On April 15, 2022, the NCI’s Surveillance Research Program (SRP) released the latest Surveillance, Epidemiology, and End Results (SEER) data based on November 2021 data submissions. The new data can be accessed on the SEER website by filling out a request form. Note: Institutional users may request access to the “Research Plus” databases, while non-institutional users (those without eRA Commons/NIH or HSS accounts) cannot request access to the Research Plus data without first being granted access to the “Research” data.

The research data includes SEER incidence and population data associated by age, sex, race, year of diagnosis, and geographic areas gathered from population-based cancer registries covering approximately 47.9% of the U.S. population. The new data allows researchers to study both recent and long-term trends from 1975 up to 2019, and SEER’s online tools allow the data to be filtered by age, race, sex.

SEER releases new research data every spring based on data submission in the fall. The program has been gathering data and serving as a resource for statistics on cancer in the U.S. since the early 1970s by tracking and reporting trends in incidence, mortality, survival, and prevalence. The SEER program is supported by SRP, which is part of NCI’s Division of Cancer Control and Population Sciences.
