[Risk factors for breast cancer in Belgrade].
Reproductive history, contraceptive use, family history of breast cancer, health behaviour and socioeconomic variables of 60 women with breast cancer were compared to those of 71 age and place of living matched hospital controls. Besides nulliparity, all known risk factors for breast cancer were more frequently present in the cases observed, although the statistical significance was not attained (age at first delivery, early menarche, positive family history of breast cancer, positive history of benign breast disease, obesity). Oral contraceptives ever used were reported for 16.7% of cases and 15.5% of controls (RR = 1.09; 95% confidence interval 0.42-2.77). Although the study is small and the difference in the risk factor distribution insignificant, it is clearly consistent with many published studies on the same subject.
