What are the possible causes of shadows on the lungs?

The reasons for the shadows on the lungs are very complicated. They are often caused by lung diseases, which are closely related to the patient's living habits, such as frequent smoking, staying up late, and working environment. Once there is a problem with the lungs, a detailed examination is required to accurately find the cause, otherwise it will be impossible to treat the symptoms. So what are the possibilities for shadows on the lungs?

First, what are the possibilities for shadows on the lungs ? Lung infection. These mainly include pneumonia, tuberculosis, bronchiectasis, pulmonary fibrosis, interstitial pneumonia and pulmonary aspergillosis. In addition to lung shadows on X-ray examinations, these diseases are often accompanied by other symptoms, and it is not difficult to make a clear diagnosis clinically. pneumonia. It is a lung infection caused by pathogenic microorganisms (bacteria, mycoplasma, chlamydia, viruses, etc.). In addition to lung shadows on X-ray examinations, patients also have symptoms such as cough, sputum, fever, chest tightness, fatigue, and difficulty breathing. In severe cases, infectious toxic shock may even occur.

second. tuberculosis. It is a lung infection caused by a special bacterium, Mycobacterium tuberculosis, and its incidence has been increasing in recent years. Common locations are the apex, posterior segment of the upper lung and dorsal segment of the lower lobe on both sides. The shadows appear as scattered flakes, which may contain calcification foci, sometimes spherical lesions or miliary lesions. In rare cases, the entire lobe of one lung may be affected, forming a so-called "destroyed lung."

Third, bronchiectasis . It is a structural change caused by irreversible damage to the bronchus due to external forces. Symptoms usually include coughing, difficulty breathing, and coughing up blood, and it is also a relatively dangerous disease.

What are the possibilities for shadows on the lungs ? Lung tumor. The second type of disease that causes "lung shadows" is lung tumors. However, lung tumors do not mean lung cancer, nor do they mean an incurable disease. The panic about "lung shadows" mainly comes from lung cancer. This disease is common in middle-aged and elderly people. The lung shadows are mostly spherical, and careful observation shows that the edges are lobed. Some patients have "burrs" on the edges of the shadows, while some patients show flake shadows similar to pneumonia. Generally speaking, patients will experience symptoms such as irritating cough, bloody sputum, chest pain, weight loss, hoarseness, and choking when drinking water. Chest CT examination, sputum test, fiberoptic bronchoscopy or CT-guided puncture biopsy can confirm the diagnosis.
