Cancer could not do what it does without genetics behind it. The genetics must be in opposition to host genetics, because evolution does not allow the host to develop self-destructive characteristics.

Molecular biologists have found that there is a constant battle in cells between destructive forces and host-favorable forces. The destructive forces result from clutter in the DNA. The clutter must get into the DNA through external sources, or time would remove it. But it takes a lot of time to remove a lot of clutter. So the destructive influences can build up significantly before being removed. While the bad DNA is being removed, more is being added, so the battle never ends.

This dynamic plus the complexity of cancer means cancer has its own DNA. In fact, there would be no other reason for cancer to spread through tissue than to replicate its DNA.

So why haven't geneticists found the cancer DNA? Molecular biologists sort of are seeing it, but they are viewing the source near the DNA and not correlating it with the end results.

The cancer DNA (possibly RNA but probably DNA) would be moving from host to host without being surrounded by a coat as other pathogens use. Cancer could do that by wrapping DNA around a protein to hold it in place. It's conceivable that large enough chains of DNA could be carried from host to host when wrapped around a protein. DNA exposed on the outside of the particle would be invisible to the immune system which cannot view genetic material as foreign matter.

After the cancer DNA gets into the host, it embeds itself into the host DNA in a manner similar to retroviruses. Being embedded in the host DNA creates longevity. From the host DNA, a pathogen can act for a lifetime.

It is estimated that eight percent of human DNA is old retrovirus DNA. That DNA has become nonfunctional over time. And more recently, the view is that much of that old retrovirus DNA gets put to use for new functions for the host. A lot of the mysterious DNA in a genome is likely to be carried there through horizontal gene transfer from other species—another recent concept that was not known until it was observed with GMOs in the 1990s.

Embedded DNA as retroviruses or cancer has the potential to be activated whenever the defenses of the host are weakened. This effect is extremely visible for cancer. People tend to get cancer following health problems which includes old age and exposure to harsh chemicals or radiation damage. Those factors weaken defenses allowing embedded DNA to overwhelm the defenses and become active.

However, radiation appears to be creating a different result in being dose dependent. It appears that some or all cancers use mutation rates as a method of spacing their activity, so they don't destroy too many host individuals. Radiation determines mutation rates and speeds up the clock for timing cancer activity rates. Mutagenic chemicals appear to do the same thing.

It should be possible to locate DNA wrapped around a protein through modern DNA analysis. But it would need to be specifically looked for, and apparently, no one is looking. The descriptive material indicates that the problem is in the host DNA, which eliminates any need to look for separate, pathogenic DNA.

Scientists study by looking through a straw due to the complexities they are wrapped up in. Also, they have to convince someone to finance and support their work, which means aligning upon usual assumptions. So no one is looking for the pathogenic cancer DNA that moves from host to host.

There may also be the assumption that the public should not be informed of pathogenic DNA for cancer to prevent undue concerns from developing. That mentality is often seen in persons who promote darkness as the solutions to problems. It is an unrealistic attitude. There has never been anything gained by darkness, while all solutions to problems require the light of evaluation.
