Does cigarette smoking cause lung cancer?

ANSWER

It can. About 90% of lung cancers result from tobacco use. Your odds are higher the more you smoke. Among those who smoke two or more packs of cigarettes per day, one in seven will die of lung cancer. There is no safe level of exposure to tobacco smoke.
