I doubt that you can find a scientist doing research on radiations effect on the body that dogmatically has said that "non-ionising radiation _can not_ cause cancer". I will personally call this scientist up and lecture him/her on the merits of doing science scientifically.
So if you "doubt" the dogma by saying "non-ionising radiation _can_ cause cancer" every scientist, and me, can go "Fk yeah, thats a working hypothesis, go prove that and bring society forward".
But if you would say that "non-ionising radiation _causes_ cancer" you are "stupid" in the way that you don't base that sentence on the current state of science and you are just making things up because you have been "working with biologists for many years" and you are a proud user of Common Sense™.
Feynman did in 1974: http://calteches.library.caltech.edu/51/2/CargoCult.htm
In light of these things, my working hypothesis is scientists can dogmatically claim things too.
...and it is not justified to make that assumption, because there is reason to believe that there is another possible pathway. DNA is known to be conductive, and it is known that due to the shape of DNA in chromosomes it can act as a fractal antenna and non-ionizing electromagnetic radiation can induce currents in it.
It's also know that damage to DNA can change the conductivity of the damaged section. Some major researchers suspect that part of the mechanism cells use to detect and repair DNA damage makes use of this by looking for sections of DNA where the conductivity is not what it should be.
If this does turn out to be part of how damage is detected, then it is possible that currents induced by non-ionizing electromagnetic radiation when the DNA acts as a fractal antenna could confuse the repair mechanism causing it to fail to recognize and repair damage that would normally be found and dealt with.
Here is a submission from a little over a year ago about the fractal antenna aspect of DNA: https://news.ycombinator.com/item?id=9447964
See my comment in that discussion for some more information on the possibility that this is connected to DNA repair and a link to one of the major research groups that is looking into this stuff (Jacqueline Barton's group at Caltech).
Non-ionizing radiation can cause chemical reactions (photochemical, heating, burns) that damage cells and might lead to increased cancer risk.
I really doubt if that is the case with mobile phones but I think it makes more sense to look at the epidemiological data rather than make a bunch of hand wavey arguments about the radiation. There are a hell of a lot of cell phone users and if there is a risk worth being concerned about I think it should have shown up before now.
The negative effects are widely believed to have been caused by a 750W radar jammer, which frequently radiated the ship deck. There hasn't been established a clear cause-and-effect link.
Short of some indication that they were turning on the jammer all the time in the workshop I would sort of think chemical exposure would be a more likely explanation.
Sadly many areas of debate attract cranks in larger than usual numbers and the health effects of electromagnetic radiation is one of them. So people get rather weary of fighting the same battles again and again and tend to become a little flippant in their replies.
This is a bit overly general. Many of us who are highly educated and traditionally intelligent battle with imposter syndrome. We're just the ones who you won't find out there acting like we know everything.
The idea that this is often the case it likely more a matter of "the squeaky wheel" than scientific fact.
You also setup a straw man. Any scientist or thoughtful person says "there isn't a known/proven" link between non-ionizing radiation and cancer and so far most evidence seems negative.
Of course there is a lot we don't know. That doesn't mean we are incapable of making any statements about anything at all. If cell phones caused a significant risk in the rise of cancer (say 1-10%) we'd have easily seen that by now. We haven't. This study didn't see it either... In fact the rats exposed to radiation lived longer than the ones not exposed!
So what we can confidently say is that if cell phone radiation causes cancer, it is an extremely minor contributor. In all likelihood it's contribution is zero, but that is also unproven and should be further studied.
Even if the values were only rough estimates I feel like this would put the real risks more into perspective.
No matter how smart you think you may be, you simply don't know what you don't know, as you allude to later in your comment.
We live in an age of relative technological ignorance. Let's keep a proper perspective. In a few centuries, people will look back at what we know today and laugh. (Infinite examples could be given. Only 100 years ago people said man would never fly, etc. )
Such biologists may even believe they know how cells divide, because they've observed stages of cell division and given them fancy Latin names.

> A spontaneous tumor incidence of 45% was noted in 360 Sprague-Dawley rats (179 males and 181 females) and a 26% incidence was seen in 254 Swiss mice (101 males and 153 females) used as untreated control animals in an 18-month series of carcinogenesis experiments.
A tiny increase in cancer over a large base rate is going to be tricky to find.
So when it comes to cell phones, do those microwaves merely warm human tissue very slightly, or might it occasionally be concentrated in a way to cause micro-burns? Supposing the body is repeatedly having to heal tiny microwave burns, it wouldn't be surprising at all if cancer risk is increased.
I did a physics degree at uni, and then spent many years working in genomics. And I've never (even before the biology work) assumed the "non-ionising radiation can not cause cancer" to be a true statement. You can only come to that conclusion if you assume that ionisation effects are the only pathways that can cause cancer.
After working with biologists for many years I've come to the understanding that biology is extremely complex, we have an extremely limited understanding of it, and there could be any number of as yet undiscovered effects of non-ionising radiation on cellular biology.
I would hope that as more of these studies are done (this is not the first and probably wont be the last) that we would hear less of this dogma spouted by supposedly smart people, but I doubt this will happen. It doesn't matter what you do, intelligence and education often go hand in hand with ego and a feeling of infallibility. And the dismissive "non-ionising radiation can not cause cancer" people never miss an opportunity to tell you that doubting this "proven fact" makes you stupid.
