In other words, we haven’t proven that there isn’t a risk, and it’s worth doing more research to try and discover if there is a risk because it would be a pretty big deal if there is...but it’s not an easy thing to control for.
I don’t think we’ll have an answer to this during this century, unless it conclusively _does_ cause harm (current studies indicate that it does not).
That said, I'm not saying they are carcinogenic, but I'd rather err on the side of caution. Short answer, I don't hold the phone near my head, I leave it out of my jeans pocket as much as possible, and have it on flight mode at night.
Given the recent news about there being small bits of asbestos mixed in, one has to wonder if that was the actual reason for it being on the list.
Others that I won’t be surprised if it bites us are Nitrates in food, Aspartame, Vaping, red meat, refined carbs.
