What if I have 1500 laptops and cell phones in one room, for example, is the higher the radiation exposure, the greater the likelihood of cancer?
No, unless you sit in the microwave or it is damaged.
Otherwise, it is all non-ionizing radiation that cells in the body can't change.
No, unless you hang around the web on dubious Schwurbelseiten. After that everything is harmful. NON-ionizing radiation such as radio waves are NOT harmful because they do NOT change the composition of the tissue.
Microwaves are also non-ionizing, but have the resonance frequency of water in the microwave oven, which is why the water is heated. And this heating can damage the cells.

These devices do not emit radioactive radiation. And are therefore not carcinogenic
The answer only sounded to me that the microwaves would be ionizing. Since this is not the case, I just wanted to add it, shouldn't be a criticism
In fact, it is not known exactly, but it is most likely not harmful or only minimally harmful. The radiation from the devices does not have the necessary energy to directly knock an electron out of an atom (this is called ionizing) or to split a molecule. So no dangerous substances can develop in the body.
However, the body absorbs some of the radiation, which then becomes heat. If this heat is released in a very small area, it could potentially actually damage cells. Whether this happens at all and how many cells would be affected is not entirely clear and since the radiation to which we have been exposed has only increased in recent years, there are also no long-term studies. But you think about exactly what risk you are taking in radiation protection, so I don't assume that you will suffer any damage.
Cancer is the information itself.
Not everything that means "rays" harms. Not everything that is invisible is dangerous.
To achieve damage, I need a mechanism of action. With ionizing radiation, vulgo radioactivity, molecular connections are broken. The "thicker" the molecule, the sooner it is broken down into ions, which is why DNA hits it more often, which is not good for the life of the cell: either it dies or it becomes a zombie. Another ionizing radiation that is often underestimated is UV light. We all know about sunburn, but nothing else happened other than that the cell DNA etc. Broke. And sunburn increases the risk of cancer.
Since we humans are not electrical conductors and hardly react to magnetic fields, there's simply no mechanism for coupling radio waves, cell phone waves, power supply interference, … Into our bodies. (Yes, we have nerve conduction with electrical impulses, not with currents! So no electrical conduits.)
(There are exceptions: Standing directly in front of a RADAR antenna for aviation or seafaring is not a good idea. Soldiers in Alaska did that, it warms really well, but overheats parts of the brain. Not healthy…)
So: Whenever one speaks of "radiation", ask back what kind of character you should have, question the mechanisms of action, … Most of the time, a possible harmful effect dissolves in fairy tales. 😎
