Exposure to benzene through parental occupation and the use of household products has been associated with childhood leukemia (CL). Ambient benzene has also been associated with CL and central nervous system (CNS) tumors. We aimed to investigate whether the higher ambient levels of benzene in proximity of petrol stations are associated with a greater risk of childhood cancers, leukemia, and CNS tumors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      We identified children diagnosed with cancer at age 0\u201315\u00a0years during 1985\u20132015 from the Swiss Childhood Cancer Registry and selected 10 age and sex-matched controls per case from national censuses. We calculated the distance from children\u2019s home to the nearest petrol station using precise geocodes.

The adjusted odds ratio of a cancer diagnosis for children thus exposed compared to unexposed children (&gt;\u2009500\u00a0m) was 1.29 (0.84\u20131.98) for all cancers combined, 1.08 (0.46\u20132.51) for leukemia, and 1.30 (0.51\u20133.35) for CNS tumors. During 2000\u20132015, when exposure assessment was more precise, the adjusted odds ratio for any cancer diagnosis was 1.77 (1.05\u20132.98).
