Clear evidence has emerged that cell phones causes cancer to rats, but what that means to humans remains inconclusive.
The National Toxicology Program (NTP) concluded there is clear evidence that some male rats (five to seven percent) exposed to high levels of radio frequency radiation equivalent to irradiating their bodies with second generation (2G) and third generation (3G) cell phones for nine hours daily over two years developed cancerous heart tumors, the National Institute of Environmental Health Sciences (NIH) reported.
There was also some evidence of tumors in the brains and adrenal glands of two to three percent of male rats exposed to the radiation. For female rats, and male and female mice, the evidence was equivocal.
However, John Bucher, Ph.D., a senior NTP scientist, said the exposures used in the studies “cannot be compared directly to the exposure that humans experience when using a cell phone” as the rats and mice received radiation across their whole bodies and experienced higher levels and durations of radiation than any person.
