Bronze age man 'inhaled smoke' which may have led to 'lung cancer', and disease then ate holes in his bones, experts believe.

The findings refute the belief that cancer is a mainly modern phenomenon that was rare in the ancient 'toxin-free' environment, it is claimed.
The academic research, reported this week in scientific journal PLOS ONE, was conduct by an international team comprising archeologist Vladimir Bazaliiskii, of Irkutsk State University, bioarcheologist Angela Lieverse of the University of Saskatchewan in Canada and biological anthropologist Daniel Temple, of George Mason University in the US.

The bones of a man aged 35 to 45 exhumed in Siberia date to the Early Bronze Age.
He suffered from either lung or prostrate cancer which eventually spread through his body from his hip to his head, say the international team.
'This is one of - if not the oldest - absolute cases of cancer that we can be really, really confident saying that it's cancer,' said Lieverse.
Similar cancer discoveries in remains estimated to be 5,000 to 6,000 years old have been made but these involve unconfirmed cancers or tumours later found to be benign.

'We've had this perception that it was almost non-existent in antiquity, because people didn't live the same kind of lifestyle that we live now. They lived in these pure, toxin-free environments and they were very active and ate natural foods,' she said.
'But it was more common than we like to think it was.'
The victim was a hunter-gatherer who would have burned wood fires to stay warm. Inhaling the smoke could have led to lung cancer, it is claimed.
The bones - arranged in the foetal position - were found in 1986 in a circular pit in the Cis-Baikal region. Men in this period were more commonly buried lying on their backs.
He was buried with a spoon in the shape of a serpent. His death would have been painful, she suggests. 'It's a tragic story. It breaks your heart to think of what he went through,' she said.

Temple added: 'You have this really aggressive bone destruction and at the same time you have rapid bone formation.' The ancient man was probably ill long before his death.
'This individual was in constant pain (and) likely expectorating blood,' he claimed. 'The people who lived with him probably knew something was wrong - they gave him something that symbolized illness had visited him,' he said.

'Grave goods have deep symbolic meaning, and when contextualized with these skeletal lesions, it is likely that the object reflected the circumstances surrounding this individual's illness and death,' he said.
The research was part of the Baikal-Hokkaido Archeological Project.
