Mobile phones are not linked to brain and head cancers, a comprehensive review of the highest quality evidence available commissioned by the World Health Organization has found.
Led by the Australian Radiation Protection and Nuclear Safety Agency (Arpansa), the systematic review examined more than 5,000 studies from which the most scientifically rigorous were identified and weak studies were excluded.
The final analysis included 63 observational studies in humans published between 1994 and 2022, making it “the most comprehensive review to date”, the review lead author, associate prof Ken Karipidis, said.
“We concluded the evidence does not show a link between mobile phones and brain cancer or other head and neck cancers.”
Published on Wednesday, the review focused on cancers of the central nervous system (including brain, meninges, pituitary gland and ear), salivary gland tumours and brain tumours.
The review found no overall association between mobile phone use and cancer, no association with prolonged use (if people use their mobile phones for 10 years or more), and no association with the amount of mobile phone use (the number of calls made or the time spent on the phone).
“I’m quite confident with our conclusion. And what makes us quite confident is … even though mobile phone use has skyrocketed, brain tumour rates have remained stable,” said Karipidis, Arpansa’s health impact assessment assistant director.
