| English abstract | The reasons for the recently observed increase in the incidence of breast cancer in the Indian population are not clearly understood, but thought to be largely explained by westernization of lifestyles and changes in reproductive behavior, which characterize exposure to hormones. Our aim is to review the reproductive risk factors and comorbidities and evaluate the association between molecular subtypes of breast cancer. A hospital-based analytical case-control study was conducted among the breast cancer cases with controls in a multispecialty teaching hospital for a period of one year. Totally, 130 subjects were recruited and an interview was conducted using a structured questionnaire to obtain demographic and risk factor data, including tissue marker status (ER, PR and HER-2) obtained from case files. Data were analyzed with SPSS-20 version. Results: The highest age group reported in this study was 51- 60 years which has a 3.8 times increased risk compared to other age and the age group of 31- 40 have a decrease risk of 0.33. In this study, the percentage of post menopause (68%) and mothers not breastfeeding (10%) was higher in cases compared to controls and a noted increase in the risk of breast cancer with odds ratio (OR) of 2.745 (p= <0.0001) and 9.08 (p=0.01) respectively. Duration of breastfeeding showed significantly (p=<0.0001)) moderate positive correlation (r=0.549, 0.457, 0.418 and 0.636) for luminal A, luminal B, HER+, and triple negative respectively. This study found that all the reproductive risk factors do not have correlation with a molecular subtype of breast cancer except breastfeeding. Post menopause and breastfeeding were common factors associated with all people and could be modifiable to prevent the occurrence of breast cancer through lifestyle changes |
