22 pesticides show links to prostate cancer

Nearly two dozen pesticides are associated with an increased risk of prostate cancer in the United States, researchers report November 4 in Cancer. Four of those, the study finds, are also linked to prostate cancer deaths.

The findings can’t say for certain that these pesticides caused prostate cancer, says John Leppert, a urologist at Stanford University School of Medicine. It’s unknown whether the people who were diagnosed with prostate cancer in Leppert’s data were exposed to the pesticides.
