Pancreatic Cancer Awareness
Pancreatic cancer begins in the tissues of your pancreas – an organ in your abdomen that lies horizontally behind the lower part of your stomach. Your pancreas releases enzymes that aid digestion and hormones that help manage your blood sugar.
Pancreatic cancer typically spreads rapidly to nearby organs. It is seldom detected in its early stages. But for people with pancreatic cysts or a family history of pancreatic cancer, some screening steps might help detect a problem early one sign of pancreatic cancer is diabetes, especially when it occurs with weight loss, jaundice or pain in the upper abdomen that spreads to the back.
Treatment may include surgery, chemotherapy, radiation therapy or a combination of these.
Signs and symptoms of pancreatic cancer often don’t occur until the disease is advanced. They may include:
- Pain in the upper abdomen that radiates to your back
- Loss of appetite or unintended weight loss
- New-onset diabetes
- Blood clots
- Yellowing of your skin and the whites of your eyes (jaundice)
When to see a doctor
See your doctor if you experience unexplained weight loss or if you have persistent fatigue, abdominal pain, jaundice, or other signs and symptoms that bother you. Many conditions can cause these symptoms, so your doctor may check for these conditions as well as pancreatic cancer.
It’s not clear what causes pancreatic cancer in most cases. Doctors have identified factors, such as smoking, that increase your risk of developing the disease.
Understanding your pancreas
Your pancreas is about 6 inches (15 centimeters) long and looks something like a pear lying on its side. It releases (secretes) hormones, including insulin, to help your body process sugar in the foods you eat. And it produces digestive juices to help your body digest food.
How pancreatic cancer forms
Pancreatic cancer occurs when cells in your pancreas develop mutations in their DNA. These mutations cause cells to grow uncontrollably and to continue living after normal cells would die. These accumulating cells can form a tumor. Untreated pancreatic cancer spreads to nearby organs and blood vessels.
Most pancreatic cancer begins in the cells that line the ducts of the pancreas. This type of cancer is called pancreatic adenocarcinoma or pancreatic exocrine cancer. Rarely, cancer can form in the hormone-producing cells or the neuroendocrine cells of the pancreas. These types of cancer are called islet cell tumors, pancreatic endocrine cancer and pancreatic neuroendocrine tumors.
Factors that may increase your risk of pancreatic cancer include:
- Chronic inflammation of the pancreas (pancreatitis)
- Family history of genetic syndromes that can increase cancer risk, including a BRCA2 gene mutation, Lynch syndrome and familial atypical mole-malignant melanoma (FAMMM) syndrome
- Family history of pancreatic cancer
- Older age, as most people are diagnosed after age 65
A large study demonstrated that the combination of smoking, long-standing diabetes and a poor diet increases the risk of pancreatic cancer beyond the risk of any one of these factors alone.
As pancreatic cancer progresses, it can cause complications such as:
Weight loss. A number of factors may cause weight loss in people with pancreatic cancer. The cancer itself may cause weight loss. Nausea and vomiting caused by cancer treatments or a tumor pressing on your stomach may make it difficult to eat. Or your body may have difficulty processing nutrients from food because your pancreas isn’t making enough digestive juices.
Your doctor may recommend pancreatic enzyme supplements to aid in digestion. Try to maintain your weight by adding extra calories where you can and making mealtime as pleasant and relaxed as possible.
Jaundice. Pancreatic cancer that blocks the liver’s bile duct can cause jaundice. Signs include yellow skin and eyes, dark-colored urine, and pale-colored stools. Jaundice usually occurs without abdominal pain.
Your doctor may recommend that a plastic or metal tube (stent) be placed inside the bile duct to hold it open. This is done with the help of a procedure called endoscopic retrograde cholangiopancreatography (ERCP). During ERCP an endoscope is passed down your throat, through your stomach and into the upper part of your small intestine. A dye is then injected into the pancreatic and bile ducts through a small hollow tube (catheter) that’s passed through the endoscope. Finally, images are taken of the ducts.
Pain. A growing tumor may press on nerves in your abdomen, causing pain that can become severe. Pain medications can help you feel more comfortable. Radiation therapy might help stop tumor growth temporarily to give you some relief.
In severe cases, your doctor might recommend a procedure to inject alcohol into the nerves that control pain in your abdomen (celiac plexus block). This procedure stops the nerves from sending pain signals to your brain.
Bowel obstruction. Pancreatic cancer that grows into or presses on the first part of the small intestine (duodenum) can block the flow of digested food from your stomach into your intestines.
Your doctor may recommend a tube (stent) be placed in your small intestine to hold it open. Or surgery may be necessary to attach your stomach to a lower point in your intestines that isn’t blocked by cancer.
You may reduce your risk of pancreatic cancer if you:
Stop smoking. If you smoke, try to stop. Talk to your doctor about strategies to help you stop, including support groups, medications and nicotine replacement therapy. If you don’t smoke, don’t start.
Maintain a healthy weight. If you are at a healthy weight, work to maintain it. If you need to lose weight, aim for a slow, steady weight loss – 1 to 2 pounds (0.5 to 1 kilogram) a week. Combine daily exercise with a diet rich in vegetables, fruit and whole grains with smaller portions to help you lose weight.
Choose a healthy diet. A diet full of colorful fruits and vegetables and whole grains may help reduce your risk of cancer.
Consider meeting with a genetic counselor if you have a family history of pancreatic cancer. He or she can review your family health history with you and determine whether you might benefit from a genetic test to understand your risk of pancreatic cancer or other cancers.
If your doctor suspects pancreatic cancer, he or she may have you undergo one or more of the following tests:
Imaging tests that create pictures of your internal organs. These tests help your doctors visualize your internal organs, including the pancreas. Techniques used to diagnose pancreatic cancer include ultrasound, computerized tomography (CT) scans, magnetic resonance imaging (MRI) and, sometimes, positron emission tomography (PET) scans.
Using a scope to create ultrasound pictures of your pancreas. An endoscopic ultrasound (EUS) use an ultrasound device to make images of your pancreas from inside your abdomen. The device is passed through a thin, flexible tube (endoscope) down your esophagus and into your stomach in order to obtain the images.
Removing a tissue sample for testing (biopsy). A biopsy is a procedure to remove a small sample of tissue for examination under a microscope. Your doctor may obtain a sample of tissue from the pancreas (fine-needle aspiration). Or he or she may remove a sample during EUS, guiding special tools into the pancreas.
Blood test. Your doctor may test your blood for specific proteins (tumor markers) shed by pancreatic cancer cells. One tumor marker test used in pancreatic cancer is called CA19-9. But the test isn’t always reliable, and it isn’t clear how best to use the CA19-9 test results. Some doctors measure your levels before, during and after treatment.
If your doctor confirms a diagnosis of pancreatic cancer, he or she tries to determine the extent (stage) of the cancer. Using information from staging tests, your doctor assigns your pancreatic cancer a stage, which helps determine what treatments are most likely to benefit to you.
The stages of pancreatic cancer are indicated by Roman numerals ranging from 0 to IV. The lowest stages indicate that the cancer is confined to the pancreas. By stage IV, the cancer has spread to other parts of the body.
The cancer staging system continues to evolve and is becoming more complex as doctors improve cancer diagnosis and treatment. Your doctor uses your cancer stage to select the treatments that are right for you.
Don’t hesitate to ask your doctor about his or her experience with diagnosing pancreatic cancer. If you have any doubts, get a second opinion.
Treatment for pancreatic cancer depends on the stage and location of the cancer as well as on your overall health and personal preferences. For most people, the first goal of pancreatic cancer treatment is to eliminate the cancer, when possible. When that isn’t an option, the focus may be on improving your quality of life and preventing the cancer from growing or causing more harm.
Treatment may include surgery, radiation, chemotherapy or a combination of these. When pancreatic cancer is advanced and these treatments aren’t likely to offer a benefit, your doctor will offer symptom relief (palliative care) that makes you as comfortable as possible.
Operations used in people with pancreatic cancer include:
Surgery for tumors in pancreatic head. If your cancer is located in the head of the pancreas, you may consider an operation called a Whipple procedure (pancreaticoduodenectomy).
The Whipple procedure is technically difficult operation to remove the head of the pancreas, the first part of the small intestine (duodenum), the gallbladder and part of the bile duct. In some situations, part of the stomach and nearby lymph nodes may be removed as well. Your surgeon reconnects the remaining parts of your pancreas, stomach and intestines to allow you to digest food.
Surgery for tumors in the pancreatic body and tail. Surgery to remove the left side (body and tail) of the pancreas is called distal pancreatectomy. Your surgeon may also remove your spleen.
Surgery to remove the entire pancreas. In some people, the entire pancreas may need to be removed. This is called total pancreatectomy. You can live relatively normally without a pancreas but do need lifelong insulin and enzyme replacement.
Surgery for tumors affecting nearby blood vessels. Many people with advanced pancreatic cancer are not considered eligible for the Whipple procedure or other pancreatic surgeries if their tumors involve nearby blood vessels. At a very few medical centers in the United States, highly specialized and experienced surgeons will safely perform these operations with removal and reconstruction of parts of blood vessels in select patients.
Each of these surgeries carries the risk of bleeding and infection. After surgery some people experience nausea and vomiting if the stomach has difficulty emptying (delayed gastric emptying). Expect a long recovery after any of these procedures. You’ll spend several days in the hospital and then recover for several weeks at home.
Extensive research shows pancreatic cancer surgery tends to cause fewer complications when done by highly experienced surgeons at centers that do many of these operations. Don’t hesitate to ask about your surgeon’s and hospital’s experience with pancreatic cancer surgery. If you have any doubts, get a second opinion.
Chemotherapy uses drugs to help kill cancer cells. These drugs can be injected into a vein or taken orally. You may receive one chemotherapy drug or a combination of the.
Chemotherapy can also be combined with radiation therapy (chemoradiation). Chemoradiation is typically used to treat cancer that has spread beyond the pancreas, but only to nearby organs and not to distant regions of the body. At specialized medical centers, this combination may be used before surgery to help shrink the tumor. Sometimes it is used after surgery to reduce the risk that pancreatic cancer may recur.
In people with advanced pancreatic cancer, chemotherapy is often used to control cancer growth and prolong survival.
Radiation therapy uses high-energy beams, such as those made from X-rays and protons, to destroy cancer cells. You may receive radiation treatments before or after cancer surgery, often in combination with chemotherapy. Or your doctor may recommend a combination of radiation and chemotherapy treatments when your cancer can’t be treated surgically.
Radiation therapy usually comes from a machine that moves around you, directing radiation to specific points on your body (external beam radiation). In specialized medical centers, radiation therapy may be delivered during surgery (intraoperative radiation).
Radiation therapy traditionally uses X-rays to treat cancer. Some medical centers offer proton beam radiation therapy, which may be a treatment option for some people with advanced pancreatic cancer.
Clinical trials are studies to test new treatments, such as systemic therapy, and new approaches to surgery or radiation therapy. If the treatment being studied proves to be safer and more effective than are current treatments, it can become the new standard of care.
Clinical trials for pancreatic cancer might give you a chance to try new targeted therapy, chemotherapy drugs, immunotherapy treatments or vaccines.
Clinical trials can’t guarantee a cure, and they might have serious or unexpected side effects. On the other hand, cancer clinical trials are closely monitored to ensure they’re conducted as safely as possible. And they offer access to treatments that wouldn’t otherwise be available to you.
Talk to your doctor about what clinical trials might be appropriate for you.
Supportive (palliative) care
Palliative care is specialized medical care that focuses on providing relief from pain and other symptoms of a serious illness. Palliative care specialists work with you, your family and your other doctors to provide an extra layer of support that complements your ongoing care. Palliative care can be used while undergoing aggressive treatments, such as surgery, chemotherapy and radiation therapy.
When palliative care is used along with other appropriate treatments – even soon after the diagnosis – people with cancer may feel better and live longer.
Palliative care is provided by teams of doctors, nurses and other specially trained professionals. These teams aim to improve the quality of life for people with cancer and their families. Palliative care is not the same as hospice care or end-of-life care.
Some integrative and alternative medicine approaches may help with signs and symptoms you experience due to your cancer or cancer treatments.
Treatments to help you cope with distress
People with cancer frequently experience distress. Some research suggests distress is more common in people with pancreatic cancer than it is in people with other types of cancer.
If you’re distressed, you may have difficulty sleeping and find yourself constantly thinking about your cancer. You may feel angry or sad.
Discuss your feelings with your doctor. Specialists can help you sort through your feelings and help you devise strategies for coping. In some cases, medications may help.
Integrative medicine and alternative therapies may also help you cope with distress. Examples include:
- Art therapy
- Music therapy
- Relaxation exercises
Talk with your doctor if you’re interested in these treatment options.
Coping and support
Learning you have a life-threatening illness can be devastating. Some of the following suggestions may help:
Learn what you need to know about your cancer. Learn enough about your cancer to help you make decisions about your care. Ask your doctor about the details of your cancer and your treatment options. Ask about trusted sources of further information.
If you’re doing your own research, good places to start include the National Cancer Institute and the Pancreatic Cancer Action Network.
Assemble a support system. Ask your friends and family to form a support network for you. They may feel helpless and uncertain after your diagnosis. Helping you with simple tasks might give them comfort. And you might find relief in not having to worry about certain tasks. Think of things you want help with, such as meal preparation or getting to appointments.
Find someone to talk with. Although friends and family can be your best allies, in some cases they have difficulty coping with the shock of your diagnosis. In these cases, talking with a counselor, medical social worker, or a pastoral or religious counselor can be helpful. Ask your doctor for a referral.
Connect with other cancer survivors. You may find comfort in talking with other cancer survivors. Contact your local chapter of the American Cancer Society to find cancer support groups in your area. The Pancreatic Cancer Action Network can connect you with a pancreatic cancer survivor who can provide support by phone or email.
Consider hospice. Hospice care provides comfort and support to terminally ill people and their loved ones. It allows family and friends – with the aid of nurses, social workers and trained volunteers – to care for and comfort a loved one at home or in a hospice residence. Hospice care also provides emotional, social and spiritual support for people who are ill and those closest to them.
