Since ER- tumors, which have lower survival rates and are less dependent on estrogen levels than ER+ tumors, account for only 15-20 percent of breast cancers, large pooled analyses are needed to determine the suspected link to lower ER- breast cancer risk and the consumption of fruits and vegetables.
In order to determine if there is a link between the lowered risk of ER- breast cancers and the intake of fruits and vegetables, Seungyoun Jung, Sc.D., formerly from the Department of Nutrition, Harvard School of Public Health, and currently at the Channing Division of Network Medicine, Brigham and Women's Hospital, and colleagues analyzed data from 20 cohort studies of women who were followed for a maximum of 11-20 years.
The ER+ women scored significantly lower than the ER- and control groups on a sophisticated and sensitive scratch-and-sniff test.
