The controversy began 10 years ago, when the International Agency for Research on Cancer (IARC) classified cell phones as “possible carcinogenic elements”. However, the World Health Organization (WHO) maintains that “to date no known harmful effects to health”.

To resolve this situation, an investigation by the University of Oxford and the IARC concluded that the use of mobile phones does not increase the risk of developing a brain tumor. Thus, this study published in the Journal of the National Cancer Institute ends two decades of speculation and fear of this false belief.

For the study, the researchers used data from the UK Million Women Study, a breast cancer research project that has a huge database, with information on one in four women born between 1935 and 1950.

After following 776,156 women for fifteen years, the authors have found that only 0.42% of the participants have developed a brain tumora similar risk percentage among users who use a mobile phone and those who have never had a device.

Investigators have reported no significant differences in the risk of glioma, meningioma, acoustic neuroma, or other tumors thought to be associated with wireless device use.

“We have strong and convincing evidence that normal mobile phone use does not cause cancer-related problems,” study co-author and IARC member Joachim Schüz told inews.

Does the time of cell phone use influence the risk of cancer?

Usage time was ruled out as a possible driver.

Usage time was ruled out as a possible driver.

As to whether the time of mobile use influences the risk of cancer or not, the researchers have not drawn a clear conclusion.

only the 18% of the participants he claimed to talk more than half an hour a week, so it is impossible to draw any concrete conclusions about the risk for people who use it much longer.

The main conclusion of the research is that the use of mobile phones in conditions normal does not increase the risk of brain tumors.

Many of the electronic devices in use today emit small amounts of electromagnetic waves. From microwaves, computers or televisions, to mobile phones.

The truth is that these radiofrequency electromagnetic fields emitted by wireless devices penetrate several centimeters into the head when talking to someone on the phone.

However, contrary to what many might think, it is not harmful to health. The main effect of this phenomenon is simply the superficial heating of the skin.

In this sense, the new research has not detected any increase in the risk of tumors in the areas potentially most exposed to these electromagnetic fields.

Moreover, the tumors detected are equally distributed on both the left and right sides, despite the majority of mobile phone use being with the right hand.

The latest generation smartphones, less harmful than the old ones

The authors highlight in their research that the emissions of current devices are “substantially lower” than those of previous generation devices. The current technology of 3G, 4G or 5G reduces the radiation of the devices even more than in its beginnings.

“These results support the growing body of evidence that mobile phone use under normal conditions does not increase the risk of brain tumours,” says Kirstin Pirie of the University of Oxford.
