The survival time of 8 mm milled glass nodules is related to the type of pathology, treatment effect, patient’s physical condition and other factors, which need to be considered comprehensively, and it is recommended to consult the doctor promptly when finding milled glass nodules in the lungs. 8 mm milled glass nodules can be categorized into benign nodules and malignant nodules. If it is a benign nodule, such as pneumonia, tuberculosis and other diseases, usually after active treatment. Patients with this kind of ground glass nodule will not affect their life expectancy and can work and live as normal after treatment. If the 8 mm ground glass nodule is malignant nodule, such as lung cancer, for early non-small cell lung cancer patients, the 5-year survival rate prognosis is better, probably about 70%~80%, and the clinical prognosis of patients with advanced stage is worse. For early-stage small cell lung cancer patients, the 5-year survival rate is good, probably about 50%, but the prognosis is relatively poor compared to non-small cell lung cancer. Therefore, patients with 8-millimeter ground-glass nodules should go to the hospital in time to find out the cause of the disease and treat the cause, so as to avoid delaying the disease.
