no expert (although I am a cancer survivor) but I suspect that it’s immensely difficult to study cancer in ancient human remains....
how many types of cancer cells will survive over centuries?
how many ancient human remains have even been tested in the appropriate ways to detect evidence of cancers?
sounds like someone went off half-cocked and half-assed b/c they had a ‘political’ point they wanted to make against ‘modern’ civilizations??
They can do dna analysis of mummies. I don’t suppose finding evidence of tumours is all that difficult.
