What are the mass shadows in the lungs?

Lung cancer is a tumor disease with a very high mortality rate in our country. Basically, hundreds of thousands of people die from lung cancer every year. Especially for some men, long-term smoking or air quality checks are also one of the reasons. So what are the mass shadows in the lungs?

The first are lung infectious diseases: including pneumonia (accompanied by cough, sputum, fever, chest tightness, fatigue, difficulty breathing, etc.), tuberculosis (often with cough, sputum and hemoptysis, as well as low fever in the afternoon, fatigue, night sweats, loss of appetite, etc.), bronchiectasis (common symptoms are long-term coughing up thick sputum and hemoptysis), pulmonary aspergillosis (most have no systemic symptoms, a few may have coughing up blood and cough), etc.

The second type is lung nodules: sometimes coughing, coughing up a small amount of sputum, a small amount of hemoptysis, frequent fatigue, fever, night sweats, loss of appetite, weight loss, etc. When the lesions are extensive, chest tightness, shortness of breath, and even cyanosis may occur. The condition may be aggravated by concurrent infection, emphysema, cor pulmonale, etc.

The third category is congenital pulmonary malformations: mainly including lung cysts (more common in male children and young adults), pulmonary hamartomas (generally asymptomatic), pulmonary sequestration (congenital pulmonary malformations), etc.

The fourth category is lung tumors: including lung tumors (common in middle-aged and elderly people, with symptoms such as irritating cough, bloody sputum, chest pain, weight loss, hoarseness, and choking when drinking water), lung metastatic cancer (malignant tumors in other parts of the body metastasize to the lungs, and most patients are asymptomatic), pulmonary pseudotumor (most patients have a history of pneumonia, and most of them do not have any symptoms when lung shadows are found, and sometimes it is difficult to distinguish from lung cancer), etc.
