7 Warning Signs of Lung Cancer You Shouldn’t Ignore
1. Persistent cough or changes in cough
If you have a cold, your cough should go away after a week or two, but if it persists over a long time, you should see your doctor. If you are a smoker or suffers from chronic cough, notice if there are any changes in your chronic cough, for example: coughing more frequently, deeper cough with a deeper or hoarse sound, coughing up blood or having more mucus than usual.
