Pancreatic cancer

Expert content reviewers:


Pancreatic cancer is cancer that starts in any part of the pancreas. About 75% of pancreatic cancers are found in the head of the pancreas.

Pancreatic cancer can spread to nearby lymph nodes and to the lining of the abdomen (peritoneum). Cancer cells may also travel through the bloodstream to other parts of the body, such as the liver.

Your guide to best cancer care

A lot can happen in a hurry when you’re diagnosed with cancer. The guide to best cancer care for pancreatic cancer can help you make sense of what should happen.

It will help you with what questions to ask your health professionals to make sure you receive the best care at every step.

Main types of pancreatic cancer

There are two main groups of pancreatic cancer:

  • Exocrine tumours – these make up more than 95% of pancreatic cancers. The most common type is called adenocarcinoma, and it starts in the exocrine cells lining the pancreatic duct. Less common types include adenosquamous carcinoma, acinar cell carcinoma, squamous cell carcinoma and undifferentiated carcinoma.
  • Pancreatic neuroendocrine tumours (NETs) – about 5% of cancers in the pancreas are pancreatic NETs. These start in the endocrine cells. Learn more about how pancreatic NETs are diagnosed and treated.

How common is pancreatic cancer?

About 4500 Australians are diagnosed with pancreatic cancer each year. More than 80% are over the age of 60. Pancreatic cancer was estimated to be the eighth most common cancer in Australia in 2023.

Pancreatic cancer affects men and women at about the same rate.

Symptoms

Early-stage pancreatic cancer rarely causes obvious symptoms. Symptoms may not appear until the cancer is large enough to affect nearby organs or has spread.

The first symptom of pancreatic cancer is often jaundice. Signs of jaundice may include yellowish skin and eyes, dark urine, pale bowel motions and itchy skin.

Jaundice is caused by the build-up of bilirubin, a dark yellow-brown substance found in bile. Bilirubin can build up if pancreatic cancer blocks the common bile duct.

Other common symptoms of pancreatic cancer include:

  • appetite loss
  • nausea with or without vomiting
  • unexplained weight loss
  • pain in the upper abdomen, side or back, which may cause you to wake up at night
  • changed bowel motions – including diarrhoea, severe constipation, or pale, oily, foul-smelling stools (poo) that are difficult to flush away
  • bloating and passing wind and burping more than usual
  • newly diagnosed type two diabetes
  • fatigue.

These symptoms can also occur in many other conditions and do not necessarily mean that you have cancer. If you are worried or have ongoing symptoms, speak with your general practitioner (GP).

“I went to the doctor because I was itchy and had constant diarrhoea. My GP initially thought it was gallstones and sent me for routine tests. After the CT scan I went into hospital for a laparoscopy and then had a biopsy, which confirmed I had cancer.” Jan

Risk factors

The causes of pancreatic cancer are not known, but research has shown that people with certain risk factors are more likely to develop pancreatic cancer, including:

  • smoking tobacco (smokers are about twice as likely to develop pancreatic cancer as non-smokers)
  • obesity
  • ageing
  • long-term diabetes (but diabetes can also be caused by the pancreatic cancer)
  • long-term pancreatitis (inflammation of the pancreas)
  • certain types of cysts in the pancreatic duct known as intraductal papillary mucinous neoplasms (IPMNs) – these should be assessed by an appropriate specialist
  • stomach infections caused by the Helicobacter pylori bacteria (which can also cause stomach ulcers)
  • family history and inherited conditions
  • workplace exposure to certain pesticides, dyes or chemicals.

Having risk factors does not mean you will definitely get cancer, but talk to your doctor if you are concerned. Some people with pancreatic cancer have no known risk factors.

Does pancreatic cancer run in families?

Most people diagnosed with pancreatic cancer do not have a family history of the disease.

Only about 5–10% of people who develop pancreatic cancer have inherited a faulty gene that increases the risk of developing pancreatic cancer.

You may have inherited a faulty gene linked to pancreatic cancer if: 

  • two or more of your close family members (such as a parent or sibling) have had pancreatic cancer
  • there is a family history of a genetic condition, such as Peutz-Jeghers syndrome, the familial breast cancer genes (BRCA1 and BRCA2), familial atypical multiple mole melanoma (FAMMM) syndrome, Lynch syndrome and hereditary pancreatitis.

Genetic testing aims to find inherited faulty genes that may increase a person’s risk of developing some cancers. People with a strong family history of cancer can go to a family cancer clinic for genetic counselling.

Health professionals

Your GP will arrange the first tests to assess your symptoms. If these tests do not rule out cancer, you will usually be referred to a specialist, such as a gastroenterologist or surgeon, who will arrange further tests.

If pancreatic cancer is diagnosed, the specialist will consider treatment options. Often these will be discussed with other health professionals at what is known as a multidisciplinary team (MDT) meeting.

During and after treatment, you will see a range of health professionals who specialise in different aspects of your care, including a pancreatic or HPB (hepato-pancreatobiliary) surgeon, endocrinologist, radiologist and dietician, among others.
