Frosted glass nodule 3mm is mainly determined by the size and morphological changes of the nodule to determine the good and bad.
Generally, the ground glass nodule below 5mm is a smaller nodule, which is mostly benign, and is commonly found in lung nodules caused by lung inflammation and tuberculosis. If the ground glass nodule is 3mm, regular follow-up should be done to observe the changes in the shape and size of the nodule, and if the nodule disappears naturally, it means that it is benign. If the nodule grows rapidly and becomes larger, there is a possibility of malignant changes.
If the ground glass nodule 3mm in a short period of time to grow, become larger, and even occurred in the form of changes, such as burrs, lobulated, vacuolated, etc., should further cooperate with the doctor to improve the pathology of puncture and other tests, and timely exclusion of malignant changes possible.
Therefore, the possibility that the ground glass nodule 3mm is a benign nodule is relatively high, but does not completely exclude the possibility of malignant nodules, it is recommended to do a good job of dynamic follow-up observation.
