Counties with the highest cancer rates in Iowa

Several factors contribute to cancer rates, from personal habits and genetics to air pollution or groundwater quality in a given area. People experiencing social, economic, or environmental disadvantages are disproportionately affected by high cancer rates in certain regions—including access or barriers to early screening and care.

Cancer rates also fluctuate by jobs: Higher rates of cancer can be found among meat industry and rubber manufacturing workers, and farmers.
