Data Query Tools


SEER*Explorer is an interactive website to provide easy access to a wide range of SEER cancer statistics. It provides detailed statistics for a cancer site by gender, race, calendar year, age, and for a selected number of cancer sites, by stage and histology.


NCCR*Explorer provides incidence and survival statistics for cancers in children, adolescents, and young adults ages 0-39, using data from the National Childhood Cancer Registry (NCCR).

Cancer Query Systems (CanQues)

CanQues applications provide access to cancer statistics stored in online databases. These systems do not perform calculations; they display reports using databases of statistics generated by other software.

State and Geographic Data

State Cancer Profiles

The State Cancer Profiles website is a comprehensive system of interactive maps and graphs enabling the investigation of cancer trends at the national, state, and county levels.

Geographic Information Systems (GIS) Portal

NCI GIS Portal is a web-based station for interactive mapping and visualization of cancer-related geo-spatial data. The portal combines Geographic Information Systems (GIS) and Science principles and tools to harmonize relatively large and multi-dimensional datasets, including population-based cancer statistics and behavioral, environmental, clinical, socioeconomic, and policy data at the county and state levels.


Age-adjusted U.S. incidence and mortality rates by geographic region, plus the confidence intervals for those rates and their ranks.

Small Area Estimates for Cancer-Related Measures

State, county, or health service area estimates for smoking prevalence, cancer screening rates, smoke-free policies, smoking cessation, and cancer-related knowledge based on national surveys.

Special Topics

Know Your Chances

Interactive risk charts to put chances of dying from cancer and other diseases in context.

Oral Cancer Survival Calculator

This tool provides survival estimates based on characteristics of a person's cancer and overall health. Cancer survival statistics often focus only on the cancer. The Oral Cancer Survival Calculator puts equal focus on the chance of dying of cancer and other causes.
