Would your hand get cancer in the long run? Wireless charging means
there is energized EM radiation coming out of the pad!
There's be no conclusive study to support the idea that EM radiation
causes cancer; but there is some epidemiological statistics that do
seem to support the idea.

Not as far as I'm aware - unless small/under powered studies. Link?

No industry group seems interested in finding out. The only studies
seem to measure the heating effect in jello as an indication of
potential threat to humans. Making the world a safer place for jello?

Probably

There has been some research that indicates that T cells are affected
by EM fields. T cells fight and prevent cancer; so the situation may
be that in the presence of a carcinogen or some hereditary
susceptibility to cancer, in combination with strong EM radiation one
may be more likely to contract cancer.

All these in vitro studies have little relevance to real-world situations.

Field strength falls off rapidly with distance so your choice of where
to locate the charging pad may make a difference...

I'm not going to chase down the refs:

https://en.wikipedia.org/wiki/Glioma

"Gliomas have been correlated to the electromagnetic radiation from
cell phones,

Lots of unrelated things are correlated. Means very little in its own.

and a link between the cancer and cell phone usage was
considered possible, though several large studies have found no
conclusive evidence, as summarized by the NIH's National Cancer
Institute review of the topic and its numerous citations, and the
FCC. However, further research is still being pursued to obtain more
robust evidence and verify that there is no relationship (the NIH's
National Institute of Environmental Health Sciences most recent press
release discussed an ongoing study showing mildly positive results,
although it appears there may have been issues with the control group
dying prematurely)."

That report on an on going study was from 2016. The full study has been
published and: "The full results of the National Toxicology Program’s study
of cell phones and cancer are finally in. They are somewhat complicated,
but ultimately do not support the idea that cell phones can cause cancer."

I find the lump on my head, helps keep my hat on.

I don't want to come out for or against, I'm an engineer and not a
biologist. I did work in the pharmaceutical industry and picked up a
smattering of trivia that may or may not enter into this.

Like I said, not my field. But I don't think there will ever be a
consensus of opinion on this subject, there is likely to be some doubt
no matter what individual studies show or don't show.

The important point to make is that it doesn't come down to a "consesus
of opinion". Scientific studies produce data upon which facts can be
drawn. No single study is perfect which is why for important topics many
studies are run. The aim being that each study has a slightly different
methodology and if they all get the same result that is strong evidence
to support it. However, scientists always look for alternative
explanations just in case there might be another way to interpet the
results, which is why you'll never get a (good) scientist or report
categorically saying one thing or another.

Given that human-generated EM radiation has been around for many decades
and it has been studied with not a single concrete result proving a link
between human cancer and EM, I'm quite happy to say there is no doubt
that wireless charging doesn't cause cancer. Just like wifi, mobile
phones, TVs, etc.


I'll remain neutral. No one seems to have designed a good study IMO,
and given the pervasiveness of EM fields, it may not be possible
without some seriously draconian efforts to control variables.
