Lung ground glass nodules can also be reviewed when they are 10 days short of 6 months. Once a pulmonary ground-glass nodule is detected, it is generally recommended to review it once every three to six months, but the review period can be shortened if the nodule grows faster or if symptoms such as coughing, coughing up sputum, or wasting occur. If no abnormality is found after 6 months, the examination can be repeated at an interval of 6 months, and if there is still no abnormal reaction, the examination can be repeated at an interval of one year. The items for review of pulmonary ground-glass nodules are generally chest scanning CT and chest enhancement CT, through which the imaging examination can clarify whether the nodule has increased in size and whether the morphology has changed, and if there is a suspicion of malignant change of the nodule, it is also possible to improve the tumor marker test, percutaneous lung puncture biopsy and other tests, which can help to clarify the nature of the nodule. The discovery of pulmonary ground-glass nodules should be taken seriously, and if cancerous tendency is found in the process of review, it is recommended to follow the doctor’s instructions for timely surgical resection, disease progression and endangerment of life and health.
