Pulmonary nodules a little large treatment recommendations are as follows: 1, lung nodules > 1cm in diameter: go to the respiratory specialist for further examination to clarify the nature of lung nodules, to see whether the nodules are benign or malignant, malignant found early most of the surgery can be removed directly, the problem is not particularly large, the patient does not need to be nervous; 2, lung nodules <5mm in diameter: solid nodules and pure ground glass nodules can be followed up in the local regular review CT; 3, lung nodules Diameter >5mm: ground glass nodules are recommended to be seen by a respiratory specialist to determine the malignancy of the nodule and the risk. If the risk is higher, further examination is recommended, and if the risk is lower, a follow-up can be scheduled. Pulmonary nodules are actually defined by imaging as focal, round-like, high-density shadows ≤3 cm in diameter found on imaging. More than 90% of nodules are benign and very few patients are malignant.
