In 2011 (maybe 2013?[1]), the IARC put radiofrequency electromagnetic fields in group 2B,[0] which is basically “we're a little worried there might be a problem, but we haven't actually replicated it”.
I thought I remembered them taking it off that list sometime around 2017, but apparently they didn't. Nonetheless, this isn't them agreeing with the claim.
