Lung cancer affects millions of people every year. It’s not just smokers who get affected, lung cancer can occur due to a variety of reasons including air pollution, passive smoking and other indeterminate factors which are beyond normal control. As with most cancer types, even lung cancer shows early warning signs which should not be ignored. If diagnosed early, lung cancer can be treated with the right medical treatments which greatly increase the chances of survival.
1A persistent Cough
A nagging or a persistent cough without any known reasons could be a sign of lung cancer. A cough could be because of the inefficient functioning of the cells in the lung as a result of cells getting damaged. If you are having a persistent cough that does not seem to go away with cough medication, maybe you should get a cancer screening done.
