[en] The study by Schairer et al. aims to determine whether increases in risk of breast cancer associated with the estrogen-progestin regimen are greater than those associated with estrogen alone. This study is a cohort of follow-up data for 1980-1995 from the Breast Cancer Detection Demonstration Project, a nationwide breast cancer screening program that involved 29 screening centers throughout the United States. A total of 46,355 postmenopausal women were followed. During follow up, 2,082 cases of breast cancer were identified. Increases in risk with estrogen only and estrogen-progestin only were restricted to use within the previous 4 years. The relative risk increased by 0.01 with each year of estrogen-only use and by 0.08 with each year of estrogen-progestin-only use among recent users. Among women with a Body Mass Index of 24.4 kg/m2 or less, increases in relative risk with each year of estrogen-only use and estrogen-progestin-only use among recent users were 0.03 and 0.12, respectively. The authors conclude that the estrogen-progestin regimen increases breast cancer risk beyond that associated with estrogen alone. This study was largely commented in the lay media. Unfortunately the Belgian media introduced the confusion between the relative risk and the risk attributable to estrogen and estrogen-progestin. The aim of this manuscript is to precisely inform our colleagues, to analyze the Schairer study and to present the actual figures of risk associated with the use of estrogen and estrogen-progestin replacement therapy. Finally, we formulate some suggestions for the physician to whom the patient declares: "Did you read the negative effects of hormones?". What should we advice?
