Cancer Burden in South Dakota

The SD Department of Health has two excellent tools available online to find specific cancer information in South Dakota. For information on the cancer burden within a specific county, the South Dakota Cancer Incidence & Mortality tool provided by the SD Cancer Registry allows for quick cancer data comparisons by county. In addition, the Data Query System provides users with a searchable database to gather statistics related to births, deaths, abortion and cancer events. See image below for an example of what is created by the SD Cancer Incidence & Mortality tool.

Cancer Incidence and Mortality Among South Dakotans, 2015

This report summarizes the burden of cancer in South Dakota and includes cancer incidence and mortality data. The data will enable the many organizations working with cancer prevention and control to identify public health problems, target goals for cancer control, and to inform citizens and health care professionals about risks, early detection, and treatment.
