cancer is a product of the same evolutionary processes that lead to our own survival, or that of any other species or organisms. When a mutation occurs inside us, it thrives if it has developed the ability to evade our body’s defenses. Over the course of our lifetimes, we’re being thrown tons of twists by malignant cells, and it takes only a handful to turn on the immune system’s brake and start a cascade of malignancy. “It’s basically evolution at work in real time, a Darwinian survival system,” Dr. Lesokhin said.
