Is Cancer a Man-Made Disease?
A new study suggests that cancer is a man-made disease.
Is the common nature of cancer worldwide purely a man-made phenomenon? That is what some researchers now suggest.
Still, other specialists in cancer and in human fossils have strong doubts about this notion.
Cancer is a leading cause of death worldwide, accounting for roughly one in eight of all deaths in 2004, according to the World Health Organization. However, scientists have only found one case of the disease in investigations of hundreds of Egyptian mummies, researcher Rosalie David at the University of Manchester in England said in a statement.
The rarity of cancer in mummies suggests it was scarce in antiquity, and “that cancer-causing factors are limited to societies affected by modern industrialization,” researcher Michael Zimmerman at Villanova University in Pennsylvania said in a statement. “In an ancient society lacking surgical intervention, evidence of cancer should remain in all cases.”
