Bone Cancer Apparently Existing Since 120,000 Years Ago

Cancer is not only a disease of modern people, because it turned early humans have experienced a similar illness. It is revealed from a fossil found in Croatia, which has bone cancer. This discovery once listed as the oldest human bone cancer in history.

The tumor was found at Neanderthal fossil rib, which early humans found in Europe, Central and West Asia. This discovery is surprising because supposedly closely related to Neanderthals living in short -term, which is only about half of the old man's life today.

Bone specimens studied were collected from Krapina rock shelter, located about 34 km north of the city of Zagreb, Croatia. More than 900 human bones found during the excavation of the year 1899-1905. The results of radiometric examination and tooth enamel showed bone of this site is between 120000-130000 years.

"This is a young adult Neanderthal man. Krapina has produced one of the greatest examples of human skeletal remains accumulated from Upper Pleistocene sites, " said the researcher, Dr. David Frayer, who is a biological anthropologist at the University of Kansas as reported by Medical Daily, Friday.

Before the advent of these findings, bone cancer oldest ever found to be present in ancient Egyptian mummies who lived 1000-4000 years. However, tumors are found in the fossil Nenaderthal much older, beat specimens from Egypt with more than 100,000 years old.

In a report published the journal PLoS One, the results of X-ray examination showed the fossils contained in the 'fibrous dysplasia', a type of benign tumor most commonly found in current human ribs. This disorder is characterized by the appearance of soft fibrous tissue that replaces normal bone core.

The soft tissues are then expands and weakens bones and can lead to fractures. However, this finding was not the oldest ever discovered cancer. Previously been found to cause tumors in 350 million years old fossil fish from Cleveland, Ohio.

"The diagnosis is made by an experienced radiologist, Dr. Morrie Kricun, which has identified hundreds of disease in people who are hospitalized the University of Pennsylvania, " said Frayer.
