Anthropologists have discovered the oldest ever human tumor in the rib of a Neanderthal in Croatia. The Croatian discovery is the oldest by more than 100,000 years, writes Yahoo news.
Bone from the Neanderthal was excavated over 100 years ago from a cave near Krapina, which held more than 900 Neanderthal bones dating back over 120,000 years ago, and examined by experts at the University of Pennsylvania.
X-Ray’s showed that bone from the ribs had been hollowed out by a tumor still seen in humans today, known as fibrous dysplasia. These tumors are not cancerous but they replace the weblike inner structure of a bone with a soft, fibrous mass.
