SEER collects data on cancer cases from various locations and sources throughout the United States. Data collection began in 1973 with a limited number of registries and continues to expand to include even more areas and demographics today.
Managers/PIs: Save the date for our annual SEER meeting on October 3-5, 2023.
The National Cancer Act (NCA) of 1971 expanded the authorities of the National Cancer Institute (NCI) and its director, including the mandate to establish the National Cancer Program. As a direct result of the NCA, the National Cancer Program required the creation of a data bank for the collection, storage, analysis, and dissemination of cancer data to support research on prevention, diagnosis, and treatment.
This marked the birth of the Surveillance, Epidemiology, and End Results (SEER) Program, the main program that the NCI uses to support cancer surveillance activities that enable monitoring trends in cancer diagnosis and outcomes. Case ascertainment and data collection for the SEER Program began with January 1, 1973, diagnoses in several geographic areas of the United States and its territories. Geographic area and demographic coverage have expanded over the past 50 years, to represent nearly 50% of the U.S. population today.

50 years of SEER Tools
SEER has developed a variety of statistical tools and methods for analyzing cancer data. These resources that are available to the research community have contributed to our understanding of nation-wide trends in cancer incidence and survival.
Quotes on the Value of SEER
We're celebrating the 50th anniversary of the Surveillance, Epidemiology, and End Results Program, or SEER. SEER is an indispensable tool in the fight against cancer. It covers almost half of the U.S. population through participating cancer registries, and analysis of SEER data each year provides us with our report card, telling us where we stand with various cancers by powering important reports like the Cancer Trends Progress Report and the Annual Report to the Nation on the Status of Cancer. We can expand and further empower SEER to go broader, cover even more, and help us really address the needs of our underrepresented populations. This is a goal to which we aspire.
Dr. Monica M. Bertagnolli
Director, National Cancer Institute
The people and the data available through the SEER Program are incredibly helpful for cancer researchers. I spent three years as a postdoctoral fellow at SEER, and I continue to benefit from the training I received, particularly in accessing and analyzing cancer surveillance data. The tools available through SRP, including SEER*Stat, HD*Calc, and Joinpoint, have allowed me to conduct novel analyses of disparities in cancer outcomes to motivate peer-reviewed manuscripts and grant proposals. Overall, the SEER Program is foundational for research on cancer outcomes, and is a great resource for early-career scientists!

From its inception in the early 1970s, SEER has been ahead of the curve. They have prioritized data quality control and built a reputation as a trusted data source.

Population Coverage Change in 50 Years
SEER began collecting data on cancer cases on January 1, 1973, in the states of Connecticut, Iowa, New Mexico, Utah, and Hawaii and the metropolitan areas of Detroit and San Francisco-Oakland. Since then, the SEER Program has been expanded to cover numerous additional areas. See About the SEER Registries and the List of Registries for detailed information on the SEER Registry coverage.
