The Big Picture. Lung cancer is the top cause of cancer deaths in both men and women. But this wasn’t always the case. Prior to the widespread use of mechanical cigarette rollers, lung cancer was rare. Today, smoking causes nearly 9 out of 10 lung cancer deaths, while radon gas, pollution, and other things play a smaller role.
