Multiple primary and authoritative sources agree that Iowa ranks second in the U.S. for cancer incidence, behind Kentucky, as of the claim date (2026-11-06). The one contrary listing comes from an unrated site with different data and does not overturn this.

This claim is about the present, so it is judged as of the day it was checked.

What was said

… There's probably articles on this, but, um, oh, it it, like, like, out of every issue in Iowa, it's the number one issue in Iowa. Like Flint, Michigan, same sort of deal. It's it's a massive issue, and Iowa has the it's the second highest cancer rates in the country, which means the world. If you look at a map of where glyphosate's used and then a map of cancer in the United States, it's almost identical. What has the first highest? Kentucky. And the same thing?

What we found

Supports. The NIH State Cancer Profiles table ranks Iowa 2nd of all states for age-adjusted all-sites cancer incidence (2018-2022), at 498.8 per 100,000, behind Kentucky at 519.0.[1]

Supports. The Iowa Department of Health and Human Services page, published 2026-11-03 before the post, states that Iowa has the second highest cancer incidence rate in the U.S.[2]

Supports. An American Cancer Society press release dated 2026-11-09 and an Iowa Public Radio report from March 2026 both describe Iowa as having the second-highest cancer rate in the country.[4][5]

Contradicts. An unrated site's 2023 new-case table lists Kentucky first and West Virginia second, with Iowa not shown in the excerpt. This uses different years and data and comes from a low-credibility source, so it does not overturn the primary records.[6]

Context. The HDPulse data show Iowa's all-sites incidence rate as rising and above the U.S. rate, which is consistent with a high national ranking.[3]
