Major WHO-backed study: high certainty that wireless radiation causes cancer in animals

A new systematic review of animal studies on wireless radiofrequency (RF) radiation and cancer commissioned by the World Health Organization (WHO) and published in Environment International concluded with “high certainty” that exposure to wireless RF radiation causes two types of cancer in animals. The “certainty” reflects how confident researchers are that the observed effects — such as the link between wireless RF radiation and cancer — are real and not due to chance, bias, or flaws in the study design.

Animal studies do not always directly translate to human health risks, but if animal studies show evidence of a substance causing cancer, the World Health Organization’s International Agency for Research on Cancer (IARC) and the U.S. Agency for Toxic Substances and Disease Registry (ATSDR) generally consider it a potential human carcinogen.
