Andrews University, Buller Hall

We modeled breast cancer in a Cox proportional hazard regression analysis and found 25% lower risk for those who initiated breastfeeding than those who never breastfed. There was a threshold effect for duration of breastfeeding and increased risk for family history of breast cancer, recent HRT use, and higher education.
