Cytosponge

A ‘pill on a string’ developed by researchers at the University of Cambridge could help doctors detect oesophageal cancer – cancer of the gullet – at an early stage.

The ‘Cytosponge’ sits within a pill which, when swallowed, dissolves to reveal a sponge that scrapes off cells when withdrawn up the gullet. It allows doctors to collect cells from all along the gullet, whereas standard biopsies take individual point samples.
