Clear evidence of a link between mobile phone radiation and cancer

Trigger mobile phones cancer?

A long-standing US study on the effects of radio wave radiation emitted by mobile phones has found clear evidence of a link between high exposure and the development of cancer.

Researchers at the National Institutes of Health (NIH) found in their recent research that cell phones may be associated with cancer. The doctors published a press release on the results of their study.

Tumors discovered on the heart, brain and adrenals

The purpose of the study was to examine the toxicity of mobile phone radiation in response to the ubiquitous use of devices in modern life. In their study on rodents, the experts then identified a link between the radiation of mobile phones and the development of heart cancer in male rats. There was also some evidence of links to tumors in the brain and adrenal gland in males.

Radiation exposure was very high

Radiation exposure in the study was well above the levels that most people would experience. However, the researchers showed that the link between radio frequencies and tumors, at least for rats, is present. The exposures used in the studies can not be compared directly with the exposure that people experience when using a cell phone, scientists point out. The studies exposed rats and mice to radio-frequency radiation throughout the body. In contrast, people are usually affected by radiation only in certain local tissues near their mobile phone. In addition, the levels of exposure and the duration of radiation during the study were stronger than the radiation that people experience through their phones.

Rats were irradiated daily for nine hours

The studies took a decade and cost more than $ 30 million. The tissues of the animals were examined for signs of tumors after irradiating most of their natural life for nine hours daily. The radiation began already in the womb.

Irradiated rats had more frequent tumors on the heart

The results of the investigations raise important questions, in particular because the lowest exposure levels were the maximum levels allowed for mobile phones, say the medical profession. The scientists found that male rats had a higher incidence of tumors on the heart compared to control rats that were not exposed to radiation. The experts believe that the relationship between radiofrequency radiation and tumors is real in male rats, but some critics doubt it.

Even modern mobile phones could be affected

The study also focused on 2G and 3G wireless signals, the most commonly used variants in cell phones at baseline. However, the researchers say their results are still relevant today, as most cell phones still use these bands next to Wi-Fi and 4G. (As)
