Recognizing the Early Indicators of Lung Cancer

4. Coughing Up Blood

Coughing up blood is a common symptom of lung cancer; even the smallest amount of blood can indicate a problem. One of the first things a doctor will determine is whether the blood truly came from the lungs or if it originated somewhere else, like in the upper airway of the mouth or nose. If it is indeed coming from the lungs, the goal is to stop the bleeding and protect the airway. In advanced cancer cases, this may include placing a breathing tube.
