This paper reports the study of 1:1 matched case-control for eighty-three cases of primary lung squamo-carcinoma and seventy-one cases of primary lung adenocarcinoma from urban districts of Nanjing. The result of conditional analysis reveals that cooking oil fume is a common risk factor for lung squamo-carcinoma and adenocarcinoma. Its relative risk and population attributable risk (%) are 3.8138, 3.4466 and 51.56%, 60.99% respectively. Besides, smoking, family history of tumors, fuel types and keeping warm by coal stove in winter are selected as risk factors for lung squamo-carcinoma, while history of chronic bronchitis and family history of tumors are screened as risk factors for lung adenocarcinoma. Summary population attributable risk for all five factors of lung squamo-carcinoma and all three factors of lung adenocarcinoma are 99.47% and 76.65% respectively.
