The pancreas forms part of the digestive system, responsible for producing digestive juices and hormones such as insulin. About 15cms long the pancreas sits behind the stomach and in front of the spine. It has a large rounded part – the head – at one end, and tapers into a tail at the other end.
Pancreatic cancer usually arises in the head of the pancreas (80%) and less commonly in the body (15%) and tail (5%).
