The final analysis included 63 studies from 1994 to 2022.
There is no link between mobile phone use and an increased risk of brain cancer, according to a new study commissioned by the World Health Organization of published evidence available worldwide.
Despite the dramatic increase in the use of wireless technology, the incidence of brain cancer has not increased accordingly, according to the study published Tuesday. That applies even to people who make long phone calls or those who have been using their cell phones for more than a decade.
The final analysis included 63 studies from 1994 to 2022, assessed by 11 researchers from 10 countries, including the Australian Government’s Radiation Protection Authority.
The study assessed the effects of radiofrequency radiation, used in cell phones as well as televisions, baby monitors and radars, said co-author Mark Elwood, professor of cancer epidemiology at the University of Auckland in New Zealand.
“None of the major questions studied showed increased risks,” he said. The study looked at brain cancers in adults and children, as well as cancers of the pituitary gland, salivary glands and leukemia, and at risks from the use of mobile phones, base stations or transmitters, and occupational exposure. Other types of cancer will be presented separately.
The study follows similar work. The WHO and other international health bodies have previously said there is no definitive evidence of harmful health effects from cell phone radiation, but have called for more research. The International Agency for Research on Cancer (IARC) currently classifies such radiation as “possibly carcinogenic,” or Class 2B, a category used when the agency cannot rule out a potential link.
The agency’s advisory group requested that the classification be reassessed as soon as possible, taking into account new data since its last assessment in 2011.
