Women diagnosed with breast cancer who previously breastfed their babies had a 30 percent overall decreased risk of the disease recurring, according to a new study.

Breast feeding for six months or more was associated with even greater protection from tumour recurrence. In addition to the reduced risk of recurrence, the researchers found a 28 percent reduced risk of dying from the disease among women who breast-fed.
