The researchers found bone osteoarthritis in a 240 million-year-old tribadic tortoise, whose appearance is identical to that of a bone sarcoma.
The medical study helps to provide more data on the history of cancer and its understanding.
The study was conducted by Yara Haridi and other researchers in Berlin, Germany, and published in the Journal of Gamma Oncology on February 7th.
The researchers said that studying old diseases is a vital way to understand the evolution of pathogens and systems. Immunity and healing mechanisms.
They explain that their studies provide a case of bone sarcoma, a very malignant bone tumor, in the thighbone of a turtle (Pappochelys rosinae).
The appearance of the tumor on this sample corresponds to bone sarcoma in humans today.
"This study provides evidence that tumor cell growth occurred early in the tribadic period and that cancer is not a recent physiological defect, but an inherent weakness of evolutionary history. vertebrates, "said the researchers.
