Pancreatic Cancer


Pancreatic cancer is the growth of cancer cells in the pancreas. The pancreas is a long, flattened pear-shaped organ in the abdomen. It makes digestive enzymes and hormones, including insulin.

Cancer occurs when cells in the body divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant growths. These growths can invade nearby tissues. Cancer that has invaded nearby tissues can then spread to other parts of the body.

It is not clear exactly what causes these problems in the cells, but it is probably a combination of genetics and environment.

Risk Factors

Pancreatic cancer is more common in men, and in people aged 40 years and older. Other factors that may increase your chances of pancreatic cancer:

  • Smoking and using smokeless tobacco, such as chewing tobacco
  • Alcohol use disorder
  • Diabetes
  • Chronic pancreatitis, hereditary pancreatitis, or family nonpolyposis colon cancer syndrome
  • Family or personal history of certain types of colon polyps or colon cancer
  • Family history of pancreatic cancer, especially in Ashkenazi Jews with BRCA2 gene, which is associated with breast cancer
  • High-fat diet
  • Obesity, which may also reduce your chance of survival from pancreatic cancer


Pancreatic cancer does not cause symptoms in its early stages. The cancer may grow for some time before it causes symptoms. When symptoms do appear, they may be very vague. In many cases, the cancer has spread outside the pancreas by the time it is discovered.

Symptoms will vary depending on the location and size of the tumor. Pancreatic cancer may cause:

  • Nausea
  • Loss of appetite
  • Unexplained weight loss
  • Pain—in the upper abdomen, sometimes spreading to the back (a result of the cancer growing and spreading)
  • Jaundice—yellowing of the skin and whites of the eyes, dark urine, tan stool, or stool that floats to the top of the bowl
  • Weakness, lightheadedness, chills, muscle spasms, diarrhea—especially if the cancer involves the islet cells that make insulin and other hormones


The doctor will ask about your symptoms and medical history. A physical exam will be done. The doctor may order blood and urine tests, as well as check for hidden blood in your stool.

Imaging tests evaluate the pancreas and surrounding structures:

  • Upper gastrointestinal (GI) series
  • CT scan
  • MRI scan
  • Ultrasound
  • Endoscopic retrograde cholangiopancreatography (ERCP)
  • Percutaneous transhepatic cholangiography (PTC)
  • Angiography

Your doctor may also want to take a biopsy—removal of a sample of pancreatic tissue for examination under a microscope

The physical exam combined with all of your test results, will help to determine the stage of cancer you have. Staging is used to guide your treatment plan. Like other cancers, pancreatic cancer is staged from I-IV. Stage I is a very localized cancer, while stage IV indicates a spread to other parts of the body.


Treatments for pancreatic cancer depends on the stage of the cancer. Treatments include:


To help reduce your chances of pancreatic cancer:

  • Talk to your doctor about how you can successfully quit smoking
  • Drink alcohol in moderation, which is a maximum of 2 drinks or less per day for men and a maximum of 1 drink per day for women
  • Lose weight or maintain a healthy weight
  • Eat a healthful diet
  • If possible, minimize exposure to cancer-causing agents, especially if you work in the petroleum or dry-cleaning industries
