Breastfeeding baby may delay breast cancer
Breastfeeding for more than six months and not smoking show up as very powerful protectors, pushing breast cancer diagnosis out by 10 years.
“Breastfeeding for periods of over 6 months not only provides children with numerous health benefits, but also protects the mother from serious diseases such as breast cancer. Accordingly, breastfeeding is a potential ally in the fight against breast tumors. The incidence of this disease could be reduced from 6.3% to 2.7% if women breastfed their children for more than 6 months”
Spanish University Researchers, Journal of Clinical Nursing, August 2013.
In this retrospective study, women who breastfed their children for more than six months and who did not smoke, delayed the onset of breast cancer by 10 years.
- Breastfeeding alone was protective but it did not overcome the damaging and breast cancer-causing effects of smoking.
- Smokers got breast cancer younger overall, with an age at diagnosis about 9 years less than for the nonsmokers.
- The average age of breast cancer diagnosis was 56.7 among the women who either hadn’t had children or who had breastfed for less than 3 months.
- The average age of breast cancer diagnosis was 65.4 among the non-smoking women who had breastfed for more than 6 months.
- The findings stood up regardless of any family history of breast cancer.

The researchers retrospectively analyzed medical records of 504 women in the province of Granada, Spain, diagnosed with breast cancer at ages 19 to 91 years at a single center from 2004 to 2009. The study was supported by the San Cecilio University Hospital of Granada. As reported by MedPage Today on August 16, 2013.
