Why dermaneedling/dermarolling can not cause skin cancer

In order for cancer to occur, a DNA strand need to be fully severed, which is referred to as a double-strand break. Single-strand breaks can be easily and quickly repaired by the body. Double strand breaks can occur as an effect of ionizing radiation, aggressive chemicals, viral infection or even mechanical cutting action, as is the case with asbestos fibres smaller than 1 ?m, because that is a size small enough to be able to penetrate a chromosome. In addition to their small diameter, asbestos fibres, due to their crystalline nature, are perfect knives in the sense that their cutting edge is perfectly sharp and straight on the molecular level, and thus able to cut DNA like a razor blade cuts a strawberry.

It would stand to reason to assume that needles would similarly be able to cause cancer, but fortunately that is not the case, otherwise tattoo artists would have gone out of business a long time ago due to class action lawsuits, legislation and insurance companies refusing to insure them, and people would warn against getting tattoos because everyone would know that they would increase the risk of skin cancer, which they don't.


The reason needles can't cause DNA damage is because even the sharpest needle tips are so big, compared to our chromosomes, that it would be like trying to cut a strawberry with the blunt end of a broken banana. This is the point of a needle in comparison to a red blood cell:


People have called this picture a "hoax" and they claim that in reality, red blood cells are much smaller. That would support our claim even more, but this photo is real. Its maker is Steve Gschmeissner and he used a scanning electron microscope. The only modification is artificial coloring. Now let's see how big chromosomes are:



Chromosomes are about the same size as red blood cells.  It's clear to anyone with a grasp of basic physics that it is impossible for a needle to even make a dent in a chromosome, let alone break the molecular bonds in its very much smaller DNA strands. The tip of the needle would simply push the chromosome out of its way, especially on such a microscopic scale, where mass inertia decreases by the third power of the linear size (diameter) of the structures. Cutting a DNA strand with a needle tip would be literally as hard as cutting a steel cable with a piece of styrofoam the size of the Empire State Building. It is a physical impossibility - the laws of physics prevent it.

It is theoretically possible though that there is a greater chance that the UV from the sun causes cancer in freshly needled skin, because it can be imagined that the UV can easier reach "open" skin. That is why the skin has to be protected against the sun, a couple of days after dermaneedling. But the needling itself can do no harm.
