They do have adaptive pressure. 100s of millions of years of single cell evolutionary instincts live within our cells and the desire to survive. Being a multicellular organism is a relatively new learned behavior, and a human cell returning to that old mindset is basically cancer.

The only problem is that these individually minded (cancer) cells have every ability of your healthy cells and have basically stopped caring about the greater whole and care about themselves. Then they evolve at a micro level for their survival to fend off chemo, immune system, radiation etc. All it takes is one adapted/surviving cell to come back strong.

The sophisticated mechanisms for evasion exist because they have all the methods of evading your immune system that healthy multicellular organisms need to function and they multiply and increase their mutation rate to try new methods to survive and thrive.

I view cancer cells as single cells to understand their behavior with the adaptations of all the healthy cells returning to their “baser instincts”.
