Study Claiming Cell Phones Cause Cancer Has Serious Flaws, U.S. National Toxicology Program Reveals
No need to panic. A large study in rats claims to show that cellphone radiation may cause cancer, but experts have cast doubt over the findings.
The US National Toxicology Program last week published the partial results of a two-year study, in which more than 1000 rats were exposed to differing levels of cellphone radiation for nine hours every day, for the whole of their lives.
No increases in brain or heart tumours were observed in female rats. But among male rats, around 3 per cent developed a type of brain cancer known as malignant glioma, and up to 6 per cent grew heart tumours called schwannomas.
