Several risk factors can make you more likely to develop lung cancer. smoking is by far the leading risk factor for lung cancer. about 80 percent of lung cancer deaths are thought to result from smoking. the risk for lung cancer among smokers is many times higher than among nonsmokers. the longer you smoke and the more packs a day you smoke, the greater your risk. cigar smoking and pipe smoking are almost as likely to cause lung cancer as cigarette smoking. smoking low-tar or “light” cigarettes increases lung cancer risk as much as regular cigarettes. smoking menthol cigarettes might increase the risk even more since the menthol allows smokers to inhale more deeply. if you don’t smoke, breathing in the smoke of others (called secondhand smoke or environmental tobacco smoke) can increase your risk of developing lung cancer. secondhand smoke is thought to cause more than 7,000 deaths from lung cancer each year.
