Abstract

Breast cancer (BC) is a global public health problem attributed to varying risk factors. The designing of a targeted screening program focused on at-risk women can be cost-effective in reducing its burden. A hospital based case control study was conducted on 138 cases of breast cancer and 169 healthy controls to investigate the reproductive and non-reproductive risk factors for breast cancer in Pakistani women. The odds ratios (ORs) and 95% confidence intervals (CIs) were computed with unconditional logistic regression. Almost all i.e. 97.83% of cases were married (OR=5.03),70.29% were illiterate (OR=1.88), 73.19% were aged >35 years (OR=0.632) and 81.16% belonged to the poor class(OR=1.81). Early age at menarche (OR, 2.55; 95% CI 1.50-4.31, P=0.0001), hormone replacement therapy (OR=2.057, 95% CI 1.283-3.295, P= 0.002) early pregnancy (OR,2.23, 95% CI 1.29-3.88, P=0.004), history of miscarriage (OR, 2.11, 95% CI 1.32-3.39,P=0.002) & oral contraceptive use (OR, 2.76, 95% CI 1.54-4.92, P= 0.006) were significantly associated with BC. The study highlights the dire need for effective public health programs for high-risk women to address this highly fatal disease. (Afr J Reprod Health 2023; 27 [10]: 57-64).
