A black spot on the lungs is not serious. A black spot on the lungs, on imaging, generally refers to an imaging change in the lungs that appears as a pulmonary blister, which refers to the destruction of the walls of two adjacent alveoli, resulting in fusion with each other to form a single, larger cystic cavity. A single pulmonary herpes generally does not have a great impact on the human body, because the chance of rupture is rare, and there is no possibility of pneumothorax, and it will not cause any respiratory symptoms such as chest tightness, shortness of breath, coughing, coughing up sputum, fever, etc., and it does not have any impact on the human body, or its impact is extremely small, and therefore, it generally does not need to be treated. However, if the lung blisters are located at the edge of the pleura, there is a risk of rupture of the pleura, which may lead to pneumothorax. Surgical resection can be performed to reduce the risk of pneumothorax.
