Personally I don't believe RF will be found to cause cancer. DNA mutation in ordinary cells is completely different process.
Really? Please explain the difference. Why is UV radiation linked to skin cancer, or ionizing radiation linked to various forms of cancer? My understanding is that it's DNA damage causing a change in cell cycle (eg. something wrong with the checkpoints) through activation of some oncogen (extremely simplified version).
DNA mutation outside gametes is insignificant unless it causes change in behavior. The only mechanism that springs to mind for a small number of cells to cause damage is cancer. Of course if the change effects a significant fraction of the cells, you might be in trouble. But it would be more like accurate radiation sickness at that point, not a small cumulative effect.
It is pretty natural process if you believe Darwin was right.
Which is why there are various mechanisms to repair DNA damage. It only tends to become a problem when these mechanisms get overwhelmed. This is why some exposure to UV (eg. sunlight) is usually harmless, but too much is associated with skin cancer.
RF exposure might be gently pushing towards malign mutations path. Or it might be not. This will take a good few generations to prove. I know jack about this.
Sure, mutations in gametes may cause birth defects. Do you have a proposed mechanism for low energy electromagnetic radiation to cause eg. point mutations? A claim like 'this may cause troubles in 70 years' is hard to verify. The only thing we can say is that we haven't found a strong correlation yet. Plus the logical issue of proving the absence of harmful effects. Is there any substance or technology that has been proven to be harmless? Even oxygen may cause harm if the concentration in the blood is too high (decompression sickness).
