People who are exposed to pesticides may face an increased risk of liver cancer, a new meta-analysis suggests. Pesticide exposure was associated with a 71 percent increased risk of liver cancer, according to the meta-analysis, which was presented on April 3 at the American Association for Cancer Research’s annual meeting in Washington, D.C. The findings have not yet been published in a peer-reviewed journal. Liver cancer is the sixth most common cancer in the world, and the No. 2 cause of cancer deaths (behind lung cancer), said lead study author Hamdi Abdi, a cancer research fellow at the National Cancer Institute.
