Ground glass nodule 1cm two months did not disappear, if accompanied by clinical symptoms, can be further bronchoscopy or lung puncture examination, in order to clarify the nature of the nodule.
When there is a 1cm ground-glass nodule, and the nodule does not disappear in two months, the next step of treatment should be judged according to the actual clinical situation. If there is a possibility of malignant nodule, further examination related to early lung cancer should be performed to clarify its nature. If malignant nodules are diagnosed, timely surgical treatment, including thoracoscopic lobectomy or partial lung resection, should be performed.
If it is observed from imaging and clinical symptoms that a ground-glass lung nodule is more likely to be an inflammatory nodule, anti-infective treatment and follow-up are the mainstay.
