Scientists suggest that cancer is purely man-made

14 Oct 2010 - Cancer is a modern, man-made disease caused by environmental factors such as pollution and diet, a study by University of Manchester scientists has strongly suggested. The study of remains and literature from ancient Egypt and Greece and earlier periods - carried out at Manchester's KNH Centre for Biomedical Egyptology and published in Nature - includes the first histological diagnosis of cancer in an Egyptian mummy. Finding only one case of the disease in the investigation of hundreds of Egyptian mummies, with few references to cancer in literary evidence, proves that cancer was extremely rare in antiquity. The disease rate has risen massively since the Industrial Revolution, in particular childhood cancer - proving that the rise is not simply due to people living longer. Professor Rosalie David, at the Faculty of Life Sciences, said: "In industrialised societies, cancer is second only to cardiovascular disease as a cause of death. But in ancient times, it was extremely rare. There is nothing in the natural environment that can cause cancer.
