Certain factors affect prognosis (chance
of recovery) and treatment options.
Pancreatic cancer is a type of cancer that forms in the tissues of the pancreas.
The pancreas is a
gland about 6 inches long that is
shaped like a thin pear lying on its side. The wider end of the pancreas is
called the head, the middle section is called the body, and the narrow end is
called the tail. The pancreas lies between the stomach and the spine.EnlargeAnatomy of the pancreas. The pancreas has three areas: the head, body, and tail. It is found in the abdomen near the stomach, intestines, and other organs.
The pancreas has two main jobs in the body:
to make juices
that help break down food into substances the body can use
to make hormones, such as insulin and glucagon, that help control blood sugar
levels and help the body use and store the energy it gets
from food
Smoking and health history can affect the risk of pancreatic cancer.
Pancreatic cancer is caused by certain changes to the way pancreatic cells function, especially how they grow and divide into new cells. A risk factor is anything that increases the chance of getting a disease. Some risk factors for pancreatic cancer, like smoking, can be changed. However, risk factors also include things people cannot change, like their genetics and their family history. Learning about risk factors for pancreatic cancer can help you make changes that might lower your risk of getting it.
There are many risk factors for pancreatic cancer, but many do not directly cause cancer. Instead, they increase the chance of DNA damage in cells that may lead to pancreatic cancer. Learn more about how cancer develops at What Is Cancer?
Having one or more of these risk factors does not mean that you will get pancreatic cancer. Many people with risk factors never develop pancreatic cancer, while others with no known risk factors do.
These symptoms may be caused by many conditions other than pancreatic cancer. It’s important to check with your doctor if you have any of these symptoms to find out the cause and begin treatment, if needed.
Pancreatic cancer is difficult to diagnose
early.
Pancreatic cancer is difficult to detect and diagnose for the
following reasons:
There aren’t any noticeable signs or symptoms in the early
stages of pancreatic
cancer.
The signs and symptoms of pancreatic cancer, when present, are like the
signs and symptoms of many other illnesses.
Tests that examine the pancreas are used to diagnose and stage pancreatic cancer.
Pancreatic cancer is usually diagnosed with tests and procedures
that make pictures of the pancreas and the area around it. The process used
to find out if cancer cells have spread within and around the pancreas is
called staging. Tests and procedures
to detect, diagnose, and stage pancreatic cancer are usually done at the same
time. To plan treatment, it is important to know the stage of
the disease and whether the pancreatic cancer can be removed by
surgery.
Blood chemistry study is a laboratory test in which a blood sample is checked to measure the amounts of certain substances, such as bilirubin, released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
Tumor marker test checks a sample of blood, urine, or tissue to measure the amounts of certain substances, such as CA 19-9 and carcinoembryonic antigen (CEA), made by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the body. These are called tumor markers.
MRI (magnetic
resonance imaging) uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
CT scan (CAT
scan) uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-D views of tissues and organs. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. A spiral or helical CTscan makes a series of very detailed pictures of areas inside the body using an x-ray machine that scans the body in a spiral path.
PET scan (positron
emission tomography scan) uses a small amount of radioactive sugar (also called glucose) that is injected into a vein. Then a scanner rotates around the body to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. A PET scan and CT scan may be done at the same time. This is called a PET-CT.
Abdominal ultrasound makes pictures of the inside of the abdomen. The ultrasound transducer is pressed against the skin of the abdomen and directs high-energy sound waves (ultrasound) into the abdomen. The sound waves bounce off the internal tissues and organs and make echoes. The transducer receives the echoes and sends them to a computer, which uses the echoes to make pictures called sonograms.
Endoscopic
ultrasound (EUS) is a procedure that uses an endoscope inserted into the body, usually through the mouth or rectum. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. A probe at the end of the endoscope is used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This procedure is also called endosonography.
Endoscopic
retrograde cholangiopancreatography (ERCP) is a procedure to x-ray the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Sometimes pancreatic cancer causes these ducts to narrow and block or slow the flow of bile, causing jaundice. An endoscope (a thin, lighted tube) is passed through the mouth, esophagus, and stomach into the first part of the small intestine. A catheter (a smaller tube) is then inserted through the endoscope into the pancreatic ducts. A dye is injected through the catheter into the ducts and an x-ray is taken. If the ducts are blocked by a tumor, a fine tube may be inserted into the duct to unblock it. This tube (or stent) may be left in place to keep the duct open. Tissue samples may also be taken.
Percutaneous
transhepatic cholangiography (PTC) is a procedure to x-ray the liver and bile ducts. A thin needle is inserted through the skin below the ribs and into the liver. Dye is injected into the liver or bile ducts and an x-ray is taken. If a blockage is found, a thin, flexible tube called a stent is sometimes left in the liver to drain bile into the small intestine or a collection bag outside the body. This test is done only if ERCP cannot be
done.
Laparoscopy is a surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. The laparoscope may have an ultrasound probe at the end in order to bounce high-energy sound waves off internal organs, such as the pancreas. This is called laparoscopic ultrasound. Other instruments may be inserted through the same or other incisions to perform procedures such as taking tissue samples from the pancreas or a sample of fluid from the abdomen to check for cancer.
Biopsy is the removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. There are several ways to do a biopsy for pancreatic cancer.
A fine needle or a core needle may be inserted into the pancreas during an x-ray or
ultrasound to remove cells. Tissue
may also be removed during a laparoscopy or surgery to remove the tumor.
Some people decide to get a second opinion.
You may want to get a second opinion to confirm your pancreatic cancer diagnosis and treatment plan. If you seek a second opinion, you will need to get medical test results and reports from the first doctor to share with the second doctor. The second doctor will review the pathology report, slides, and scans. They may agree with the first doctor, suggest changes or another treatment approach, or provide more information about your cancer.
To learn more about choosing a doctor and getting a second opinion, visit Finding Cancer Care. You can contact NCI’s Cancer Information Service via chat, email, or phone (both in English and Spanish) for help finding a doctor, hospital, or getting a second opinion. For questions you might want to ask at your appointments, visit Questions to Ask Your Doctor about Cancer.
Certain factors affect prognosis (chance
of recovery) and treatment options.
The prognosis and treatment options depend on:
whether the tumor can be removed by surgery
the stage
of the cancer (the size of the tumor and whether the cancer has spread outside
the pancreas to nearby tissues or lymph
nodes or to other places in the body)
the patient’s general
health
whether the cancer has just been diagnosed or has recurred (come back)
Pancreatic cancer can be controlled only if it is found before it
has spread, when it can be completely removed by surgery. If the cancer has spread,
palliative treatment can improve the patient's
quality of life by controlling the
symptoms and complications of this disease.
Stages of Pancreatic Cancer
Key Points
Cancer stage describes the extent of cancer in the body.
The following stages are used for pancreatic
cancer:
Stage 0 (carcinoma in situ)
Stage I (also called stage 1) pancreatic cancer
Stage II (also called stage 2) pancreatic cancer
Stage III (also called stage 3) pancreatic cancer
Stage IV (also called stage 4) pancreatic cancer
The following groups are used to plan treatment:
Resectable pancreatic cancer
Borderline resectable pancreatic cancer
Locally advanced pancreatic cancer
Metastatic pancreatic cancer
Recurrent pancreatic cancer
Cancer stage describes the extent of cancer in the body.
Cancer stage describes the extent of cancer in the body, such as the size of the tumor, whether it has spread, and how far it has spread from where it first formed. It is important to know the stage of the pancreatic cancer to plan the best treatment.
There are several staging systems for cancer that describe the extent of the cancer. Pancreatic cancer staging usually uses the TNM staging system. Your cancer may be described by this staging system in your pathology report. Based on the TNM results, a stage (I, II, III, or IV, also written as 1, 2, 3, or 4) is assigned to your cancer. When talking to you about your cancer, your doctor may describe it as one of these stages.
The information in this section is about staging for exocrine pancreatic cancer, the most common type of pancreatic cancer.
The following stages are used for pancreatic
cancer:
Stage 0 (carcinoma in situ)
EnlargeStage 0 pancreatic cancer. Abnormal cells are found in the lining of the pancreas. These abnormal cells may become cancer and spread into nearby normal tissue.
In stage 0, abnormal cells are found in the lining of the pancreas. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.
Stage I (also called stage 1) pancreatic cancer
EnlargeStage I pancreatic cancer. Cancer is found in the pancreas only. In stage IA, the tumor is 2 centimeters or smaller. In stage IB, the tumor is larger than 2 centimeters but not larger than 4 centimeters.
In stage I, cancer has formed and is
found in the pancreas only. Stage I is divided into
stages IA and IB, depending on the size of the tumor.
Stage IB: The tumor is larger than 2 centimeters but not larger than 4 centimeters.
Stage II (also called stage 2) pancreatic cancer
Stage II is divided into
stages IIA and IIB, depending on the size of the tumor and where the
cancer has spread.
Stage IIA: The tumor is larger than 4 centimeters.EnlargeStage IIA pancreatic cancer. The tumor is larger than 4 centimeters.
Stage IIB: The tumor is any size, and cancer has spread to 1 to 3 nearby lymph nodes.EnlargeStage IIB pancreatic cancer. The tumor is any size and cancer has spread to 1 to 3 nearby lymph nodes.
Stage III (also called stage 3) pancreatic cancer
EnlargeStage III pancreatic cancer. The tumor is any size and cancer has spread to (a) 4 or more nearby lymph nodes; or (b) the major blood vessels near the pancreas. These include the portal vein, common hepatic artery, celiac axis (trunk), and superior mesenteric artery.
In stage III, the tumor is any size, and cancer has spread to:
EnlargeStage IV pancreatic cancer. The tumor is any size and cancer has spread to other parts of the body, such as the lung, liver, or peritoneal cavity (the body cavity that contains most of the organs in the abdomen).
In stage IV, the tumor is any size, and cancer has spread to other parts of the body, such as the liver, lung, or peritoneal cavity (the body cavity that contains most of the organs in the abdomen).
Stage IV pancreatic cancer is also called metastatic pancreatic cancer. Metastatic cancer happens when cancer cells travel through the lymphatic system or blood and form tumors in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if pancreatic cancer spreads to the liver, the cancer cells in the liver are actually pancreatic cancer cells. The disease is called metastatic pancreatic cancer, not liver cancer. Learn more in Metastatic Cancer: When Cancer Spreads.
The following groups are used to plan treatment:
Resectable pancreatic cancer
Resectable pancreatic cancer can be removed by surgery because it has not grown into major blood vessels near the tumor.
Borderline resectable pancreatic cancer
Borderline resectable pancreatic cancer has grown into a major blood vessel or nearby tissue or organs. It may be possible to remove the tumor, but there is a high risk that all of the cancer cells will not be removed with surgery.
Locally advanced pancreatic cancer
Locally advanced pancreatic cancer has grown into or close to nearby lymph nodes or blood vessels, so surgery cannot completely remove the cancer.
Metastatic pancreatic cancer
Metastatic pancreatic cancer has spread to other organs, so surgery cannot completely remove the cancer.
Recurrent pancreatic cancer
Recurrent pancreatic cancer is cancer that has recurred
(come back) after it has been treated. The cancer may come
back in the pancreas or in other
parts of the body. Tests will be done to help determine where the cancer has returned in your body. The type of treatment for recurrent pancreatic cancer will depend on where it has come back.
There are different types of treatment for patients with
pancreatic cancer.
The following types of treatment are used:
Surgery
Radiation therapy
Chemotherapy
Chemoradiation therapy
Targeted therapy
There are treatments for pain caused by pancreatic
cancer.
Patients with pancreatic cancer have special nutritional
needs.
New types of treatment are being tested in clinical trials.
Treatment for pancreatic cancer may cause side effects.
Follow-up care may be needed.
There are different types of treatment for patients with
pancreatic cancer.
Different types of treatments are available for people with pancreatic cancer. You and your cancer care team will work together to decide your treatment plan, which may include more than one type of treatment. Many factors will be considered, such as the stage of the cancer, your overall health, and your preferences. Your plan will include information about your cancer, the goals of treatment, your treatment options and the possible side effects, and the expected length of treatment.
Talking with your cancer care team before treatment begins about what to expect will be helpful. You’ll want to learn what you need to do before treatment begins, how you’ll feel while going through it, and what kind of help you will need. To learn more, visit Questions to Ask Your Doctor about Treatment.
The following types of treatment are used:
Surgery
One of the following types of surgery may be used to take out the
tumor:
Total
pancreatectomy is surgery to remove the whole pancreas, part
of the stomach, part of the small
intestine, the common bile
duct, the gallbladder, the spleen, and nearby lymph nodes.
Distal pancreatectomy is surgery to remove the body and the tail of the
pancreas. The spleen may also be removed if cancer has spread to the spleen.
Biliary bypass: If cancer is blocking the bile duct
and bile is building up in the
gallbladder, a biliary bypass may be done. During this operation, the doctor
will cut the gallbladder or bile duct in the area before the blockage and sew it to the small intestine to
create a new pathway around the blocked area.
Endoscopicstent placement: If the tumor is blocking the
bile duct, surgery may be done to put in a stent (a thin tube) to drain bile
that has built up in the area. The doctor may place the stent through a
catheter that drains the bile into a bag on the outside
of the body, or the stent may go around the blocked area and drain the bile into
the small intestine.
Gastric bypass:
If the tumor is blocking the flow of food from the stomach, the stomach may be
sewn directly to the small intestine so the patient can continue to eat
normally.
Radiation therapy
Radiation
therapy uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. Pancreatic cancer is sometimes treated with external beam radiation therapy. This type of radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer.
Chemotherapy (also called chemo) uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
Chemotherapy for pancreatic cancer is usually systemic, meaning it is injected into a vein or given by mouth. When given this way, the drugs enter the bloodstream to reach cancer cells throughout the body.
Chemotherapy drugs used to treat pancreatic cancer may include:
Chemoradiation therapy combines chemotherapy and radiation therapy to increase the effects of both.
Targeted therapy
Targeted therapy uses drugs or other substances to identify and attack specific cancer cells.
Erlotinib is a targeted therapy drug used to treat pancreatic cancer.
There are treatments for pain caused by pancreatic
cancer.
Pain can occur when the tumor presses on nerves or other organs
near the pancreas. When pain medicine is not enough, there are treatments that
act on nerves in the abdomen to
relieve the pain. The doctor may inject medicine into the area around affected
nerves or may cut the nerves to block the feeling of pain. Radiation therapy
with or without chemotherapy can also help relieve pain by shrinking the tumor.
Learn more about Cancer Pain.
Patients with pancreatic cancer have special nutritional
needs.
Surgery to remove the pancreas may affect its ability to make pancreatic enzymes that help to
digest food. As a result, patients may have problems digesting food and
absorbing nutrients into the body. To prevent malnutrition, the doctor may prescribe medicines
that replace these enzymes.
New types of treatment are being tested in clinical trials.
For some people, joining a clinical trial may be an option. There are different types of clinical trials for people with cancer. For example, a treatment trial tests new treatments or new ways of using current treatments. Supportive care and palliative care trials look at ways to improve quality of life, especially for those who have side effects from cancer and its treatment.
You can use the clinical trial search to find NCI-supported cancer clinical trials accepting participants. The search allows you to filter trials based on the type of cancer, your age, and where the trials are being done. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.
As you go through treatment, you will have follow-up tests or check-ups. Some tests that were done to diagnose or stage the cancer may be repeated to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back).

Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.
PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government’s center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.
Purpose of This Summary
This PDQ cancer information summary has current information about the treatment of adult pancreatic cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.
Reviewers and Updates
Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change.
The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.
Clinical Trial Information
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
