The doctor may ask when the symptoms began, whether weight has changed, whether appetite has declined and whether there is a family history of pancreatic cancer or certain inherited conditions. They may also review previous blood tests and medication use.
Depending on the findings, the next steps could include blood tests, imaging or referral to a specialist. The choice of tests depends on the person's individual circumstances. There is no single blood test that can reliably diagnose pancreatic cancer in everyone.
The relationship between diabetes and pancreatic cancer also works in the other direction: pancreatic cancer may sometimes lead to new diabetes, but existing diabetes is also associated with an increased risk of pancreatic cancer. These are related observations, not a guarantee that one condition will lead to the other.
People who already have diabetes should not assume that every change in blood sugar signals cancer. Blood glucose can fluctuate because of diet, illness, stress, medication changes and many other factors. If readings become unexpectedly difficult to control, or if new symptoms appear, discussing the pattern with a clinician is sensible.
It is equally important to avoid blaming people for developing diabetes. The condition is influenced by multiple biological and environmental factors. Lifestyle choices can affect risk, but they do not explain every case.
The wider message is that new-onset diabetes accompanied by unexplained weight loss or abdominal symptoms deserves thoughtful medical review. It is not a reason to panic, but it is a reason to make sure the changes are properly understood.

Chapter 4: Who May Have a Higher Risk, and Can the Disease Be Prevented?
Pancreatic cancer can affect people with different lifestyles and medical histories. Some individuals develop the disease despite having no obvious risk factors, while others may have several factors that increase their likelihood of developing it.
Understanding these factors can help people make informed decisions and discuss their personal history with a doctor.
Age
The risk of pancreatic cancer generally increases with age. Many people diagnosed with the disease are older adults, although younger people can also develop it. Age is not something that can be changed, but it is an important part of a person's overall medical history.
Smoking
Tobacco use is one of the most important modifiable risk factors. Chemicals in tobacco smoke can damage cells and contribute to changes that may lead to cancer.
People who smoke have a higher risk of pancreatic cancer than people who have never smoked. Quitting is beneficial even after many years of tobacco use. It can improve health in numerous ways and reduce the risk of several serious diseases.
Excess body weight
Obesity is associated with an increased risk of pancreatic cancer. Maintaining a healthy weight through balanced nutrition and regular physical activity may help reduce overall health risks.
This should not be interpreted as blaming people who develop cancer. Body weight is influenced by genetics, medical conditions, medication, environment and many other factors. Cancer can occur in people of every body size.
Chronic pancreatitis
Pancreatitis is inflammation of the pancreas. When inflammation continues over a long period, it can cause lasting damage to pancreatic tissue. Chronic pancreatitis is associated with an increased risk of pancreatic cancer.
People with a history of repeated or long-term pancreatic inflammation should discuss appropriate follow-up with their healthcare team.
Family history and inherited conditions
A family history of pancreatic cancer may increase risk, particularly when multiple close relatives have been affected. Certain inherited genetic changes and syndromes can also raise the likelihood of developing the disease.
People with a strong family history may benefit from speaking with a genetic counsellor or specialist. The healthcare team can assess whether genetic testing or a specialist surveillance programme is appropriate.
Can pancreatic cancer be prevented?
There is no guaranteed way to prevent pancreatic cancer. Some risk factors cannot be changed, and many cases occur in people without a clear family history or known inherited condition.
Nevertheless, certain practical steps can support general health and may lower some risks:
-
Avoid smoking and seek support to quit if needed.
-
Maintain a healthy weight where possible.
-
Eat a balanced diet with a variety of vegetables, fruit, whole grains and other nutritious foods.
-
Stay physically active according to personal ability.
-
Limit heavy alcohol consumption.
-
Seek medical care for persistent digestive symptoms or unexplained changes in health.
-
Discuss a strong family history of pancreatic cancer with a healthcare professional.
These steps do not guarantee protection. Someone who follows every healthy habit can still develop cancer, while someone with several risk factors may never develop it.
