There is no definitive value for the probability of a benign 6mm ground glass nodule, with benign nodules being the most common, but malignancy cannot be ruled out.
There is no authoritative literature or clinical case statistics that can give a specific value for the odds of a 6mm ground glass nodule being benign. Usually, the chance of benign nodules is relatively high for nodules less than 8mm. If there are no clear symptoms, it is recommended to follow up the nodules, and review the nodules in 6~12 months, and no treatment is needed if there is no change in the size of the nodules.
However, malignancy cannot be ruled out, especially in the early stage of carcinoma in situ or metastatic lesions, and 6mm may also be malignant. The diagnosis can only be made clearly according to the final pathological examination results, and it is impossible to make a diagnosis by the size.
Therefore, it is recommended to consult a doctor in time for further examination to clarify the specific nature.
