Photon energy argument against cell phones causing cancer

AI Thread Summary
Microwave radiation emitted by cell phones is non-ionizing, meaning it lacks the energy necessary to break molecular bonds or directly damage DNA, which is a common concern regarding cancer risk. The energy of microwave photons is in the meV range, while molecular bonds require energy in the eV range to be disrupted. Consequently, the primary effect of cell phone radiation is a slight increase in tissue temperature, not cellular damage. The discussion highlights a need for scientific evidence and data to support claims about cell phones causing cancer, emphasizing that fear often drives public perception rather than factual information.

I remember reading on this forum (probably) about how it was physically impossible for cell phones to cause damage to DNA. A microwave photon has energy in the meV range. My biology and chemistry aren't all that great, and what little I could properly google gave me the idea that molecular bonds are on the order of a few eV. If these numbers are right, it seems to make sense that microwave emissions from cell phones can't do damage in the sense that they directly screw with DNA to cause cancer (as is the typical public perception). Is this about right?

Indeed. Microwave radiation is non-ionizing. It doesn't contain near enough energy to break bonds. The most a cell phone will do is heat up the water and in turn, the tissue in its general vicinity by a fraction of a degree.
 
The thing I'm wondering is what the argument for cancer being caused by cell phones is? I want actual numbers and ... you know, science.

People love to scare themselves. Why do you think horor movies are so popular?

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
