Doctors Mobile Phone Radiation Cause Malignant Tumors?

Lead mobile phones to the formation of tumors?

In recent years, there has been a lot of talk about cell phone radiation and the associated health hazard. Researchers now found that high exposure to radiofrequency radiation appears to be related to the activity of tumors.

Scientists from the National Toxicology Program found in their study that high exposure to radiofrequency radiation in male rats leads to tumors in tissues around the nerves in the hearts of rodents. Thus, the discussion about possible cancer risks of mobile phone radiation has rekindled.

In male rats, tumors were formed by the radiation

Radiofrequency (RFR) radiation resulted in the formation of tumors in male rats, but not in female rats or mice. Exposure levels used in the studies were equal to or higher than the highest level allowed for local tissue exposure to cell phone emissions. However, mobile phones typically emit lower RFRs than the maximum allowable, the experts explain.

Effects of radiation

The incidence of heart tumors, termed malignant schwannomas, increased in male rats when exposed to RFR levels in excess of allowable cell phone emissions, the researchers report. In addition, an unusual pattern of cardiomyopathy or cardiac tissue damage occurred in exposed male and female rats, the researchers say.

Radiation also affected other organs

The authors point out the statistically significant increase in the number of rats and mice with tumors found in other organs at one or more of the exposure levels studied. These organs included, for example, the brain, prostate gland, pituitary gland, adrenals, liver, and pancreas. However, the researchers found that these results were ambiguous. It was unclear whether the increase in the number of tumors was related to radiofrequency radiation, the researchers add.

Results should not be transferred directly to humans

The extent and duration of exposure to RFR in the study was much greater than the exposure to humans from cell phone use. "So these results should not be extrapolated directly to human cell phone use," explains Dr. John Bucher in a press release on the investigation results. However, it should be noted that the tumors found in previous studies are similar to those of intensive mobile phone users, adds the expert.

For the experiment, the rodents were irradiated for two years

To conduct the study, researchers built special chambers in which rats and mice were exposed to different RFR levels for up to two years. The concentration of exposure was between 1.5 and 6 watts per kilogram (W / kg) in rats and between 2.5 and 10 watts per kilogram in mice. The low energy level in the rat tests was the highest level of exposure allowed for mobile phone emissions today.

Which radiation frequency was used?

The animals were exposed for ten minutes at intervals of ten minutes, which corresponds to a total of slightly more than nine hours a day, report the doctors. The researchers used 2G and 3G frequencies and modulations, which are still used for voice calls and SMS in the United States. 4G, 4G-LTE and 5G networks for streaming video and downloading attachments use mobile phone signal frequencies and modulations other than NTP, the researchers explain.

Further effects of irradiation

The NTP studies also looked for a range of other adverse health effects in rats and mice, including changes in body weight, signs of tissue damage from RFR-generated warming and genetic damage. The researchers noted a lower body weight in newborn rats and their mothers, especially when exposed to high levels of RFR during pregnancy and breastfeeding. However, it should be noted that these animals grew to a normal size.

Results may support studies on the safety of cell phones

"These studies were complex and technically demanding, but they provide the most comprehensive assessment yet of the health effects of RFR exposure in rats and mice," says Dr. Books. Mobile phone technologies are constantly changing. The findings of the investigation provide valuable information to support future studies on the safety of mobile phones, the expert said.

FDA demanded investigation of the radiation of mobile phones

The US Food and Drug Administration (FDA) has nominated high frequency radiation from mobile phones for widespread use of mobile phones. The FDA and the Federal Communications Commission are jointly responsible for the regulation of wireless communications equipment in the United States. (As)
