Which one is serious, lung nodules or pulmonary hernias, cannot be judged in general, but needs to be analyzed according to its specific situation. The causes of lung nodules are numerous, if it is benign nodules or calcified nodules, the condition is not serious at this time, usually dynamic observation, treatment can be. However, if the lung nodules are caused by malignant tumors, their condition is much more serious than lung hernias, because patients with malignant tumors have a poor prognosis if they are not surgically removed early. Small lung blisters have no obvious effect on patients, and no special treatment is needed, the disease is not serious, but huge lung blisters are prone to rupture of lung blisters leading to the formation of pneumothorax, and patients will have obvious wheezing, shortness of breath, dyspnea, and in severe cases, respiratory failure or even shock can be seen, and at this time, the lung blisters are much more serious than the lung nodules.
