Diet Linked to Lower Risk of Death from Breast Cancer

Key clinical point: Women who followed a balanced, low-fat diet had a lower risk of death from breast cancer compared with women who followed their normal diet.

Major finding: The risk of death from breast cancer was significantly lower in the study-diet group than in the normal-diet group (hazard ratio, 0.79, 95% confidence interval, 0.64-0.97; P = .025).

Study details: A cohort from the Women’s Health Initiative, which randomized 48,835 postmenopausal women to a low-fat diet or to their normal diet.

Disclosures: The National Institutes of Health funded the study. The researchers disclosed relationships with Novartis, Pfizer, Amgen, AstraZeneca, Immunomedics, Metastat, Bayer, and Genentech/Roche.
