The apparent effect of environmental tobacco smoke (ETS) exposure on cancer risk has become an important social and political issue. The risk of cancer in non-smokers is often the main reason for prohibiting or restricting smoking in public places. A number of epidemiological studies have shown an association between ETS exposure and lung cancer. However, the strength of this association has still to be estimated. Only a few studies have reported on ETS and cancer from sites other than the lung in adults. No definite conclusions can be drawn at present from a critical review of the epidemiological evidence, but the suggestion of an association is present for sinonasal cancer, while bladder cancer does not seem to be associated to ETS exposure. Positive studies are available for cancers from other sites, including the breast, the uterine cervix and the brain, but these are difficult to interpret.
接触环境烟草烟雾（ETS）对癌症风险的明显影响已成为一个重要的社会和政治问题。非吸烟者患癌症的风险通常是在公共场所禁止或限制吸烟的主要原因。多项流行病学研究表明，接触ETS与肺癌之间存在关联。然而，这种关联的强度仍有待评估。只有少数研究报告了成人肺部以外部位的ETS与癌症的关系。目前，对流行病学证据进行批判性审查后无法得出明确结论，但有迹象表明ETS与鼻窦癌有关联，而膀胱癌似乎与接触ETS无关。对于包括乳腺癌、子宫颈癌和脑癌在内的其他部位的癌症，有一些阳性研究，但这些研究难以解释。
