Here is a list of signs that give you the message that you might have lung cancer. Here are some signs listed below. Did you know any of the symptom?
1. Shortness of breath.
This is one of the earliest symptom that comes to notice. Running out of breath often is a common sign that you might be affected by lung cancer.
2. A chronic cough.
If you are having a cough that just won’t quit, pay attention to that. A cough associated with a cold or respiratory infection will go away in a week or two, but a persistent cough that lingers can be a symptom of lung cancer.
3. Chest pain.
Pain in the chest area is the most common sign that you might be affected by lung cancer. Do not overlook your chest pain, be it of any kind.
