Infections: Bacterial, viral, and fungal infections can lead to lung damage, such as pneumonia or bronchitis. 2. Tobacco Smoke: Smoking is a leading cause of lung damage, including chronic obstructive pulmonary disease (COPD) and lung cancer. 3. Air Pollution: Exposure to polluted air, particularly with high levels of particulate matter and toxic gases, can harm lung tissue. 4. Occupational Hazards: Workers in certain industries may be exposed to harmful substances like asbestos, silica, or chemicals, which can cause lung diseases. 5. Radiation Therapy: Lung tissue can be damaged by radiation used to treat cancers in the chest area. 6. Drugs and Medications: Some drugs, including certain chemotherapy agents, can cause lung damage as a side effect. 7. Autoimmune Diseases: Conditions like sarcoidosis or lupus can lead to inflammation and damage in the lungs. 8. Genetic Disorders: Some inherited conditions, such as cystic fibrosis, can cause progressive lung damage.
