# Surveillance, Epidemiology, and End Results (SEER)

## Overview

The Surveillance, Epidemiology, and End Results (SEER) Program provides information on cancer statistics in an effort to reduce the cancer burden among the U.S. population. SEER collects cancer incidence data from population-based cancer registries covering approximately 47.9 percent of the U.S. population. The SEER datasets include data on patient demographics, primary tumor site, tumor morphology, stage at diagnosis, and first course of treatment. [\[1\]](#references)

SEER offers the following datasets:

* **SEER Research Data**
  * Register with any valid email
  * Excludes geography, month and year of diagnosis, and other demographic fields
* **SEER Research Plus and NCCR Data**
  * Requires user authentication through eRA Commons or an HHS account.
  * Includes geography, month, and year of diagnosis, other demographic fields
  * Includes [National Childhood Cancer Registry (NCCR) data](https://nccrexplorer.ccdi.cancer.gov/data-products.html) excluding geography

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bcbi.brown.edu/codiac-for-health/ursa-ri/datasets/surveillance-epidemiology-and-end-results-seer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
