What are the most common diseases of the bronchial and pulmonary system?

The most common bronchopulmonary diseases include: 1. Pneumonia: a lung infection caused by bacteria, viruses, or fungi, with main symptoms including cough, chest pain, shortness of breath, and fever. 2. Bronchial asthma: a chronic respiratory disease triggered by genetic factors or exposure to allergens, characterized by wheezing, difficulty breathing, and coughing. 3. Chronic bronchitis and chronic obstructive pulmonary disease (COPD): both are chronic nonspecific inflammations; main symptoms include shortness of breath, cough, and sputum production. Long-term smoking is the primary risk factor. 4. Tuberculosis: an infectious disease caused by Mycobacterium tuberculosis, with symptoms such as prolonged cough, sputum production, fever, and weight loss. 5. Lung cancer: a malignant tumor whose main symptoms include cough, sputum production, difficulty breathing, and chest pain. Treatment methods for these diseases vary, and early detection and treatment are crucial for effective disease management. If you experience any related symptoms, it is recommended to seek medical evaluation and treatment promptly.
