To the Editor: Dr Schairer and colleagues1 reported an RR for breast cancer of 1.4 for women
who had used estrogen-progestin replacement therapy for 4 years compared with
women who had never used estrogen or progestin therapy. This equates to a
40% increase in the risk of breast cancer, a figure that was seized on and
widely reported by the media.
