From The Independent:
Archaeologists excavating a graveyard in Portugal have discovered an ovarian tumour that is hundreds of years old.
The type of tumour, known as a teratoma, often contains a range of body tissues, such as hair and teeth, that form when cells that should become eggs instead develop into other tissues.
It was discovered at a graveyard next to the Church and Convent of Carmo, which is believed to have been used between the early 1400s and 1755, when it was badly damaged in an earthquake.
The discovery was made during excavation work of 42 graves in 2010 and 2011 but the tumour was only recently identified.
