A 10-year study by the U.S. government found clear evidence that cell phones cause cancer. The study was conducted by the National Toxicology Program (NTP), the U.S. expert agency on toxins, and it was the biggest study of its kind. The results were confirmed by another major study by a leading scientific body, the Ramazzini Institute.

Nevertheless, the Federal Communication Commission (FCC), which is entrusted with regulating the impact of wireless technology on health, dismissed the results of the study and refused to review its 1996 guidelines that deny adverse health effects of wireless technology. In February 2020, Children’s Health Defense filed a lawsuit against the FCC challenging the FCC’s decision not to review the guidelines. The U.S. Court of Appeals for the District of Columbia Circuit will hear oral arguments in the case on Jan. 25, 2021.
