Cancer Incidence and Mortality Among South Dakotans, 2017
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. 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.
