1998-2002 Breast Cancer Incidence Map and Table. This color-coded map and table of New York State breast cancer incidence rates by county was created using data from the New York State Department of Health's Cancer Registry. Maps show age-adjusted rates of breast cancer (the number of people who develop breast cancer per 100,000 individuals). Maps and cancer rate statistics can be valuable tools for spotting trends or anomalies across classifications such as geography or time.
