A large, prospective cohort study conducted among agricultural workers,
farmers and their families in Iowa and North Carolina in the United States
reports that there are no associations between glyphosate use and overall
cancer risk or with total lymphohematopoietic cancers, including non-Hodgkin
lymphoma (NHL) and multiple myeloma.
The long term study updated the previous evaluation of glyphosate with
cancer incidence, and is part of the Agricultural Health Study (AHS), a
large and important project that tracks the health of agricultural workers
and their families. Led by AHS principal investigator Laura Beane Freeman,
the study results state that among 54,251 applicators studied, 44,932
(82.8%) used glyphosate. "Glyphosate was not statistically significantly
associated with cancer at any site," the study said.
