Most probably you have heard or read about lung cancer through media or experts, you may think that you are out of this? Perhaps you are the one who does not smoke or does not belong to a polluted area. Anyhow you must be aware of these early signs that a person shows when he suffers from lung cancer.
American Cancer Society researches have shown that 80% of those suffering from lung cancer were smokers and others were non-smokers. As in those 20% non-smokers, smoking was not the cause then other factors that caused lung cancer may include environmental factors or gene mutations. Lung cancer is the most common type of cancer and the important factor of cancer deaths. Of the newly cancer suffering patients diagnosed, nearly 14% are those who are diagnosed to have lung cancer.
