‘It’s clear we need to change’: Report identifies four environmental factors raising cancer risk in Iowa
“Cancer is not an abstract problem in Iowa,” oncologist Richard Deming told the people gathered in the Harkin Institute’s auditorium. “It’s not rare, it’s not declining and it’s not evenly distributed.

Factory farms in Iowa generate 110 billion pounds of manure per year. No one tracks where it’s going.
More than a thousand hogs grow fat in the enclosed shed-like structures on Gene Tinker’s farm in northeast Iowa, while a few hundred cattle pace in open feedlots.

Report: Iowa’s rate of new lung cancer cases ‘significantly higher’ than national average
Iowans are used to reports on cancer rates containing bad news for the state.

No vote on bill protecting pesticide manufacturers from cancer lawsuits as Iowa House Republicans balk
The Iowa House will not vote on a bill passed by the Senate that would have provided new protections against lawsuits for corporations that produce pesticides, Speaker Pat Grassley said on Thursday. Even though Republicans control 67 of the 100 seats in the House, there was not enough support for the bill to guarantee passage. […]

Iowans gathered in the State Capitol rotunda on Monday to remember family members who have died from cancer and protest a bill in the Iowa Senate that would create new protections against lawsuits for companies that produce pesticides. “What our legislators should be doing is working on bills that lower the risk for Iowans rather than […]
