Trends in cancer incidence, mortality, and patient survival in the United States, as well as many other studies, are derived from this data bank. The geographic areas comprising the SEER Program's data base represent an estimated 13.9 percent of the United States population. Breast cancer-related data are available or procured for distribution to outside researchers without restrictions related to collaboration. Must sign a data confidentiality statement.
