A recent international review finds no link between cellphone use and brain cancer.

Commissioned by the World Health Organization, the review included 11 experts from 10 countries who sifted through 5,000 studies published between 1994 and 2022. The final analysis was published in the journal Environmental International.

The organization was trying to determine whether greater exposure to radio frequencies commonly used by wireless electronics like cellphones might up the chances of a brain cancer diagnosis.

In the 63 studies it honed in on, the risk of brain cancer did not increase, even with prolonged cellphone use (defined as 10 years or more), among those who spent a lot of time on their phones or for people who made a lot of calls.

They also saw no increased risks of leukemia or brain cancer in children exposed to radio or TV transmitters or cellphone towers.

“These results are very reassuring,” lead study author Ken Karipidis said, according to a story in the Washington Post. While cellphone use has “skyrocketed, there has been no rise in the incidence of brain cancers.”

Concerns about a potential link emerged in 2011 when the International Agency for Research on Cancer, the WHO’s cancer agency, classified exposure to radio waves as a possible carcinogen to humans, the Post reported, but that was based on limited evidence.

Karipidis explained that since then, a “lot more studies have come out” on radio waves and they’ve been “quite extensive,” prompting the WHO to commission this review.

Also, newer generation cellphone networks, including 3G and 4G networks, produce “substantially lower” radio frequency emissions than older networks, review co- author Mark Elwood, an honorary professor of cancer epidemiology at the University of Auckland in New Zealand, told the Post.
