What is Pancreatic Cancer?

Pancreatic Cancer Action developed several educational posters to help build awareness.  Here's the text from one of them.  To learn more or to download posters, visit ...

The pancreas is part of your digestive system. It is a gland (an organ which produces
hormones or other substances) which produces pancreatic juice (a fluid containing
enzymes which helps to digest food) and insulin (a hormone which controls the level of
sugar in your blood).

The pancreas lies at the back of the upper abdomen behind the stomach. It is about
15cm long and shaped like a tadpole. The large rounded section on the right hand side
of the body is called the head of the pancreas, the middle section is called the body
and the narrow part is known as the tail. The duct of the pancreas meets the bile duct
and together they form a channel through which the fluids produced by the pancreas
and bile duct flow out into the duodenum.

The term pancreatic cancer usually refers to the common pancreatic ductal
adenocarcinoma. Worldwide there are around 250,000 new cases each year; in
Europe that figure is more than 70,000. In the UK, approx. 7600 people are newly
diagnosed each year.

Pancreatic cancer occurs when malignant cells form in the pancreas. The disease
progresses rapidly but usually produces vague symptoms in the early stages.
Pancreatic cancer is often undetected until it has spread to other areas of the body
(metastasized). Jaundice (yellowing of the skin and whites of the eyes) weight loss and
abdominal pain can be the first signs of the disease.

There are two main types of pancreatic cancer:

Exocrine tumours - these make up about 90% of all pancreatic cancers and arise from the cells that line ducts in the pancreas that carry digestive fluid from the gland into the intestine. This type is called a ductal adenocarcinoma. Other exocrine tumours include types known as adenosquamous carcinomas and undifferentiated carcinomas.

Endocrine tumours – these are known as neuroendocrine tumours that sometimes produce hormones and are much less common.

Other uncommon tumours that can affect the pancreas include a type of lymphoma – a cancer arising from the lymphatic tissue in the pancreas; various cystic tumours and ʻpancreatic sarcomaʼ which develops in the
tissue that holds the pancreatic cells together. There are also tumours that arise from other tissues, such as the bile duct (cholangiocarcinoma), Ampulla of Vater, Ampullary adenocarcinoma, or duodenal
adenocarcinoma, which may present with similar symptoms but which have different treatments and importantly very different prognosis. 80% of pancreatic cancers occur in the head of the gland, less commonly in the body (15%) and tail (5%).

The causes of pancreatic cancer are not known. However, major risk factors include smoking, obesity, diabetes and hereditary conditions associated with predisposition to cancer. Speak to your doctor if two or
more close relatives have had pancreatic cancer.

There are several ways to treat pancreatic cancer:
o Surgery to remove the cancer.
o Chemotherapy, or a combination of chemotherapy and radiotherapy.
o Surgical bypass of the cancer.
o Insertion of an expandable metal or plastic stent in the bile duct
o Symptom control and optimisation of quality of life
