Cancer is cells that are growing and dividing out of control.
* They no longer control how fast they grow.
* They no longer listen to signals from the body telling them to stop.
* They don’t care about protecting their DNA… which means…
* They evolve quickly, and adapt.
* They can disguise themselve from the immune system.
* They can become resistant to drugs.
* Eventually… they can control their environment:
* They can “turn-down” the immune system.
* They can grow blood vessels so the tumour can grow bigger
