There is now a clearer evidence of the link between cancer and radiation from mobile phones, according to National Health Institutes, said Thursday in the United States.
"The National Toxicology Program concluded that there is clear evidence that male rats exposed to high levels of radio frequency (RFR) use on 2G and 3G mobile phones they developed a cancerous heart tumorThe agency said in a statement. The conclusion follows from a study that assesses the impact of radio frequency exposure on mobile phones.
"There was also some evidence of brain tumors and adrenal glands in male rats. Evidence for female and female mice and mice was unclear whether the tumors observed were related to the effect of RFR. "

The report agrees with the project, which was published in February this year.
However, it was amazing Another federal health agency, FDA, disagrees with this conclusion.
"After reviewing the study, we do not agree with the conclusion of the final report on clear evidence of" quantitative effects "in rodents exposed to radio frequency energy," said Jeffrey Shuren, Director of Devices and Radiological Health at the FDA, in a statement on Thursday in response to a report.
However, both agencies dependent on the US Department of Health and Human Rights You agree that the results of these studies in rats and mice should not be used for the use of mobile phones by humans.
"The effects of research can not be directly compared to the exposure people experience when they use a mobile phone," said John Bucher, a senior scientist with the US National Toxicology Program. "In our studies, rats and humans received radio frequencies in all their bodies. Most people, for their part, are exposed to local tissues where they have a phone. In addition, in our studies, the exposure and duration was higher than that of humans. "

Final report and consensus on the National Toxicology Program they are the result of 10-year, $ 30 million research.
The study included two large animal studies – one in rats and one in mice – that linked high levels of cell phone radiation with some evidence of carcinogenicity in male rats, including an abnormal tumor that is called schwannoma in the heart. There were no significant findings in rats in females.
Similarly, no significant results were found in the mouse study.
"One of the things we found most interesting about our discoveries was that malignant schwannomas, although they happened in the heart, not at the end of the animals they were actually schwannomas"Bucher said in February when they released the draft report.
The FDA emphasizes that mobile phones emit low-frequency energy that is non-inhaling and therefore is not considered strong enough to cause prolonged damage to the biological tissues, including DNA.
National health institutes also emphasize that 5G networks or wifi studies were not included.
"5G is a new technology that has not yet been defined. "What we now understand seems to be completely different from what we have been researching," said Michael Wyde, a leading toxicologist in the research.

Confusion and contradictions
Studies on the National Toxicology Program about 3000 rodents were involved, as detailed in the draft report in February.
Animals were exposed to radiofrequency levels that are equal to or higher than the current level of mobile phone emissions. The researchers tracked animal health from the uterus for up to two years.
A 2-year-old rat may in some way be comparable to a 70-year-old mansaid Butcher.
The researchers divided the rodents into two groups based on lower or higher radiofrequency radiation levels, and all their bodies were exposed to radiation, increasing by 10 minutes at a time to reach around nine hours a day over time. two years
"It is important to consider the extent of the exposure of animals in these studies in relation to what could normally be obtained through the use of a mobile phone," said Bucher. "The lowest level of radio frequency energy that we studied was similar to the highest current level of cellular emissions"
Among male rats, researchers found that tumors were approximately 6% of those who were in the highest exposure groupsaid Bucher. This percentage "exceeded the median historical frequency (0.8%) and exceeded the highest rate observed for one historical control group (2%) of the studies performed by peers," writes researchers.
The researchers also found it Group men with the highest exposure appear to live longer than other rats, but more research is needed to determine why and how it may be related to the results of research.
"Such animal studies contribute to our discussion of this topic, but we must remember that The study was not intended to test the safety of people's mobile phones, so we can not draw conclusions about the risk of mobile phones when they are used, "said Shuren.
"Based on our current assessment on this subject, all available scientific data is still not justified by the adverse effects on human health caused by exposure below the current energy exposure limit. Radio Frequency We believe that the current limitations of mobile phone security are still acceptable in order to protect public health. "
