What increases my risk for hemothorax, a pleural cavity disorder?

Chest trauma increases the risk for hemothorax (bleeding into the pleural cavity). Other possible risk factors include blunt or penetrating traumas to the chest or lung, pleural cancer, and blood clotting problems. Other risks are heart or chest surgery, use of a venous catheter, and death of lung tissue. A hemothorax may also be a complication from an infection (like pneumonia) or other lung disease (like tuberculosis).
