ABSTRACT
Passive smoking is an important risk factor for lung cancer and its impact might be more significant than generally appreciated in Korea. We reviewed the literatures that support the biologic plausibility of Environmental Tobacco Smoke (ETS) causing lung cancer and summarized epidemiological evidences. Because ETS exposure is a preventable risk factor, more social efforts should be directed to reduce ETS exposure.
