History of breast feeding and risk of incident endometriosis: prospective cohort study. Farland et al – BMJ, 2017
Conclusion Among women who experienced at least one pregnancy that lasted at least six months, breastfeeding was inversely associated with risk of incident endometriosis. This association was partially, but not fully, influenced by postpartum amenorrhea, suggesting that breastfeeding could influence the risk of endometriosis both through amenorrhea and other mechanisms. Given the chronic and incurable nature of endometriosis, breastfeeding should be further investigated as an important modifiable behavior to mitigate risk for pregnant women
