Mobile Phone Radiation: “Clear Evidence” of Brain Tumors in Human

The effect of mobile phone radiation on human health is a subject of interest and study worldwide, as a result of the enormous increase in mobile phone usage throughout the world. Till 2015, there were 7.4 billion subscriptions worldwide, though the actual number of users is lower as many users own more than one mobile phone. Mobile phones use electromagnetic radiation in the microwave range (450–3800 MHz and 24-80GHz in 5G mobile). Other digital wireless systems, such as data communication networks, produce similar radiation.

The World Health Organization states that “A large number of studies have been performed over the last two decades to assess whether mobile phones pose a potential health risk.


In this study, rats and mice received radio frequency radiation across their whole bodies. By contrast, people are mostly exposed in specific local tissues close to where they hold the phone. In addition, the exposure levels and duration in our studies were greater than what people experience.

The lowest exposure level used in the studies was equal to the maximum local tissue exposure currently allowed for cell phone users. This power level rarely occurs with typical cell phone use. The highest exposure level in the studies was four times higher than the maximum power level permitted.

The $30 million National Toxicology Program (NTP) studies took more than 10 years to complete and are the most comprehensive assessment, to date, of health effects in animals exposed to radio frequency radiation (RFR) with modulations used in 2G and 3G cell phones. 2G and 3G networks were standard when the studies were designed and are still used for phone calls and texting.

The major strength of the study is that they were able to control exactly how much radio frequency radiation the animals received – something that’s not possible when studying human cell phone use, which has often relied on questionnaires.

The animals were housed in chambers specifically designed and built for these studies. 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. The RFR exposure was intermittent, 10 minutes on and 10 minutes off, totaling about nine hours each day. RFR levels ranged from 1.5-6 watts per kilogram in rats, and 2.5-10 watts per kilogram in mice.

The study included exposing rats and mice to high levels of radio frequency radiation (RFR) for nine hours a day for two years. Some evidence of links to brain and adrenal gland tumors in male rats were found, but in female rodents and male mice, signs of cancer weren’t clear.

The team discovered that 5%-7% of male rats developed malignant schwannomas (a type of nerve tumor) in their hearts, while 2%- 3% of male rats developed malignant gliomas (a deadly brain cancer). However, none of the rodents in the control groups developed these conditions.


Studies have shown that cell phones held near the head cause brain wave changes in 70% of people.

In another study, it has been reported that when you hold your cell phone up to your ear, 10% to 80% of the radiation from the phone penetrates two inches into your brain. In children, the penetration is even deeper. The potential danger is so widely accepted that insurance companies are beginning to exclude coverage for injuries related to wireless phone radiation exposure.


The National Toxicology Program (NTP) concluded there is clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors, according to final reports released today. There was also some evidence of tumors in the brain and adrenal gland of exposed male rats. For female rats, and male and female mice, the evidence was equivocal as to whether cancers observed were associated with exposure to RFR.
