"Researchers looking at almost a thousand mummies from ancient Egypt and South America found only a handful suffered from cancer when now it accounts for nearly one in three deaths. The findings suggest that it is modern lifestyles and pollution levels caused by industry that are the main cause of the disease and that it is not a naturally occurring condition. The study showed the disease rate has risen dramatically since the Industrial Revolution, in particular childhood cancer – proving that the rise is not simply due to people living longer."
