Farmers' pesticide use linked to blood cancer precursors
NCT ID NCT01139476
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 5 times
Summary
This study looked at nearly 1,900 male farmers over age 50 to see if pesticide exposure is linked to early signs of blood cancers like multiple myeloma. Researchers collected blood and urine samples and compared those with and without exposure to the pesticide diazinon. No treatment was given; the goal was to gather information for future prevention research.
