New study shows association between breastfeeding and a reduced risk of aggressive breast cancer

Breastfeeding is associated with a lower risk of developing an aggressive form of breast cancer called hormone-receptor negative, a large international study shows. Hormone-receptor-negative (HRN) breast cancers are more likely to be aggressive and life-threatening. This subtype is more commonly diagnosed in women under age 50.

It’s critical to remove the barriers to breastfeeding at home, in the community and in the workplace. “All approaches will be necessary in order to protect the most women against the devastation of breast cancer over their lifetimes,” says Farhad Islami, M.D., Ph.D., director of interventions, Surveillance and Health Services Research, American Cancer Society.

“Pregnant women and young mothers are highly receptive and motivated to make healthy choices. We need to encourage women who are able to breastfeed to do so for their breast health, in addition to the health of their children,” says Paolo Boffetta, M.D., associate director for population sciences at the Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai. “Further prospective research will be necessary to further understand the full impact of breastfeeding duration and its effect on other subtypes.”
