Mixed ground glass nodules have the potential for lung cancer, but there is no specific value for this and the diagnosis should be confirmed based on further tests to clarify the nature of the nodule. Mixed ground-glass nodules are a special type of ground-glass nodule with both solid and ground-glass components and have a high rate of carcinoma, which may be an infection, a benign tumor, or a malignant tumor. The cancer rate is closely related to the size of the mixed ground glass nodule and the amount of solid component, the more solid component, the larger the nodule, and the cancer rate increases accordingly. It is suggested that close observation and high attention should be paid, and follow-up for three months, if the nodule does not shrink or shows signs of increasing, surgery is generally recommended, and early surgery can be curative.
