WATCH: What 50 years of Iowa cancer data actually shows (w/ Mary Charlton) – Cornhole Champions Interview

By Iowa Production Staff

August 1, 2025

Dr. Mary Charlton directs the Iowa Cancer Registry, tracking cancer diagnoses across the state for over 50 years and helping researchers understand Iowa’s stubbornly high cancer rates.

On this episode of Cornhole Champions, Zachary Oren Smith talks with Charlton about what the data really shows, why simple explanations for complex problems fall short, and the challenge of doing long-term science in a world that wants quick answers.

Toss some bags at complicated truths… geographic patterns that don’t fit neat theories… the politics of risk factors… why linking cancer to environmental causes takes decades… and the funding crisis threatening Iowa’s public health infrastructure.

Cornhole Champions is a weekly podcast powered by Iowa Starting Line. This podcast is produced by Zachary Oren Smith and edited by Rebecca Steinberg. Our music is by Avery Mossman and our show art is from Desirée Tapia.
