Bloody sputum (spitting up blood or bloody mucus) can come from common forms of infection in the lungs and airways, such as acute bronchitis or pneumonia. Bloody sputum can also come from cancer of the lung. Whenever bloody sputum is present and cannot be attributed to a curable condition, a complete lung evaluation is warranted. Bloody sputum is also referred to as hemoptysis.
