BCERF Brief (in English) for Teachers, Breastfeeding and Other Reproductive Factors for Breast Cancer

Abstract

Established breast cancer risk factors are factors for which there is general agreement from research studies of a relationship with breast cancer risk. Several of the established risk factors involve a woman’s exposure to the hormone estrogen made by her own body and her reproductive history. Risk factors that can be modified provide actual targets for breast cancer risk reduction. Breastfeeding decreases breast cancer risk and is a good example of an established, modifiable risk factor.
