12 Signs and Symptoms of Pancreatic Cancer to Know

Pancreatic cancer can be difficult to recognize in its early stages because it often causes few noticeable symptoms at first. When symptoms do appear, they may resemble common digestive problems, making them easy to overlook.

The pancreas is an organ located behind the stomach. It plays important roles in digestion and blood-sugar regulation. Pancreatic cancer develops when abnormal cells in the pancreas begin growing uncontrollably. The most common type is pancreatic adenocarcinoma, while pancreatic neuroendocrine tumors are less common and can behave differently.

Knowing the signs and symptoms of pancreatic cancer can help you recognize changes that deserve medical attention. However, having one or more of these symptoms does not mean you have cancer. Many of them are much more commonly caused by other health conditions.

Here are 12 possible warning signs to know.

1. Yellowing of the Skin or Eyes

One of the more recognizable possible signs of pancreatic cancer is jaundice, which causes the skin and whites of the eyes to become yellow.

Jaundice happens when bilirubin, a yellow substance produced by the body, builds up in the bloodstream. A tumor located near the head of the pancreas can sometimes press on or block the common bile duct, preventing bile from flowing normally into the intestine.

Jaundice may occur along with other changes, including:

• Yellow skin or eyes
• Dark urine
• Pale or gray-colored stools
• Itchy skin

Jaundice has many causes besides pancreatic cancer, including gallstones, hepatitis, and other liver or bile-duct conditions. Nevertheless, new unexplained jaundice should be medically evaluated promptly.

2. Unexplained Weight Loss

Unintentional weight loss is another possible symptom of pancreatic cancer.

Some people may lose a significant amount of weight without intentionally changing their diet or exercise routine. Cancer can affect appetite, digestion, metabolism, and the body’s ability to process nutrients.

Weight loss can also occur because a person simply does not feel like eating.

However, unexplained weight loss is not specific to pancreatic cancer. Thyroid problems, digestive disorders, infections, stress, medications, and many other conditions can cause similar changes.

If you are losing weight without trying—particularly if the weight loss continues—talk with a healthcare professional.

3. Loss of Appetite

A noticeable decrease in appetite can sometimes occur with pancreatic cancer.

You may find that foods you previously enjoyed no longer appeal to you or that you simply do not feel hungry as often.

Loss of appetite can also occur with infections, medications, depression, digestive disorders, chronic illnesses, and other conditions.

The concern is greater when appetite loss is persistent or occurs alongside symptoms such as unexplained weight loss, abdominal pain, nausea, or jaundice.

4. Upper Abdominal Pain

Pain or discomfort in the upper abdomen is another possible symptom.

The pancreas is located deep inside the abdomen, behind the stomach. A tumor can affect surrounding tissues and organs or irritate nearby nerves, potentially causing abdominal discomfort.

The pain may be:

• Dull or aching
• Persistent
• Located in the upper abdomen
• Worse after eating in some cases
• Associated with back discomfort

Abdominal pain is extremely common and usually has causes other than pancreatic cancer. Indigestion, ulcers, gallstones, pancreatitis, and other gastrointestinal problems can produce similar symptoms.

Persistent or unexplained abdominal pain should be evaluated rather than self-diagnosed.

5. Back Pain

Pain that begins in the abdomen and extends toward the back can occur with pancreatic cancer.

The pancreas is positioned close to the spine and several major nerves. As a pancreatic tumor grows, it can affect nearby structures and contribute to back or abdominal pain.

However, back pain is one of the most common complaints in the general population and is usually caused by problems involving muscles, joints, discs, nerves, or other conditions.

Back pain becomes more concerning when it is persistent, unexplained, or occurs together with weight loss, jaundice, appetite changes, or abdominal pain.

6. Nausea and Vomiting

Pancreatic cancer can sometimes interfere with the normal movement of food through the digestive system.

If a tumor presses against part of the stomach or small intestine, it can contribute to nausea, vomiting, abdominal discomfort, and difficulty eating. These symptoms may become worse after meals.

But nausea and vomiting are much more commonly associated with other conditions, including stomach infections, food poisoning, medication side effects, migraines, pregnancy, and digestive disorders.

Repeated or persistent vomiting should be discussed with a healthcare professional, particularly if you cannot keep fluids down or are losing weight.

7. Changes in Stool

Changes in stool color or appearance can sometimes occur when pancreatic cancer interferes with the flow of bile or digestive enzymes.

Possible changes include:

• Pale or gray stools
• Greasy stools
• Floating stools
• Stools that are difficult to flush

Bile helps give stool its typical brown color. If bile cannot reach the intestine normally, stool may become unusually pale. Problems with pancreatic enzymes can also affect how fats are digested, potentially resulting in greasy or floating stools.

Changes in bowel movements have many possible causes, however. Persistent changes should be evaluated, especially when accompanied by abdominal pain, jaundice, or unexplained weight loss.

8. Dark Urine

Dark urine can sometimes be an early sign of jaundice.

When bilirubin accumulates in the bloodstream because bile flow is obstructed, more bilirubin can be eliminated through the urine, making it appear darker or brownish.

Dark urine can also occur because of dehydration, certain foods, medications, or other health conditions.

If your urine remains unusually dark despite adequate fluid intake—particularly if your eyes or skin are becoming yellow—contact a healthcare professional.

9. Persistent Itching

Itchy skin can occur when bilirubin and other substances associated with impaired bile flow accumulate in the body.

Some people with pancreatic cancer-related jaundice may therefore experience significant itching along with yellowing of the skin or eyes.

Itching alone is not a typical indication of pancreatic cancer. Dry skin, eczema, allergies, medications, and numerous other conditions can cause itching.

Unexplained, persistent itching accompanied by jaundice or changes in urine and stool color should be evaluated.

10. Fatigue or Unusual Weakness

Persistent fatigue is another possible symptom.

Someone may feel unusually tired or weak despite getting enough sleep and not having performed strenuous physical activity.

Fatigue is one of the least specific symptoms of cancer. Poor sleep, stress, anemia, infections, thyroid problems, nutritional deficiencies, medications, and many other conditions can cause it.

If unexplained fatigue continues for several weeks or interferes with normal activities, speak with a healthcare professional.

11. Gallbladder or Liver Enlargement

In some cases, pancreatic cancer can cause the gallbladder or liver to become enlarged.

A blockage of the bile duct can cause bile to build up in the gallbladder. A healthcare professional may sometimes detect enlargement during a physical examination or see it on imaging.

Pancreatic cancer can also spread to the liver, potentially causing it to enlarge.

This is not something you can reliably diagnose yourself by feeling your abdomen. If you notice a persistent lump or fullness beneath the ribs, have it evaluated by a healthcare professional.

12. Blood Clots

Some people with pancreatic cancer develop blood clots, and in certain cases a clot may be one of the first clues that something is wrong.

A deep vein thrombosis, or DVT, commonly occurs in a large vein in the leg. Possible symptoms include:

• Swelling in one leg
• Leg pain or tenderness
• Warmth
• Redness or discoloration

If part of a blood clot travels to the lungs, it can cause a pulmonary embolism. Symptoms can include sudden difficulty breathing and chest pain.

Most blood clots are caused by conditions other than pancreatic cancer. However, a suspected blood clot requires prompt medical evaluation.

Sudden shortness of breath, chest pain, fainting, or coughing up blood can indicate a potentially serious pulmonary embolism and requires emergency medical attention.

Can Pancreatic Cancer Cause Diabetes?

Changes in blood sugar can sometimes be associated with pancreatic cancer.

The pancreas contains cells that produce insulin, a hormone that helps regulate blood glucose. Pancreatic cancer can affect insulin production and may contribute to diabetes or changes in blood-sugar levels.

Symptoms of high blood sugar can include:

• Increased thirst
• Frequent urination
• Increased hunger
• Unexplained weight loss
• Fatigue

However, diabetes is common and has many causes. Most people with diabetes do not have pancreatic cancer.

A new or unexpected change in blood sugar should be discussed with a healthcare professional, particularly when it occurs with other unexplained symptoms.

Why Pancreatic Cancer Can Be Difficult to Detect Early

One of the biggest challenges with pancreatic cancer is that early disease may cause few or no noticeable symptoms.

The pancreas is located deep within the abdomen, and early tumors may not be easily detected during a routine physical examination. When symptoms do develop, they can resemble common conditions such as indigestion, pancreatitis, ulcers, or other digestive problems.

This does not mean that every digestive symptom should raise concerns about cancer. It simply explains why persistent or unusual changes deserve appropriate medical evaluation.

Who May Have a Higher Risk?

Certain factors can increase the likelihood of developing pancreatic cancer.

These can include:

• Cigarette smoking
• A family history of pancreatic cancer
• Certain inherited genetic conditions
• Certain hereditary cancer syndromes
• Chronic pancreatitis
• Some metabolic conditions
• Increasing age

Having a risk factor does not mean that you will develop pancreatic cancer. Likewise, people without obvious risk factors can still develop the disease.

If you have a strong family history of pancreatic or related cancers, discuss your risk with a healthcare professional. Genetic counseling may be appropriate for some people.

Is There a Routine Screening Test for Pancreatic Cancer?

For people at average risk who have no symptoms, major professional organizations do not currently recommend routine pancreatic cancer screening because no screening test has been shown to reduce deaths from the disease.

People with certain inherited conditions or a strong family history may be considered for specialized surveillance.

If you believe you have an unusually high risk, ask a healthcare professional whether genetic counseling or specialized monitoring may be appropriate.

How Is Pancreatic Cancer Diagnosed?

Symptoms alone cannot diagnose pancreatic cancer.

If a healthcare professional suspects a problem involving the pancreas, they may review your medical history, perform a physical examination, and order appropriate tests. Depending on the situation, these may include imaging studies, blood tests, or a biopsy.

Imaging tests can help doctors examine the pancreas and surrounding organs. Blood tests may provide additional information, although there is no single blood test that can independently confirm pancreatic cancer.

If an abnormal area is discovered, further testing may be needed to determine what it is and whether cancer is present.

When Should You See a Doctor?

Many symptoms associated with pancreatic cancer are common and usually have other explanations. Still, you should consider making a medical appointment if you develop symptoms that are:

• Persistent
• Unexplained
• Getting worse
• Occurring together with other unusual symptoms
• Interfering with eating or daily activities

Particular attention should be paid to new jaundice, unexplained weight loss, persistent abdominal or back pain, ongoing vomiting, significant appetite loss, or major changes in stool or urine.

The National Cancer Institute advises people with symptoms that persist for a couple of weeks to see a doctor so the cause can be investigated.

Seek Urgent Medical Care for Certain Symptoms

Some symptoms require urgent attention regardless of whether cancer is the cause.

Seek emergency medical care for:

• Sudden severe difficulty breathing
• Severe chest pain
• Fainting or loss of consciousness
• Vomiting significant amounts of blood
• Severe abdominal pain
• Signs of a serious allergic reaction
• Symptoms that could indicate a blood clot traveling to the lungs

Do not wait for an online article or symptom checker to determine the cause of a potentially serious symptom.

Frequently Asked Questions

What are the most common symptoms of pancreatic cancer?

Common symptoms can include jaundice, unexplained weight loss, appetite loss, abdominal or back pain, nausea and vomiting, fatigue, and changes in stool or urine.

What is often the first sign of pancreatic cancer?

There is no single first symptom for everyone. Some pancreatic cancers cause jaundice relatively early, particularly tumors in the head of the pancreas. Others may initially cause vague symptoms or no noticeable symptoms.

Can pancreatic cancer cause back pain?

Yes. Pancreatic cancer can cause abdominal or back pain, but back pain is extremely common and is usually caused by other conditions. Persistent unexplained back pain should be evaluated, especially if other symptoms are present.

Does pancreatic cancer always cause jaundice?

No. Jaundice is common in pancreatic cancer, particularly when a tumor blocks the bile duct, but cancers in other parts of the pancreas may not cause jaundice until later.

Can pancreatic cancer cause digestive problems?

Yes. Pancreatic cancer can be associated with nausea, vomiting, appetite loss, abdominal discomfort, and changes in stool. However, digestive symptoms have many more common causes.

Can pancreatic cancer be detected early?

Pancreatic cancer can be difficult to detect early because early tumors often cause few noticeable symptoms. There is also no routine screening recommendation for people at average risk without symptoms.

Final Thoughts

Understanding the signs and symptoms of pancreatic cancer can help you recognize changes that should not be ignored. Possible symptoms include jaundice, unexplained weight loss, appetite loss, abdominal pain, back pain, nausea, vomiting, stool changes, dark urine, persistent itching, fatigue, blood clots, and changes involving the liver or gallbladder.

However, these symptoms are not specific to pancreatic cancer. Many are much more commonly caused by other medical conditions. The important thing is to pay attention to symptoms that are persistent, unexplained, worsening, or occurring together.

If you develop new jaundice, unexplained weight loss, persistent abdominal or back pain, prolonged appetite loss, or other concerning changes, arrange an evaluation with a qualified healthcare professional. Early assessment can help identify the actual cause and ensure that appropriate treatment is started when necessary.
