The camera you can swallow: New capsule could help detect early stages of cancer of the oesophagusGround breaking device the size of a large multivitamin pillCaptures microscopic images that detect changes in cells By James Black PUBLISHED: 21:47 GMT, 13 January 2013 | UPDATED: 07:53 GMT, 14 January 2013 A swallowable camera-in-a-capsule could help doctors spot early signs of oesophageal cancer, research has shown. The hi-tech transparent device is about the size of a large multivitamin pill. It contains a rapidly rotating laser that shines a beam of near-infrared light onto the wall of the oesophagus, or gullet, the pipe that carries food to the stomach.
