Study on Brain Cancers in Farmers

Brain cancer is nearly uniformly fatal but the etiology of this disease remains
largely unknown. Incidence and mortality rose significantly from the mid-70s
through the 80s and then declined somewhat. However, among the elderly, rates
increased most rapidly and did not then decline.

Farmers are generally at lower risk for cancer overall. However, farmers have
consistently been found to be at increased risk for brain cancer; the reason
for the observed increase is unclear.

An epidemiological study by scientists and colleagues of the National Institute
for Occupational Safety and Health (NIOSH) examining the incidence of brain
cancer in farmers was published in the June issue of the American Journal of
Epidemiology. Building on previous research, the study reported on statistical
risks for brain cancer in regard to exposures associated with certain farm
activities.
