Who was it that was responsible for the discovery that there are mummies found with cancer as the stated cause of death? And which Pharaoh or Pharaohs was it found in?
Mummification wasn't limited to pharaohs, state officials could get mummified as well (while obviously not being buried in pyramids). In fact, the overwhelming majority of mummies found aren't pharaohs and most of them remain unnamed. E.g. the title of one article discussing a cancer case is "Colon cancer in a Ptolemaic mummy from Dakhleh Oasis". While I don't have the article itself, I'm pretty certain that it doesn't mention who that mummy was - merely when he lived (thanks to carbon dating).
