Lung Cancer Symptoms

Lung cancer is the leading cause of cancer-related death in the United States. The majority of lung cancer cases are caused by cigarette smoking, killing upwards of 162,500 people in the U.S. alone in 2006.

Early diagnosis of lung cancer can be difficult because symptoms don't often present themselves aggressively until the disease is in advanced stages. If you experience any of the symptoms listed below, schedule a visit with your doctor to check them out.
