Hatshepsut died as she approached what we would consider middle age given typical contemporary lifespans in her twenty-second regnal year. The precise date of Hatshepsut's death—and when Thutmose III became the next pharaoh of Egypt—is considered"Year 22, II Peret day 10" of her reign, as recorded on a single stela erected at Armant or 16 January 1458 BC. This information validates the basic reliability of Manetho's king list records since Hatshepsut's known accession date was "I Shemu day 4" (i.e., Hatshepsut died nine months into her 22nd year as king, as Manetho writes in his Epitome for a reign of 21 years and nine months). No contemporary mention of the cause of her death has survived. In June 2007, there was a discovery made in the Valley of the Kings. A mummy was discovered in the tomb of Hatshepsut's royal nurse, Sitre-In. A tooth fragment found in a jar of organs was used to help identify the body to be Hatshepsut's. If the recent identification of her mummy is correct, however, the medical evidence would indicate that she suffered from diabetes and died from bone cancer which had spread throughout her body while she was in her fifties. It also would suggest that she had arthritis and bad teeth.<br>
