A Danish study of more than 350,000 over 17 years concluded Thursday that there is no link between cellphones and cancer, reports ABC News.
The research, published in the journal BMJ, solidified the growing evidence from previous studies that even heavy cellphone users do not experience increased rates of cancer, ABC News continued.
Investigators noted that the study focused on cellphone subscriptions rather than actual use, so this will likely not be the last word on cellphone safety, reports the New York Times.
A 13-country study of 14,000 people last year came to no clear conclusion that cellphones and cancer were linked, but they did find enough heavy users diagnosed with a rare brain tumor to hint at the possibility that cellphones were carcinogenic, according to the Huffington Post.
After that study, the International Agency for Research on Cancer classified cellphones as "possibly carcinogenic."
Despite the U.S. Food and Drug Administration and the Federal Communications Commission both saying they have found no link between cellphones and cancer -- and the fact that cancer rates have not risen after the introduction of cellphones -- fear still persists, reports Time Magazine.
For example, MobileWise, an advocacy group that believes cell phones pose a risk, disputed the study, saying it was not long enough since brain tumors can take decades to form, reports CBS News.
