Pancreatic cancer begins in the tissues of your pancreas — an organ in your abdomen that lies behind the lower part of your stomach. Your pancreas releases enzymes that aid digestion and produces hormones that help manage your blood sugar.
Several types of growths can occur in the pancreas, including cancerous and noncancerous tumors. The most common type of cancer that forms in the pancreas is pancreatic ductal adenocarcinoma, which begins in the cells that line the ducts that carry digestive enzymes out of the pancreas.
Signs and symptoms of pancreatic cancer often don't occur until the disease is advanced. This means the disease rarely is detected at its early stages when it's most curable.
Pancreatic cancer symptoms can include:
Abdominal pain that radiates to your back
Loss of appetite or unintended weight loss
Yellowing of your skin and the whites of your eyes
New diagnosis of diabetes or existing diabetes that's becoming more difficult to control
Factors that can increase your risk of pancreatic cancer include:
Family history of genetic syndromes that can increase cancer risk, including a BRCA2 gene mutation, Lynch syndrome and familial atypical mole malignant melanoma syndrome
Family history of pancreatic cancer
Older age, as most people are diagnosed after 65
Reducing your risk
While some of these risk factors are out of your control, here are some lifestyle choices you can make to reduce your risk:
Stop smoking If you smoke, try to stop. Talk to your health care provider 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 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 reduce your risk of cancer.
