Do you have a cough that's lingered for a month or longer? It's time to schedule an appointment with your doctor. One of the most common symptoms of lung cancer is a persistent, nagging cough. The American Cancer Society estimates that in 2018, there will be more than 234,000 new cases of lung and bronchus cancer in the U.S.—with more than 154,000 of those patients losing their life to the disease. Don't be a statistic. When caught early, this cancer has a high rate of remission.
