Bloody sputum (hemoptysis) is a common symptom of which disease?

Explanation:
Hemoptysis happens when bleeding from the lung mucosa or vessels enters the airways. In pulmonary tuberculosis, caseating granulomas form cavities in the lung tissue that often erode into bronchi and nearby blood vessels. This erosion releases blood into the airway, producing coughing up blood. Because of this mechanism—cavitation with vascular erosion—TB is a classic and common cause of hemoptysis, especially in populations where TB is prevalent. Other conditions like pneumonia, COPD with bronchitis, or lung cancer can also cause bleeding, but they’re less characteristically linked to hemoptysis than TB.
