London, July 25,2015:  Your fears are not completely unfounded. Mobile phones can actually cause cancer, says a study.

A metabolic imbalance caused by radiation from your wireless devices could be the link to a number of health risks, such as various neuro-degenerative diseases and cancer, the study suggested.

This imbalance, also known as oxidative stress, is defined as “an imbalance between the production of Reactive Oxygen Species (ROS) and antioxidant defense” by the authors.

The hazardous effects of radiation from wireless devices could be realized through the “classical mechanisms” of oxidative impairments in living cells, the researchers said.

The study, published in the journal Electromagnetic Biology & Medicine, explored experimental data on the metabolic effects of low-intensity Radio Frequency Radiation (RFR) in living cells.

Study co-author Igor Yakymenko from the National University for Food Technologies said the oxidative stress due to RFR exposure could explain not only cancer, but also other minor disorders such as headache, fatigue, and skin irritation, which could develop after long-term exposure.

“These data are a clear sign of the real risks this kind of radiation poses for human health,” Yakymenko said.

“ROS are often produced in cells due to aggressive environments, and can also be provoked by ordinary wireless radiation,” he added.

In 2011, the International Agency for Research on Cancer classified RFR as a possible carcinogen for humans. But clear molecular mechanisms of such effects of RFR were a bottleneck in acceptance of a reality of risk.

Yakymenko and his colleagues call for a precautionary approach in using wireless technologies, such as cell phones and wireless internet. (IANS)

High Exposure to Radio Frequency Radiation Increase Risk of Cancer

Interestingly, the team found that rats exposed to whole body RFR lived longer than rats unexposed to any radiation

Exposure to high levels of radio frequency radiation (RFR) — used in 2G and 3G cell phones — can increase the risk of cancer tumours in the heart, brain and adrenal gland, researchers have warned.

The study, led by the US National Institutes of Health’s National Toxicology Programme (NTP), looked at the effects of exposing rodents to extremely high levels of radiofrequency throughout the entire body.

While high levels of RFR caused cancerous tumours in the heart (found very rarely in humans), brain and adrenal gland, of male rats, the findings on female rats were ambiguous.

“The exposures used in the studies cannot be compared directly to the exposure that humans experience when using a cell phone. In our studies, rats and mice received radio frequency radiation across their whole bodies,” John Bucher, researcher from the NTP, said in a statement.

“By contrast, people are mostly exposed in specific local tissues close to where they hold the phone,” Bucher added.

For the study, the team housed the animals in chambers specifically designed for the study.

Exposure to RFR began in the womb for rats and at 5 to 6 weeks old for mice, and continued for up to two years, or most of their natural lifetime.

However, the RFR exposure was intermittent — 10 minutes on and 10 minutes off — totalling about nine hours each day.

In addition, the RFR levels ranged from 1.5-6 watts per kilogram in rats, and 2.5-10 watts per kilogram in mice.

“We believe that the link between radio frequency radiation and tumours in male rats is real,” Bucher noted.

Interestingly, the team found that rats exposed to whole body RFR lived longer than rats unexposed to any radiation.

“This may be explained by an observed decrease in chronic kidney problems that are often the cause of death in older rats,” the researchers noted.

According to the US Food and Drug Administration (FDA), while animal studies contribute to discussions on the topic, “this study was not designed to test the safety of cell phone use in humans, so we cannot draw conclusions about the risks of cell phone use from it.”

Since the exposure levels and durations in the studies were greater than what people experience, “we agree that these findings should not be applied to human cell phone usage”, the FDA said on Thursday. (IANS)
