A 10-year long US-based research study has concluded that Radio Frequency Radiation (RFR) emitted by the cellphones can cause cancer in rats and mice.
However, the report found that these results cannot apply to human beings, as they experience way lower radio wave doses than the mice and rats were exposed to.
The research found evidence that the RFR can cause brain and heart tumors in male rats. However, the signs of cancer because of radiation remained unclear in female rodents and male mice.
The results of the research indicate that high exposure to RFR can cause cancer in a few animals; however, given that the human beings get exposed to much lesser radiations, the results cannot be applied to them.
It is pertinent to mention here that the US government commissioned this study to the National Toxicology Program (NTP) more than a decade ago. It cost $30 million to undertake.
The report concludes that high levels of RFR can cause heart tumors in male rats. There is some evidence that RFR causes brain tumors and cancer in adrenal glands. However, the report could not find any clear evidence whether RFR can cause any tumor in female rats or mice in general.
Overall, the report neither denies nor supports whether RFRs can cause cancer in human beings.
