South Africa: earliest evidence of cancer discovered in fossils

In an accompanying paper in the same journal, researchers also identify the oldest tumour ever found in a human fossil, a benign neoplasm found in the vertebrae of the well-known Australopithecus sediba child, Karabo, at the Malapa site, also in the Cradle of Humankind. It was dated to around two million years in age. The oldest previously demonstrated possible hominin tumour was found in the rib of a Neanderthal and dated to around 120 000 years old. "Our studies show the origins of these diseases occurred in our ancient relatives millions of years before modern industrial societies existed," said Edward Odes, a Wits doctoral candidate. "Karabo's tumour was fascinating because it was in the back, an extremely rare place for it to be found in modern humans, but also because it developed in a child. This in fact is the first evidence of such a disease in a young individual in the whole of the fossil human record," said one of the researchers, Dr Patrick Randolph-Quinney of Wits and the University of Central Lancashire in the UK. Professor Lee Berger said the evidence of a tumour in a child questioned the assumption that modern humans developed them as a consequence of living longer. Both incidences of disease were diagnosed using state-of-the-art imaging technologies at the European Synchrotron Research Facility in Grenoble, France, medical CT at the Charlotte Maxeke Hospital in Johannesburg, and the micro-CT facility at the Nuclear Energy Corporation of South Africa.
