Historical Landmark Studies in Surveillance

Surveillance of cancer patterns is the foundation of the SEER network. It has been the primary means of measuring the national burden of cancer through incidence, morbidity, mortality, and survival statistics, as well as evaluation of the impact of cancerrelated risk factors. Surveillance includes descriptive studies, geospatial and GIS clusters/outbreaks data, sentinel/signal/early warnings, health disparities, models and methods, and policy data.
