We tend to think of cancer as a ‘modern’ illness because its metaphors are so modern. It is a disease of overproduction, of sudden growth, a growth that is unstoppable, tipped into the abyss of no control. Modern cell biology encourages us to imagine the cell as a molecular machine. Cancer is that machine unable to quench its internal command (to grow) and thus transform into an indestructible, self-propelled automaton.
[Adapted from The Emperor of All Maladies by Siddhartha Mukherjee]
