Representative Mark Thompson, a Republican from Clarion, Iowa, reported in his weekly newsletter that state lawmakers received an update on a $1 million state-funded study examining the main causes of cancer in Iowa. The study found that Iowa ranks second in the nation for new cancer cases among adults ages 20 to 39, but farmers were about 13% less likely to develop cancer than the general population. Thompson also highlighted a bill he authored that allows certain crimes committed by human trafficking victims to be expunged, making Iowa one of the last states to offer this protection.
Why it matters
The cancer study provides important insights into health trends and risk factors in Iowa, while the human trafficking bill addresses a critical issue of protecting vulnerable victims. Both pieces of information are relevant to Thompson's constituents and the broader state population.
The details
The cancer study, conducted by researchers at the University of Iowa College of Public Health, focused on farmers and pesticide applicators. While Iowa ranks second nationally for new cancer cases in young adults, the study found that farmers were less likely to develop cancer, likely due to lifestyle factors like lower alcohol use, more physical activity, healthier diets, and lower tobacco use. Thompson also discussed HF2696, a bill he authored that allows certain crimes committed by human trafficking victims to be expunged, making Iowa one of the last states to offer this protection.
- Last week, state lawmakers received an update on the $1 million cancer study.
- Last week, 34 bills reached the House floor for a vote, including HF2696 authored by Thompson.
