Women with a family history of breast cancer and who have ever
breastfed reduce their risk of premenopausal breast cancer by nearly
60%, a study has found. Some studies have suggested that breastfeeding
reduces breast cancer risk, but evidence has been mixed. To assess the
relationship between breastfeeding intensity and incidence of
premenopausal breast cancer, researchers collected detailed information
on lactation history, supplemental feeding and lactation amenorrhea
among 60 075 participants in the Nurses' Health Study II from 1997
to 2005 who had given birth. Breastfeeding history was assessed in
detail on the 1997 questionnaire, and on each follow up women were asked
to report whether they had been diagnosed with breast cancer. A total of
608 cases of premenopausal breast cancer were diagnosed at an average
age of 46.2 years. Women who had a first-degree relative with breast
cancer had a lower risk of developing the disease if they had ever
breastfed than if they had never breastfed. There was no association
between breastfeeding and breast cancer among women without a family
history. These data suggest women with a family history of breast cancer
should be encouraged to breastfeed, say the authors. Stuebe A, Willett W, Xue F, Michels, K. Lactation and incidence of premenopausal breast cancer: a longitudinal study. Archives of Internal Medicine, 2009; 169(15): 1364-71. |
