We've known for a long time that breastfeeding had a protective effect for moms but now we have some information about WHY!
"The researchers discovered that women who had breastfed had significantly higher levels of specialized immune cells known as CD8+ T cells. These cells patrol breast tissue like guards, ready to recognize and attack abnormal cells that could turn malignant. Some of these cells were found to persist in breast tissue for up to 50 years."
A new study in Nature Communications finds that breastfeeding may activate long-lasting immune “guards” in breast tissue, helping explain its link to lower breast cancer risk.
