In short
Most pancreatic cancers are not inherited. A smaller group runs in families because of a gene change passed from parent to child.
Smoking, long-standing diabetes, repeated pancreatitis and obesity raise the risk too. Of these, only smoking and weight are fully in your hands.
Anyone with pancreatic cancer should be offered a gene test. Healthy relatives with a strong family history may be offered one as well.
This post is about risk. For tests, surgery and chemotherapy once the cancer is found, see our pancreatic cancer treatment page.
Smoking is the clearest risk you can control. Long-standing diabetes, repeated pancreatitis, obesity and heavy drinking add to it.
No single cause explains the cancer in one person. Several risks usually pile up over many years, and many patients have none of them.
| Risk | Why it matters | What you can do |
|---|---|---|
| Smoking, including bidis and chewed tobacco | Strongest habit risk; it falls slowly after you quit | Stop now; ask us for help if it is hard |
| Diabetes | Long-standing diabetes adds risk. Diabetes that starts after 50, with weight loss, can be an early sign | Tell your doctor if sugar turns up suddenly with weight loss |
| Chronic or repeated pancreatitis | Years of inflammation damage the pancreas cells | Treat the cause: alcohol, gallstones or blocked ducts |
| Obesity | Linked to inflammation and insulin resistance | Steady weight loss with food and exercise |
| Heavy alcohol | Acts mostly by causing pancreatitis | Cut down or stop |
Diet plays a smaller part. Plenty of red and processed meat may add a little, but no food is proven to cause or prevent this cancer.
A small share of patients carry an inherited gene change. The signs are two or more close relatives with the cancer, or a diagnosis at a young age.
Close relatives means a parent, brother, sister or child. Think of the whole family, including other cancers, because some gene changes raise the risk of several cancers at once.
Having one relative with the cancer does not by itself mean you are at high risk. The risk rises with the number of close relatives and with how young they were.
The main groups are DNA-repair genes such as BRCA2, Lynch syndrome genes, and a few rarer syndromes. Each carries a different pattern of other cancers.
| Syndrome or gene | Other clues in the family | Why it matters |
|---|---|---|
| BRCA1, BRCA2, PALB2, ATM | Breast, ovarian or prostate cancer | Risk is raised; platinum chemotherapy and PARP inhibitors may help if cancer appears |
| Lynch syndrome (MLH1, MSH2, MSH6, PMS2) | Bowel and womb cancer at a young age | Risk is raised; immunotherapy may be an option |
| CDKN2A (familial melanoma) | Many moles, melanoma | Risk is clearly raised; skin checks are also needed |
| Peutz-Jeghers syndrome (STK11) | Dark spots on the lips, bowel polyps | Risk is raised from a young age |
| Hereditary pancreatitis (PRSS1) | Pancreatitis from childhood in the family | Risk is raised for life, so close follow-up is advised |
| Familial pancreatic cancer | Two or more close relatives with the cancer, and no known gene | Risk is raised even when no gene is found |
Rarer syndromes, such as familial polyposis and Li-Fraumeni syndrome, add a smaller risk. Most families with these syndromes are known for other cancers first.
Everyone with pancreatic cancer should be offered a germline test. A healthy relative is offered one when the family pattern points to a known gene.
A germline test reads the genes you were born with, using blood or saliva. It is different from the tumour test on the biopsy.
A counsellor also helps you decide whether to know the result. They help you plan how to tell the family, too. A gene panel is not cheap, so ask about the cost before you start.
Yes, but only a few people need it. Yearly MRI, sometimes with endoscopic ultrasound, is offered to carefully chosen high-risk people at expert centres.
There is no simple blood test or scan for the general public. Checking healthy people brings false alarms and needless operations, so it is kept for those whose risk is clearly high.
Screening is not a promise that the cancer will be found in time. We explain what it can and cannot do before you decide.
Stop tobacco, keep a healthy weight, treat diabetes well and avoid heavy drinking. These steps cannot remove an inherited risk, but they stop it from growing.
If your family tree worries you, read which tests come with a diagnosis, then bring your family details to a consultation.
Mostly not. A smaller group of patients carry a gene change passed down in the family. Two or more close relatives with the cancer, or a diagnosis at a young age, make this more likely.
Not necessarily. One affected relative raises the risk only a little. The risk is higher when several close relatives are affected or when they were diagnosed young.
Tobacco. Stopping smoking, including bidis and chewed tobacco, lowers the risk over the years. Keeping a healthy weight and treating diabetes also help.
Sometimes. Diabetes that starts suddenly after the age of 50, especially with weight loss, should be looked into. Most people with diabetes do not have this cancer.
A panel that includes BRCA1, BRCA2, PALB2, ATM, the Lynch syndrome genes, CDKN2A and STK11. It uses blood or saliva. A genetic counsellor helps choose the panel.
Only after a gene change is found in you. Then they can be tested for that one change. If no change is found, they follow the advice that fits the family history.
Not for the general public. Yearly MRI, sometimes with endoscopic ultrasound, is offered only to selected high-risk people at expert centres.
No. It raises the risk, but most carriers never develop pancreatic cancer. Knowing it lets you act early, stop tobacco and be checked if you qualify.
