What does it mean if you cough up blood?

ANSWER

Coughing up blood (hemoptysis) can be a sign of a serious medical condition. Infections, cancer, and problems in blood vessels or in the lungs themselves can be responsible. Coughing up blood generally requires medical evaluation unless the hemoptysis is due to bronchitis.
