How cancer starts: how a normal cell turns into cancer

An elephant has about a hundred times more cells than you, and yet it is less likely to die of cancer. Your cells, too, copy themselves under strict rules, and it takes a lot to break them all. Follow one mole for fifty years to see how: copying mistakes in DNA, the genes that work like an accelerator and a brake (oncogenes and tumour suppressors like p53), why cancer mostly comes late in life, how a tumour feeds itself and spreads, how T cells hunt it, and the ideas behind chemotherapy, targeted drugs and immunotherapy.
