Pancreas [SEP] Introduction
Inflammation of the pancreas is known as pancreatitis, with common causes including chronic alcohol use and gallstones. Because of its role in the regulation of blood sugar, the pancreas is also a key organ in diabetes mellitus. Pancreatic cancer can arise following chronic pancreatitis or due to other reasons, and carries a very poor prognosis, as it is often identified when it has spread to other areas of the body. The word pancreas comes from the Greek πᾶν (pân, “all”) & κρέας (kréas, “flesh”). The function of the pancreas in diabetes has been known since at least 1889, with its role in insulin production identified in 1921.
