Body fat levels linked to breast cancer risk in post-menopausal women
(CNN) -- Older women with excess body fat, even if they have what's considered a normal body-mass index, could be at greater risk for breast cancer, according to a study published Thursday in the medical journal JAMA Oncology. "We do find that excess body fat in those who are post-menopausal with a normal body mass index is associated with about a doubling in the risk of estrogen-dependent breast cancer," said Dr. Andrew Dannenberg, one of the study's authors and director of cancer prevention at the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine.
