Objective: This study aimed to evaluate the possible association between air pollution and breast cancer in women living in polluted urban areaMethods: A frequency (five years age group) matching case-control study was conducted among women living Tehran Metropolis. Ambient carbon dioxide (CO2) as an indicator of exposure to air pollution and particulate matter 10 (PM10) as a carcinogen were used as exposure. Concentrations of the two indicators for the residential address of cases and control for the last five years were obtained from office of Tehran Air Quality Control Bureau (TAQB). All subjects were interviewed by phone and information about other risk factors (hormonal, behavioral anthropometric, and socio-economics) were obtained. Multivariate logistic regression model was used to estimate the odds ratios adjusted for confounding variables. CO2 entered into in the model as a continuous variable and PM10 was categorized as PM10 ≤ 1 VS 1 2 µg/m3 = 97) for cases and (PM10 2 µg/m3 = 105) for controls. Also CO2 index was a significant different with control groups as mean was (3943.87±3.50 µg/m3) for controls and (3199.84±2.72 µg/m3) for cases (P-value= 0.03). logCO2 as general indicator of exposure to air pollution was not observed association with breast cancer (OR = 1.218 and CI 95% 1.000 to 1.000). subjects in the case and control groups had no signific nt difference in terms of the level of PM10 index (OR = 1.047 and CI 95% 1.005 to 7.278). Conclusion: According to the results of this study, risk of breast cancer increases in women with exposure to air pollution, which denotes air pollution as a potential risk factor of breast cancer.
