A 5mm ground glass lung nodule is not very serious.
Frosted glass lung nodules are generally considered to be calcified foci left after the cure of environmental air pollution, lung infection, tuberculosis, etc. They belong to the abnormal proliferation of lung tissues, and most of them are benign nodules. If it is a 5mm ground glass lung nodule, the nodule is relatively small and not very serious. However, it is important to follow up and observe the nodule. Chest CT can be performed after 3 or 6 months to keep track of the nodule size and morphologic changes.
If you find that the 5mm ground glass lung nodule suddenly increases in size, you should cooperate with your doctor as soon as possible to carry out puncture pathology examination to clarify the nature of the nodule, and to exclude the possibility of malignant nodules at an early stage.
Therefore, once the CT examination found 5mm ground glass lung nodules in the lungs, it is necessary to follow the doctor’s instructions for regular review, find abnormalities, and take timely treatment measures.
