The US National Toxicology Program (NTP) reports to the National Institute of Environmental Health Sciences (NIEHS), which is one of 27 Institutes in the US National Institutes of Health (NIH).

The US National Toxicology Program (NTP) Study on Cell Phone Radiation found “clear evidence” of cancer, heart damage and DNA damage in a 14-year, $30-million study designed to test the basis for federal safety limits (NIEHS 2018). The heart and brain cancers found in the NTP study rats are the same cell type as tumors that researchers have found to be increased in humans who have used cell phones for over 10 years. Thus, researchers say this animal evidence confirms the human evidence associating the exposure to cancer. (Hardell 2019)

“The findings of highly malignant and quite rare brain tumors and malignant Schwann cell tumors of the heart in the NTP study present a major public health concern because some of these same types of tumors had been reported in epidemiological studies of adult cellphone users. In addition, the NTP reported DNA damage was induced in brain cells of exposed animals.” ~ Ronald Melnick, PhD, Commentary on the NTP Study
