A study conducted by the World Health Organization (WHO) has found no link between smartphone use and the risk of brain tumors. Although cell phones have become more widespread in recent years and people are spending more time on them, exposing them to more radio waves, the number of brain tumors has not increased at the same rate, they say.

Such and similar studies have been conducted regularly in this millennium. As early as 2001, a Danish study found no risk of cancer from cell phones. Still, there are always concerns about potentially dangerous cell phone radiation. But among teenagers and their still young brains, one study found that mobile phone use did not increase the risk of tumors in children.

This has now been done by a Further study The study “The effect of exposure to radio frequency fields on the risk of cancer in the general population and working people” was not only initiated by the WHO but also partly funded by the WHO. It affects people who not only make long cell phone calls but have been using cell phones for more than a decade.
The study used 63 studies conducted between 1994 and 2022, conducted by 11 different groups in 10 countries, including the Australian Government’s Radiation Protection Agency. In addition to smartphones, these studies also looked at televisions and baby monitors and the effects of radio frequencies on people.
The risk of cancer has not been proven, but it cannot be ruled out
None of these studies found an increased risk, explains Mark Elwood, one of the editors of the WHO study and professor of cancer epidemiology at the University of Auckland in New Zealand. This meta-study covered adult and pediatric brain tumors as well as pituitary, salivary gland and leukemia cancers. In addition to the radio frequencies of smartphones, it was also about base stations and other transmitters, as well as the signals that employees are exposed to during their professional activities.
Despite these studies and the link between mobile communications and the occurrence of brain tumors, which has not yet been found, such cases cannot be completely ruled out. That is why IARC, the International Agency for Research on Cancer, which is part of the WHO, continues to classify mobile phones as “possibly carcinogenic”. Therefore, further investigations will be carried out.
