be performed if necessary.
