A hot surface burn is your cells getting destroyed by heat.
A sunburn is your cells self-destructing.
The sun throws off UV radiation, which might damage the DNA of a cell. Most of the time the cell detects this damage and self-destructs.
But it’s possible that the cell does not detect this damage, which might be in an area that stops it from replicating itself, and the body’s immune system might miss that malfunction.
So the cell starts replicating out of control, and that’s cancer.
