Which lung condition is a malignant tumor arising from the lungs and bronchi?

• A. Emphysema
• B. URI
• C. Lung Cancer
• D. TB

Answer: (C)

Lung cancer is a malignant tumor that begins in the lungs or bronchial tubes. It’s a cancerous growth arising from lung tissue, often starting in the lining of the airways (the bronchial epithelium). This distinguishes it from other lung-related conditions: emphysema is a chronic disease where the walls of the air sacs are damaged, leading to shortness of breath; a URI is an infection of the upper airway; and TB is an infectious disease caused by Mycobacterium tuberculosis that forms granulomas in the lungs. Only a malignant neoplasm of the lungs and bronchi fits the description of a cancerous tumor originating in those structures.
