Overview
This hormone therapy and breast cancer incidence dataset may be useful to people interested in exploring the relationship between postmenopausal hormone therapy and breast cancer incidence. The dataset includes information from 603,411 screening mammograms performed on women in the Breast Cancer Surveillance Consortium from January 1997 to December 2003. Results of an analysis of these data were published by Kerlikowske et al. in the September 2007 issue of the Journal of the National Cancer Institute. This dataset includes screening mammograms in women aged 50-69 who did not have a previous diagnosis of breast cancer and who had undergone breast mammography in the prior 9 to 30 months. The mammogram data were linked to cancer registry and pathology data to identify incident breast cancer (invasive or ductal carcinoma in situ) within one year after the screening mammogram. This aggregate dataset includes frequencies and adjusted quarterly rates of postmenopausal hormone therapy use and breast cancer (overall and by invasive/DCIS and estrogen receptor status). All rates were adjusted for age, BCSC mammography registry, and time since the previous mammogram. Investigators may wish to explore alternative methods of analyzing the data and evaluating trends. Invasive cancers were categorized by estrogen receptor status as positive, negative, or unknown/not done.
