Hello, everybody, mind, and spirit!

Specifically, Antonio Pocobi, I like your persistent inquiry! Let me see if I could provide you more information herein, so as to satisfy your insightful curiosity on Evolution and cancer cells.
1) Briefly, Evolution is a process by which all entities (spiritual and material) are created (or evolved) by the active, creative, and dynamic interactions of each elemental intrinsic properties (or propensities) and its immediate extrinsic factors (or opportunities) in its environment—(please see my book
Gods, Genes, Conscience for specific information on the Evolution of everything, that I coined in a new science of STEMology, for the study of space, time, energy, and matter in the vast active creative Universe above and beyond; and in all entities that are expressed on our unique planet Earth, including our human mind).
As such, the Evolution of cancer cells has no purpose or motivation at all, but only a change in cellular dynamics to their each unique microenvironments as being presented in our body. And, of course, the health of our body is all dependent on our intakes of healthy food, air, water, and exercise; and so on, and so forth.
2) Your statement about the varied different DNA modifications (or mutations) in normal and cancer cells, is correct! Congratulations!
3) Yes, by appropriate experimentations, the growth and distribution of cell populations can be derived and expressed in a fractal, whereupon every cell is unique in nature, as viewed from a quantum perspective.
Furthermore, in normal growth conditions—for cells that are grown by tissue culture biotechnology—the cell cycle (or the time for each cell division) in cancer is about 24-72 hours; whereas cell divisions in a normal cell population generally will cease at cell maturity; unless we’ve had artificially induced them to mutate and transform into tumor cells by either viruses, chemical carcinogens, or even ultra violet radiation, as we discussed before.
4) Last but not least, in Evolution, the genetic apparatus that you referred to is more opportunistic than deterministic in nature. Our gene expression will only operate whenever the immediate cell microenvironment is favorable biologically. In our healthy body—a multicellular organism that contains about 100 trillion cells, as I described before—the opportunity or chance for any genetic mutation, cell transformation, is enormous; not to mention the fact that we are now living in an Industrial Age of rampant air, water, chemical pollutions worldwide!
Thank you all for your kind attention and cooperation in this matter. Happy reading, thinking, and scrutinizing!
