Should you be worried about WIFI radiation?
These are radio waves – no different than those used to broadcast television programs – except that they are higher in frequency. They aren’t nearly as high a frequency as visible light and no one worries about getting cancer from visible light (ultraviolet light, on the other hand, causes skin cancer – but this is the minimum energy necessary to cause ionizations that can cause breaks in strands of DNA – which is the mechanism by which cancer cells can be created).
There is no credible evidence that non-ionizing radiation has any adverse health effects at all.
There is no radiobiologic mechanism that could explain such an association and no scientifically valid evidence that cancer has ever happened because of WIFI radiation
