About Pancreatic Cancer
Where is the pancreas located?
The pancreas is pear-shaped and approximately 6-8 inches long. It has a wider end
called the head, the middle part called the body and a tapered end called the tail.
Refer to Figure 1. The head of the pancreas is on the right side of your body. It lies
close to the liver and the section of the small bowel called the ‘duodenum’. The tail is
close to the stomach on the left side of the abdomen. The pancreatic duct is a
channel that runs through the pancreas and empties digestive juices into the small
bowel. The common bile duct is another channel that drains bile from the gallbladder
and runs through the head of the pancreas connecting with the pancreatic duct to
form the Ampulla of Vater.

What does the pancreas do?
The pancreas has 2 main functions in the body:
• to make digestive juices (called enzymes) that flow through the
pancreatic ducts and help break down fats and sugars in the digestive
• to secrete hormones, like insulin, that affect how the body uses and
The part of the pancreas that produces the digestive juices is called the exocrine
pancreas and the other part that produce hormones is called the endocrine
pancreas. What is cancer and how does it affect the pancreas?
Normal cells grow, divide, and die in a control ed fashion that is regulated in the body.
Cancer is a disease where cells divide and grow in an abnormal, poorly controlled
manner where the balance of cell growth and death is disturbed. Medical research
has led to an increase understanding of these abnormalities and continues to be a
focus in the understanding of how to treat cancer.
Cells that continue to grow and divide unchecked become a malignant mass or
tumor that can affect how an organ works. The original site of the abnormal cell
growth is called the cancer’s “primary site”. In pancreatic cancer, the primary site is
the pancreas. Even when the pancreatic cancer is found in areas outside the
pancreas, such as the liver, the disease is still called pancreatic cancer.
Abnormal or unchecked cel s can also grow to invade nearby organs and structures.
Cancer cel s spread and invade organs by traveling to other structures in the body by
way of the lymphatic system and the blood stream. This spreading is called metastasis.
How common is pancreatic cancer and who is at risk?
The American Cancer Society estimates that 32,180 men and women will be diagnosed
with pancreatic cancer in 2005. It is the fourth leading cause of cancer death in the
United States. It most commonly affects patients in the 60-80 year age range, although
older and younger patients can be affected. Pancreatic cancer may be related to
exposure to cancer-causing agents called carcinogens.
Some factors that increase the risk of pancreatic cancer are:
• Cigarette smoking
• A diet high in fat and low in fiber
• Diabetes mellitus
• Chronic pancreatitis
• Family history (see below)
There is no reliable way to prevent pancreatic cancer, however, general cancer
prevention guidelines include eating a high-fiber, low-fat diet, exercising, and
avoiding smoking. Information Is pancreatic cancer hereditary? about genetic counseling at the University of Michigan can be found
Research is being done to better understand possible at www.mcancer.org or at the Patient Education Resource Center
hereditary factors in pancreatic cancer. There does (PERC) on level B1 of the Cancer Center.
seem to be a hereditary component in 10-15% of
patients with pancreatic cancer. Genetic syndromes such as
hereditary pancreatitis, hereditary nonpolyposis colorectal cancer, familial atypical
multiple mole melanoma syndrome, and Peutz-Jeghers syndrome are currently being
studied for their specific gene changes.
Families with medical histories of known hereditary cancer syndromes that include
pancreatic cancer should consider genetic counseling and testing in a research setting.
Patients who have a family history of colon cancer, pancreatic cancer, and melanoma
may be at an increased risk for pancreatic cancer.
What are the symptoms of pancreatic cancer?
Symptoms do vary and are related to the extent of disease and the location of the
tumor in the pancreas. The head of the pancreas is located close to the common bile
duct and duodenum (small bowel) so tumors located in the head of the pancreas
may grow and block these structures. Refer to Figure 2.
Artery and Vein Figure 2. The pancreas and surrounding organs Jaundice
Bile duct blockage can lead to jaundice in 70-85% of patients with tumors in the head
of the pancreas. Symptoms of jaundice include:
• yellowing of the skin,
• yellowing of the whites of the eyes,
• light-colored (clay colored) bowel movements,
• dark-colored urine and
Nausea, Vomiting, Weight Loss
Stomach emptying can be delayed when the duodenum is compressed. This causes
a feeling of fullness and contributes to symptoms of nausea and vomiting. These
symptoms are initially present in 35-45% of patients with pancreatic cancer. Patients
sometimes have a loss of appetite and nausea that leads to weight loss. In advanced
disease, up to 5% of patients have tumors that cause complete blockage of the
duodenum (small bowel). In this case, surgery may be done to bypass the blockage
and improve digestion. Fatigue
In more advanced disease, patients can have a feeling of being tired and fatigued.
There are many causes of fatigue in patients with cancer, Abdominal Pain
75-90% of patients with pancreatic cancer have abdominal pain. This may be
described as cramping or gas-like pain. Pain may also spread, or radiate, to the back
and shoulders. Blood Clots
There is an increased risk for blood clots in patients with pancreatic cancer. A blood
clot can be a first symptom of pancreatic cancer. The cancer itself causes changes
in the blood that increases the risk for blood clots. Some clots have no symptoms, but
swelling, pain and redness can be present in the area of a clot. Diabetes
The onset of diabetes mellitus (called simply, diabetes) or difficulty controlling blood
sugar levels is also associated with pancreatic cancer. Diabetes may be diagnosed
before or after the diagnosis of pancreatic cancer. Diabetes occurs when the body
does not produce enough of the hormone, insulin, or is unable to use insulin properly.
Insulin helps your body regulate the blood sugar level, so without insulin, blood sugar
levels are often high.
The pancreas secretes digestive enzymes, or juices into the small intestines. These
juices help digest food in the intestines. Patients with pancreatic cancer may not have
adequate amounts of these juices in the intestines. If this happens, food isn’t digested
normally. This is called pancreatic insufficiency.
Symptoms of pancreatic insufficiency include diarrhea and cramping often after
eating. This happens because food passes through the digestive tract not fully
digested. As the indigestible food passes through, it pulls water into the intestines that
causes diarrhea and cramping. Refer to page 38 for a discussion on management of
pancreatic insufficiency with enzymes.
