A 2015 study out of Germany has found evidence that exposure to radiofrequency radiation promotes the growth of tumors.
Radiofrequency radiation, also known as RF radiation, is emitted by cell phones, DECT cordless phones, wireless routers, bluetooth technology. microwave ovens, cell towers/antennas, and all types of wireless transmitting devices.
German researchers undertook this study after a pilot study was done which showed some evidence of an increase in tumors after exposing control animals to RF frequencies. Wishing to duplicate the pilot study but with the use of a larger control group of animals, the researchers went ahead and exposed large groups of laboratory mice to very low levels of RF radiation.
The levels used in the study were far below the current RF radiation safety levels issued by regulating bodies in Europe as well as in the US.
The mice exposed to the low level radiation developed tumors at an alarming rate compared to the control group, The tumors that developed in the mice were mostly concentrated in the lungs and liver. Lymphomas in the mice exposed to the radiation were also found to be significantly elevated as compared to the control group.
The researchers went on to hypothesize that the increase in tumors from RF exposure could be due to metabolic changes induced by the radiation.
In terms of cell phone use, the researchers concluded that, “Our findings may help to understand the repeatedly reported increased incidences of brain tumors in heavy users of mobile phones.”
