Breastfeeding's Role in Reducing Breast Cancer Risk

Originally published online at https://arbonahealthhub.com/2024/11/20/breastfeeding-as-a-protective-factor-against-breast-cancer/ This article explores the complex relationship between breastfeeding and breast cancer risk, highlighting that prolonged lactation offers significant protection against hormone receptor–negative (ER–/PR–) and triple-negative breast cancer subtypes, though it shows no clear benefit for hormone receptor–positive cases. Studies indicate that breastfeeding for over six to twelve months reduces cancer incidence by 4–82%, with additional protective effects from parity, physical activity, and soy consumption, while factors like alcohol use and high BMI increase risk. The article also addresses challenges faced by breast cancer survivors who wish to breastfeed, such as reduced milk production and psychological barriers, and emphasizes the importance of multidisciplinary support to safely continue lactation and maintain its protective benefits. Finally, it calls for more research on post-treatment breastfeeding experiences to improve survivorship care and preventive strategies.
