What if cancer is the few remaining fully competent cells remaining in a truly diseased organ, that are trying to escape the mothership?

These cells are growing irrespective of the rest of the organ, eventually escaping (metastasis), and de-differentiating to the point that they don't have just 2 copies of our DNA.

They have way more.

Cancer is cells escaping from a truly diseased environment.

The final frontier of organ disease.

Maybe this is related to the desire to escape earth and start something new?
