Tumours grow through a process of Darwinian evolution, where cancer cells develop an advantageous mutation that allows them to survive and multiply, producing a population of cells which can mutate further.

Like a cruel form of mind control, some cancerous tumours can reprogram some immune cells to «block» other immune cells from attacking, leaving the tumour free to grow.
