Exploring the profound link Breastfeeding's impact on alleviating the burden of breast cancer -A review

Breastfeeding has emerged as a critical factor in understanding and potentially mitigating the risk of breast cancer among women.This review delves into the intricate relationship between breastfeeding and breast cancer, elucidating the biological mechanisms, protective effects, and broader implications for public health.Epidemiological evidence consistently demonstrates a correlation between breastfeeding and a reduced risk of breast cancer, with longer durations of lactation showing a dose-dependent decrease in risk.The biological nexus between breastfeeding and breast cancer involves hormonal changes and the elimination of potentially damaged cells, influencing breast tissue and potentially mitigating carcinogenesis.Moreover, breastfeeding appears to impact tumor subtypes and aggressiveness, particularly demonstrating associations with lower risks of hormone receptornegative and certain aggressive breast cancer subtypes.Recognizing the significance of breastfeeding in reducing breast cancer risk has profound public health implications, necessitating comprehensive support, education, and policies to encourage and facilitate breastfeeding.Abbreviations: ER = estrogen receptors, HER2 = human epidermal growth factor receptor 2, PR = progesterone receptors, TNBC = triple-negative breast cancer.
