Hormone Therapy & Breast Cancer Incidence Data
This 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 included in the Breast Cancer Surveillance Consortium from January 1997 to December 2003. Results of an analysis of breast cancer incidence were published by Kerlikowske et al. in the September 2007 issue of the Journal of the National Cancer Institute. This dataset includes screening mammograms performed on women aged 50-69 who did not have a previous diagnosis of breast cancer and had undergone previous breast mammography in the prior 9 to 30 months. These mammograms were linked to cancer registry and pathology data to obtain incident breast cancers (invasive or ductal carcinoma in situ) within one year following the screening mammogram. This aggregate dataset includes frequencies and adjusted quarterly rates of postmenopausal hormone therapy (HT) use and breast cancer (overall and by invasive/DCIS and ER status). All rates were adjusted by age, mammography registry, and time since previous mammogram. Other investigators may wish to explore alternative methods of analyzing the data and evaluating trends. Invasive cancers were categorized by ER status as either positive, negative, or unknown/not done.
