This is a reality for hundreds of thousands of smokers in the United States alone. Still smoking when they know that something is wrong with their lungs or at least the signs and symptoms are there. The symptoms of lung cancer can be shortness of breath to chronic coughing and wheezing, which are known results of smoking, but does this mean you have lung cancer? Do you still smoke cigarettes even though you are having such difficulty breathing?
The only real way to be able to tell if you are a victim of lung cancer is to have a chest x-ray done on your lungs.
