If you don't smoke, there's very little chance a nagging cough is a sign of cancer. Usually, it's caused by postnasal drip, asthma, acid reflux, or an infection. But if yours doesn't go away or you cough up blood -- especially if you are a smoker -- see your doctor. She may test mucus from your lungs or do a chest X-ray to check for lung cancer.
