The mammogram data were linked to the 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).
