The Cancer Data Registry of Idaho (CDRI) is a population based cancer registry that collects incidence and survival data on all cancer patients who reside in the state of Idaho or who are diagnosed and/or treated for cancer in the state of Idaho. Population-based cancer registries are essential for assessing the extent of cancer burden in a specific geographic area.

The Idaho Hospital Association (IHA) contracts with the Idaho Department of Health and Welfare, Division of Health, to provide a statewide cancer surveillance system.
