Cancer cells come pre-programmed to execute a well-defined cascade of changes, seemingly designed to facilitate both their enhanced survival and their dissemination through the bloodstream. There is even an air of conspiracy in the way that tumours use chemical signals to create cancer-friendly niches in remote organs.
Rapunzel is a bit more relatable than the other princesses, especially because she doesn't even know that she's a princess until the very end of the movie. I like to think of her as the bohemian Disney princess. She's barefoot and living in a tower. She paints and reads... She's a Renaissance woman.
