Iowa cancer burden emerges as key issue in governor race

Driving the news: Lahn will sit down with cancer survivors and advocates Tuesday for an American Cancer Society Cancer Action Network (ACS CAN) "Cancer Coffee Chat" at the Urbandale Public Library.

• Lahn has made cancer and water quality prominent campaign issues, arguing that nitrate pollution contributes to Iowa's cancer burden and supporting incentives for cleaner farming practices.
• He also calls for increased exercise in schools and reducing processed foods and food dyes.

The other side: Sand joined ACS CAN's cancer roundtable three weeks ago and completed its questionnaire, backing Medicaid expansion and lower screening costs.

• He also supports additional pediatric cancer research, radon testing, and higher tobacco taxes, but stops short of endorsing ACS CAN’s full $1.50-per-pack tax increase.

Context: Both candidates say the issue is personal. Lahn discussed his father's non-Hodgkin's lymphoma in March, noting his lifetime of working in farm fields.

Between the lines: Medicaid presents one of the clearest policy contrasts.

• Sand favors unwinding Medicaid privatization, in which for-profit companies administer the system rather than the state government — a model critics say leads to unfair denials.

• Lahn favors private insurers continuing to administer Medicaid but with tighter oversight.

Zoom in: The candidates have also taken notably different approaches to vaccines more broadly, though they have not yet answered the same question.

• Sand wants to protect access to the HPV vaccine.
• Lahn, who hasn't yet answered ACS CAN's questionnaire, previously called for a ban on mRNA vaccines, including those used for COVID-19.

What we're watching: How Tuesday's event could sharpen the candidates' contrasts on cancer.

• The venue has limited space and is reserved for cancer survivors, ACS CAN volunteers, and media who have secured spots.
