Influence of Estrogen Plus Progestin on Breast Cancer and Mammography in Healthy Postmenopausal Women: The Women's Health Initiative Randomized Trial
Rowan T. Chlebowski,Susan L. Hendrix,Robert Langer,Marcia L. Stefanick,Margery Gass,Dorothy S. Lane,Rebecca J. Rodabough,Mary Ann Gilligan,Michele G. Cyr,Cynthia A. Thomson,Janardan D. Khandekar,Helen Petrovitch,Anne McTiernan +12 more
TL;DR: Relatively short-term combined estrogen plus progestin use increases incident breast cancers, which are diagnosed at a more advanced stage compared with placebo use, and also substantially increases the percentage of women with abnormal mammograms, a pattern which continued for the study duration.

TL;DR: Most risks and benefits dissipated postintervention, although some elevation in breast cancer risk persisted during cumulative follow-up and the 2 WHI hormone therapy trials do not support use of this therapy.

TL;DR: Among postmenopausal women, a low-fat dietary pattern did not result in a statistically significant reduction in invasive breast cancer risk over an 8.1-year average follow-up period, and the nonsignificant trends observed indicate that longer, planned, nonintervention follow- up may yield a more definitive comparison.

TL;DR: A lifestyle intervention reducing dietary fat intake, with modest influence on body weight, may improve relapse-free survival of breast cancer patients receiving conventional cancer management.
