Ground-glass lung nodules that are relatively large or have a tendency to increase in size require surgery. Smaller glassy lung nodules usually do not require surgery. Ground glass lung nodules are ground glass nodules in the lungs that are usually found on a CT scan of the lungs. If it is a relatively small lung ground glass nodule, the diameter is less than 5mm, no surgery is needed, you need to go to the hospital regularly for review, pay attention to observe the changes of the nodule. If the nodule is large or has a tendency to become larger, and the diameter exceeds 8mm, surgical resection should be considered as soon as possible. Whether or not surgery is needed depends on the size, nature and location of the nodule, the history of smoking and the family genetic history of the tumor, etc. It is recommended to combine the diagnosis and treatment advice of professional doctors to choose the appropriate treatment plan. At the same time, patients are advised to quit smoking and stay away from environments with pollutants.
