Whether an 8 mm sub-solid ground-glass nodule can be cured after excision needs to be analyzed in relation to the status of the lesion. Tumors with benign or low malignancy on pathological examination are basically curable after surgical resection; most of the tumors with high malignancy on examination cannot be completely cured by surgery alone. A large proportion of 8 mm sub-solid ground-glass nodules can be completely cured after resection of benign tumors or well-differentiated malignant tumors, with clean resection of peripheral tissue lesions and no residual tumor cells after surgery. The postoperative pathological findings of 8 mm sub-solid ground-glass nodule are low differentiated and highly malignant, and the simple surgical resection of the part will have the probability of recurrence and metastasis, which may not necessarily be completely cured. If necessary, radiotherapy and targeted therapy should be continued to control and minimize the probability of recurrence. After the operation, we should pay attention to closely observe the recovery of the operation area, and go to the hospital for regular review, usually pay attention to adjusting the diet, enhance the physical quality, and try to avoid recurrence, even after recurrence, we should do early detection and early treatment, the prognosis will be relatively good.
