Breastfeeding for a longer duration (> 12 months) is associated with more protection for breast cancer than lesser (< 6months and 6-12 months) duration when compared to no breastfeeding at all (Chowdhury et al., 2015). The longer the duration of breastfeeding is, the greater is the protection. The risk gets reduced by 4% for every 12 months of breastfeeding. An inverse relationship was found between the duration of breastfeeding and the risk of breast cancer among premenopausal women.

According to various research papers, with prolonged breastfeeding, a reduction in the risk of breast cancer among premenopausal women has been reported. Younger age at first lactation was also found to be associated with reduced risk of premenopausal breast cancer. Breast-feeding also has a protective role in females with BRCA1 gene mutation who have an increased risk for the development of breast cancer. Breastfeeding for one or more years conferred a significant 32% reduction in risk in BRCA1 mutation carriers Women with BRCA mutation should be advised of the benefits of breastfeeding in reducing the risk of breast cancer.

As breastfeeding is one of the few known modifiable risk factors for breast cancer. Advocating breastfeeding and creating awareness in women will not only improve the child's health but will also reduce the risk of breast cancer on the mother. The need of the hour is various health campaigns which can educate women about breastfeeding behaviour and explain its contribution in reducing the risk of breast cancer. While breastfeeding does reduce the risk of breast cancer, it doesn't completely nullify the chances. It is important to screen your breast annually.
