In order to evaluate the influence of sex hormones on breast cancer risk, a population-based case-control study was conducted in Denmark, including 1,486 cases diagnosed over a one-year period. These were identified from the files of the nation-wide clinical trial of the Danish Breast Cancer Cooperative Group and the Danish Cancer Registry. The control group was an age-stratified random sample of 1,336 women from the general population. Data on risk factors were collected by self-administered… CONTINUE READING
