Data collection was conducted through interview.  Association of various kinds of risk factors with breast cancer was studied using χ2, odds ratios with 95% confidence intervals through both the univariate and multivariate analysis.

Results: The findings based on univariate analysis showed that education, occupation, spouse's job, income, history of breast disease, body mass index (BMI), waist-to-hip ratio (WHR) were significantly associated with breast cancer. After entering the significant variables in the multiple logistic regression model, age at first live birth (OR = 5.04), income (OR = 3.92) and BMI (BMI> = 30) (OR = 3.84) remained significant.
