What was the earliest human carcinogen ever identified?

    Percival Pott identified soot as a carcinogen causing scrotal cancer in chimney sweeps in the late 1700’s. This is likely to be the first identification of a known carcinogen. Cancer itself is not a new phenomenon, however. Bone tumors have been found in Egyptian mummies dead for 5000 years. Evidence of tumors is even found in dinosaur bones from the Jurassic period.
