Cancer, our Doppelgänger

After 3 occurrences of cancer within the family (2 dead, one will go any day now) I finally bought this book I have been meaning to read since years. Brilliantly written, very easy reading for the layman. And a great reminder that any day you wake up and are still alive and well, and no one in your family is dying, you must remember to be happy and cheerful.

"...This image - of cancer as our desperate, malevolent, contemporary doppelgänger - is so haunting because it is at least partly true. A cancer cell is an astonishing perversion of the normal cell. Cancer is a phenomenally successful invader and colonizer in part because it exploits the very features that make us successful as a species and as an organism. [AM: cell division, cloning, survival of the fittest, growth via evolution]

...When a chemotherapeutic drug or the immune system attacks cancer, mutant clones that can resist the attack grow out. The fittest cancer cell survives. This mirthless, relentless cycle of mutation, selection, and overgrowth generates cells that are more and more adapted to survival and growth. In some cases, the mutations speed up the acquisition of other mutations. The genetic instability, like a perfect madness, only provides more impetus to generate mutant clones.

Cancer thus exploits the fundamental logic of evolution unlike any other illness. If we, as a species, are the ultimate product of Darwinian selection, then so too is this incredible disease that lurks inside us."
