Relax! Using your cellphone at work won't give you cancer

Relax! Using your cellphone at work won't give you cancer

There was a slight increase in a rare heart tumor discovered in the male rats, although the mice and female rats were unscathed.

The incidences of other cancers were not higher, statistically speaking, than the researchers would have expected to see in rats as they aged in general.

Results from the study indicated that the male rats which showed carcinogenic activity were exposed to a radiofrequency energy exposure rate "much higher" than the current standard, and that now FDA safety limits are set to include a 50-fold safety margin from observed effects of RF energy exposure, according to the FDA release.

EWG's 2009 Science Review on Cancer Risks and Children's Health summarized comprehensive studies showing a variety of health harms linked to long-term cellphone use. But there was overall little difference in the actual health outcomes of exposed mice and rats compared to their untouched counterparts by the experiment's end - some control groups even died sooner than those exposed to the radiation. They went on to say that the results still require "careful discussion", and that they would be participating in a peer review of the study, due to take place during March 26-28. And he isn't changing his cellphone use.

The complete results, extracted from studies involving about 3,000 laboratory animals, led NTP scientists to conclude the increased rate of malignant schwannomas in male rats was caused by exposure to the radiofrequency radiation. Bucher said the findings related to brain tumors rose only to the level of "equivocal evidence of carcinogenic activity".

Years of research have gone into figuring out the cancer risks of holding cellphones so close to our vulnerable human bodies. Various tumors were also observed in mice exposed to radio-frequency radiation. While the United States has transitioned to 4G, 4G-LTE and 5G networks in recent years, the 2G and 3G frequencies are still used in voice calls and texting. They said they some tissue and DNA issues but "we don't feel sufficient understanding to comment on their biological significance". Further, while some of the rodents developed various types of cancer, including brain, pancreatic, liver and prostate cancer, other cohorts did not, and a clear pattern was not discernible.

As for the weight issue, they saw changes in newborn rats and their mothers when exposed to high levels at the time of pregnancy and lactation.

"We don't have any idea really", Bucher said.

Years of research have still not reached a conclusion on whether or not cellphones cause cancer. The evidence for an association between cellphones and cancer is weak.

"International and US organizations and health experts have maintained their longstanding conclusion that the scientific evidence shows no known health risk due to the RF energy emitted by cellphones", said Justin Cole, a spokesman for the trade group.

Still, the Food and Drug Administration (FDA) seems content with the study in the short term while it continues to examine the wider evidence.

"Even with frequent daily use by the vast majority of adults, we have not seen an increase in events like brain tumors", Shuren added. "We believe the current safety limits for cellphones are acceptable for protecting the public health".
