Hmmm. It depends on the power, frequencies and distance to tissue. I remember a coworker at a GPS mfgr accidentially turned on a 440 MHz radio in high-power (25W) mode with only a whip antenna and received a nasty radio burn when he pointlessly/accidentally put his hand around it. That radio burn looked similar to a sunburn or maybe 20 seconds in the microwave. Increased risk of cancer, for sure. A fraction of a Watt…
Yeah no. Burning yourself on a hot stove does not increase your risk of cancer and that's the same thing which happened to your coworker.

I thought microwaves weren't high enough in the spectrum to disrupt DNA which is the main cause of cancer risk for gamma/x-ray? Individual waves don't have the energy to break bonds even for relatively high power transmitters, at least that's what I've been told.
I'm not a comms engineer but I've also been told the biggest risk microwave exposure is thermal burns. Especially to the eyes which have limited cooling ability and pain receptors
I am talking about the infrared range, which is above 300GHz.
The body also reflects terahertz radiation from the surrounding environment, even directly into other people's eyes. This has the bizarre side-effect of causing people to be able to "see" each other.

I'm curious to know the circumstances if you know what a skin burn from 20 seconds in a microwave looks like.

Cell phones emit RF signals that penetrate the body. Lightbulbs for the most part do not. I've always considered the notion of antennas important. Your circulatory system may act as antennas of all different lengths and that would put the received energy right into the blood where it can cause leukemia or other similar cancers. Just speculation of course, but the proposed mechanism applies to RF and not light bulbs.
> Lightbulbs for the most part do not. 1) Take a flashlight 2) Put a finger over the bulb and turn it on 3) Observe the surprising amount of light that passes through your finger.
Grandparent is right though since most of the blue and green light parts are reflected or absorbed in the top skin layers. Starting with red and infrared, deep tissue penetration is possible. The higher the frequency, the lower its ability to penetrate. That’s why RF can pass through bodies while UV light can’t.
I would be more worried about issues similar to the diesel gate scandal where manufacturers start forging radiation tests results. How much testing does the government do and how much is the industry self testing?
Unfortunately that appears to already be the case:
WiFi transmission power is almost always controlled by software, with no hardware limits. It’s very easy to override this and transmit above the legal limit, to the point where you could potentially damage the hardware itself.
X-rays and Gamma and all the way down to UV are ionizing which is why they are harmful. Radio waves are way below light and infrared as was stated. Forget body heat, why does no one care we are walking around 60w terahertz radiators in our home! Then we go outside and bathe in 1000 watt per meter sunlight which includes ionizing UV. Cell phones put out the equivalent of a low power LED light I am not sure way everyon…

About the blood-vessels-as-antennas theory, I just want to throw in that blood vessels absorb infrared light well (well duh, blood is quite dark), so at least at that frequency energy is very much absorbed, rather than passed through.
to continously connect with your friends just cover your superior areas (mainly head) in aluminium foil and reflect remotley some interest from a long distance by showing the finger ..
neural networks will explode like popocorn into microwave and you could rent your mental computation infrastructure to produce units such as bitcoins

Many skin cancer treatments have a similar process.
