Although everyone's living standard has improved, we also attach great importance to our health. Both institutions and individuals go to the hospital for physical examination every year. Chest X-ray is the most important item in our physical examination. From the chest X-ray, we can see whether there are large blood vessels and lesions in the lungs and heart. The lung is an important respiratory organ of our human body. The main function of lung is gas exchange. The human body breathes oxygen through the lungs, and then discharges carbon dioxide discharged from veins through the exchange of qi and blood.
In addition to the respiratory function, the lung also has the function of regulating human blood circulation, which not only provides oxygen for our body, but also ensures the normal operation of the body. Therefore, the lung is closely related to respiration, blood vessels and blood, and it is an indispensable organ in our province. We can't see any shadow in the normal lung film, so we should pay attention to the shadow of the lung during the physical examination and filming. What can cause lung shadow? I have the following analysis for your reference.
0 1, chronic pneumonia There are many smokers in China. Long-term smoking is very bad for lung function, which will cause lung diseases and respiratory diseases. Long-term smoking can cause dyspnea, cough with excessive phlegm, chest tightness, pain and other symptoms. At this time, when we take a chest film of the lung, there will be a vague shadow on the film, which is a manifestation of inflammation in the lung. If you are an old smoker who has smoked for decades, you should consider whether it is a pathological change of lung cancer.
02. Tuberculosis In the era of underdeveloped medicine, the mortality rate of tuberculosis is very high. With the development of medicine, tuberculosis can be prevented by tuberculosis vaccine. However, there is no absolute prevention. Tuberculosis is caused by mycobacteria, which is highly contagious. Patients will have symptoms such as cough, expectoration, fever and hemoptysis. Long-term pulmonary tuberculosis patients will cause flaky shadows in the lungs, and sometimes severe patients will have spherical shadows throughout the lungs. Tuberculosis is also one of the diseases that cause lung cancer, so we must pay attention to it.
03, there is virus and bacteria infection in the lungs, and there is infection in the lungs, which is generally caused by virus and bacteria. Most patients will have symptoms such as cough and expectoration. The severity of infection is different from the image presented by chest X-ray. In patients with mild infection, the shadow area on chest film will be very small, and fuzzy mottled shadows will appear on lung film. In patients with severe infection, a large area of shadow will appear on the chest film of the lung, and different color film effects will appear.
04, the emergence of lung cancer, lung cancer is also one of the main diseases that threaten human life in recent years. Patients will have symptoms such as cough, chest tightness and hemoptysis in the early stage. The early manifestations of lung cancer on chest radiographs are not obvious, but there are general lung shadows, which often do not attract the attention of patients. In the middle and late stage of lung cancer, there will be masses on chest radiograph, with different sizes and shapes. If this happens, please go to a regular hospital immediately for further examination and treatment to maintain the normal operation of our body. No matter what kind of lung shadow appears, we should pay attention to it, don't delay the development of the disease, and cherish life.
