Cause of Lung Cancer
There are several different lung cancer causes -- tobacco use is certainly the most common; pollution, lung disease, and exposure to asbestos or radon are also contributing factors. Sometimes, knowing the cause of this disease can help you avoid activities that may increase your risk. For example, if you smoke, quit -- better yet, don't start in the first place. However, researchers continue to explore this topic in order to better understand, treat, and possibly prevent lung cancer.
