HISTORY: Egyptian Mummy Had Prostate Cancer; Lots More Ancient Peeps Probably Did Too. “Scientists report in a paper soon to appear in the International Journal of Paleopathology that the mummy, known as M1, died when he was between 51 and 60. He is the oldest case of prostate cancer identified in ancient Egypt, and the second oldest in the world (the oldest was in the 2700-year-old skeleton of a Scythian king in Russia). M1’s scans also show a malignant cancer that had spread to his spine and other areas around his pelvis.”
