“Cancer is related to age. If you strip out longer lifespans, it becomes clear that in the rich world the early 1990s were an inflection point. Since then, the age-adjusted death rate has been falling, slowly but steadily, year after year. In America the rate is now about a third lower than in the 1990s. The trend is similar in other developed countries.

What some scientists hoped would be a blitzkrieg has turned out to be a steady but successful war of attrition. Some victories have been spectacular. Childhood leukaemia used to be virtually a death sentence; now it has a five-year survival rate above 90%. Yet because cancer is not one illness, but a whole category, much of the progress has come not from big breakthroughs, but thousands of smaller advances in screening, surgery and drugs.”
