Cancer cells break the rules of normal cells. They divide when they should not, do not die when they should, rob other cells of essential supplies, shirk their cellular jobs and pollute the extracellular space. While cooperating cells curb excess growth and proliferation, cancer cells often evade growth-suppressing signals. Cooperating cells have limited lives, but cancer cells resist cell death and hide from an immune system that would typically destroy them. Normal cells distribute nutrients and chemical signals essential to survival, but cancer cells grow extra blood vessels to grab more resources for themselves. These contrasts show us that cheating is not merely a metaphor for cancer. It is a description of cancer’s cellular reality.
