1. Medical History and Physical Examination
The first step is usually a discussion about symptoms and general health.
A doctor may ask:
-
When did the symptoms begin?
-
Are they becoming more frequent or severe?
-
Has there been unexplained weight loss?
-
Is there a history of diabetes?
-
Has the person experienced jaundice?
-
Is there a family history of pancreatic or other related cancers?
-
Does the person smoke or have a history of chronic pancreatitis?
The doctor may also examine the abdomen, check for jaundice, and look for signs of fluid accumulation or other abnormalities.
These findings help determine whether additional testing is necessary.
2. Blood Tests
Blood tests can provide useful information about liver function, pancreatic function, blood glucose, and general health.
A doctor may request:
-
Liver function tests.
-
Bilirubin levels.
-
Blood glucose or HbA1c.
-
Complete blood count.
-
Kidney function tests.
-
Other tests depending on the patient's symptoms.
If a tumor blocks the bile duct, bilirubin and certain liver-related measurements may become elevated.
However, normal blood test results do not rule out pancreatic cancer.
3. CA 19-9 Tumor Marker
CA 19-9 is a substance that may be elevated in the blood of some people with pancreatic cancer.
Doctors sometimes use it to help assess a patient who is already being investigated for pancreatic disease or to monitor treatment response.
However, CA 19-9 has important limitations.
It may also be elevated in noncancerous conditions such as bile duct obstruction, pancreatitis, and certain liver disorders.
Some people with pancreatic cancer have normal CA 19-9 levels. In addition, a small proportion of people do not produce this marker at all.
For these reasons, CA 19-9 cannot reliably diagnose pancreatic cancer by itself and is not recommended as a general screening test for healthy people.
4. Abdominal Ultrasound
Ultrasound uses sound waves to create images of internal organs.
It may help identify bile duct enlargement, gallstones, liver abnormalities, or certain pancreatic masses.
However, the pancreas can be difficult to visualize because of its deep location and the presence of gas in the stomach and intestines.
An ultrasound that does not show a clear abnormality cannot always exclude pancreatic disease.
If the clinical findings remain concerning, doctors may recommend more detailed imaging.
5. CT Scan
A contrast-enhanced CT scan is one of the main imaging methods used to evaluate suspected pancreatic cancer.
It can provide detailed information about:
-
The location and size of a pancreatic mass.
-
Whether nearby blood vessels are involved.
-
Whether lymph nodes appear abnormal.
-
Whether the disease may have spread to the liver or other organs.
Specialized pancreatic CT protocols may provide better detail than a routine abdominal scan.
The results help doctors assess the extent of disease and determine whether surgery may be possible.
6. MRI and MRCP
Magnetic resonance imaging uses magnetic fields and radio waves to produce detailed images of internal structures.
A specialized technique called magnetic resonance cholangiopancreatography, or MRCP, can visualize the bile ducts and pancreatic ducts.
MRI and MRCP may be particularly useful when doctors need additional information about duct obstruction, cysts, or other pancreatic abnormalities.
They can also complement CT findings in selected cases.
7. Endoscopic Ultrasound
Endoscopic ultrasound, often called EUS, combines endoscopy with ultrasound imaging.
A thin, flexible instrument is passed through the mouth into the stomach and upper small intestine. From this position, an ultrasound probe can obtain detailed images of the pancreas.
If necessary, the doctor may use a fine needle to collect a tissue sample from a suspicious area.
This procedure can be particularly valuable when a small pancreatic lesion is difficult to evaluate using other imaging methods.
8. Biopsy
A biopsy involves collecting tissue or cells for examination under a microscope.
A pathologist can examine the sample to determine whether cancer cells are present and identify the type of tumor.
A biopsy is often needed before starting chemotherapy or other nonsurgical cancer treatments.
However, in selected patients with imaging findings strongly suggestive of resectable pancreatic cancer, a specialist team may recommend proceeding directly to surgery without a preoperative biopsy.
The decision depends on the clinical situation and treatment plan.
Understanding the Stages of Pancreatic Cancer
Once pancreatic cancer is diagnosed, doctors determine how far the disease has progressed.
Staging helps guide treatment decisions and provides information about the likely course of the illness.
The most widely used system is the TNM classification, which considers:
-
T: The size and extent of the primary tumor.
-
N: Whether nearby lymph nodes contain cancer.
-
M: Whether the cancer has spread to distant organs.
These findings are used to assign an overall stage.
Stage 0: Carcinoma in Situ
At this very early stage, abnormal cells are present in the lining of the pancreatic ducts but have not invaded deeper tissues.
This stage is sometimes described as a precancerous or noninvasive condition, depending on the specific diagnosis.
It is not the same as invasive pancreatic cancer.
Stage I: Localized Cancer
The tumor is confined to the pancreas and has not spread to distant organs.
Depending on its size and location, surgery may be possible.
Stage II: Larger Tumor or Nearby Lymph Node Involvement
At this stage, the tumor may be larger or may have spread to nearby lymph nodes.
Some tumors remain suitable for surgery, while others may require treatment before an operation.
Stage III: Locally Advanced Cancer
The cancer may involve major blood vessels or extensive nearby structures.
In many cases, immediate surgery is not possible.
Treatment may include chemotherapy, sometimes combined with radiation therapy, depending on the individual circumstances.
Stage IV: Metastatic Cancer
The cancer has spread to distant organs, commonly the liver, lungs, or lining of the abdomen.
Treatment generally focuses on controlling the disease, relieving symptoms, maintaining quality of life, and extending survival where possible.
It is important to understand that stage alone does not tell the entire story. Tumor biology, general health, treatment response, and other individual factors also influence outcomes.
Treatment Options for Pancreatic Cancer
Treatment depends on the type of cancer, its stage, its location, the patient's general health, and whether the tumor can be surgically removed.
A multidisciplinary team may include surgeons, medical oncologists, radiation oncologists, radiologists, pathologists, nutrition specialists, and palliative care professionals.
1. Surgery
Surgery offers the possibility of long-term disease control or cure for some people with localized pancreatic cancer.
The most common operation for tumors in the head of the pancreas is the Whipple procedure, also known as pancreaticoduodenectomy.
This complex operation usually involves removing:
-
The head of the pancreas.
-
The duodenum, or first part of the small intestine.
-
The gallbladder.
-
Part of the bile duct.
-
Sometimes part of the stomach, depending on the surgical technique.
The surgeon then reconnects the remaining digestive structures so that food and digestive fluids can pass through the body.
For tumors in the body or tail of the pancreas, a distal pancreatectomy may be performed. This operation removes the affected portion of the pancreas and often the spleen.
In selected cases, a total pancreatectomy may be necessary, although this is less common.
