Pancreatic Carcinoma
What is Pancreatic Carcinoma?
Pancreatic carcinoma is a type of cancer that develops in the tissues of the pancreas. The pancreas is an organ behind your stomach that helps digest food and regulate blood sugar. Most pancreatic cancers, about 95%, are adenocarcinomas that start in the cells lining the pancreatic ducts.
This cancer grows quickly and often spreads before symptoms appear. It remains one of the most challenging cancers to detect early. The pancreas sits deep in your abdomen, making tumors difficult to feel during physical exams.
Early detection greatly improves outcomes, yet most cases are found in later stages. Understanding your risk factors and monitoring relevant biomarkers can help catch changes sooner. Regular blood testing provides valuable data about pancreatic function over time.
Symptoms
- Yellowing of the skin and eyes, also called jaundice
- Dark urine and light-colored or greasy stools
- Pain in the upper abdomen that may radiate to the back
- Loss of appetite and unintended weight loss
- Nausea and vomiting
- New onset diabetes or worsening blood sugar control
- Fatigue and weakness
- Blood clots in the legs or lungs
- Enlarged liver or gallbladder
Many people have no symptoms in the early stages of pancreatic carcinoma. Symptoms typically appear only after the tumor grows large enough to affect nearby organs or block ducts. This is why routine monitoring of pancreatic markers can be valuable for those at higher risk.

Causes and risk factors
The exact cause of pancreatic carcinoma is not fully understood, but certain genetic mutations trigger abnormal cell growth. Smoking is the most significant preventable risk factor, doubling your cancer risk. Age plays a major role, with most cases occurring after age 65. Family history matters, as 10% of cases have a hereditary component. Chronic pancreatitis, or long-term inflammation of the pancreas, increases risk substantially.
Diabetes, obesity, and metabolic syndrome all raise pancreatic cancer risk. A diet high in red meat, processed foods, and saturated fat may contribute. Heavy alcohol use and exposure to certain workplace chemicals also increase risk. African Americans have higher rates than other ethnic groups. Men develop pancreatic cancer more often than women, though rates are converging.
How it's diagnosed
Diagnosing pancreatic carcinoma involves imaging tests like CT scans, MRI, and endoscopic ultrasound to visualize the pancreas. A biopsy confirms the diagnosis by examining tissue cells under a microscope. Blood tests support diagnosis by measuring enzymes and markers related to pancreatic function. Amylase levels may be elevated when a tumor blocks pancreatic ducts, though this marker is not highly sensitive for cancer detection.
Rite Aid offers add-on testing for pancreatic markers including serum amylase through our blood testing service. While blood tests alone cannot diagnose pancreatic cancer, tracking these markers over time can reveal changes that warrant further investigation. If you have concerning symptoms or risk factors, getting tested at one of our 2,000 Quest Diagnostics locations provides important baseline data.
Treatment options
- Surgery to remove the tumor, possible only if cancer has not spread
- Chemotherapy to kill cancer cells throughout the body
- Radiation therapy to shrink tumors and relieve symptoms
- Targeted therapy drugs that attack specific cancer cell features
- Immunotherapy to help your immune system fight cancer
- Pain management through medications and nerve blocks
- Nutritional support including pancreatic enzyme supplements
- Managing diabetes that develops due to reduced pancreatic function
- Palliative care to improve quality of life at any stage

Frequently asked questions
The 5-year survival rate for pancreatic cancer is about 12% overall, but varies greatly by stage at diagnosis. When caught before spreading beyond the pancreas, the 5-year survival rate rises to about 44%. Unfortunately, only about 13% of cases are found at this early stage. Treatment advances continue to improve outcomes, especially for those diagnosed early.
Blood tests cannot definitively diagnose pancreatic cancer, but they provide supporting evidence. Serum amylase may be elevated when tumors block pancreatic ducts, though levels are often normal in early cancer. Tracking pancreatic markers over time can reveal changes that prompt further investigation. Imaging tests and biopsy remain necessary for definitive diagnosis.
People over age 65 face the highest risk, as most cases occur in this age group. Smokers have twice the risk of non-smokers. Those with family history of pancreatic cancer, chronic pancreatitis, or hereditary cancer syndromes also face elevated risk. Obesity, diabetes, and heavy alcohol use further increase chances of developing this cancer.
Early pancreatic cancer often causes no symptoms, which makes detection difficult. The earliest signs may include vague upper abdominal discomfort, unexplained weight loss, or new diabetes that is hard to control. Some people notice changes in stool color or consistency. If you have multiple risk factors, regular monitoring of pancreatic markers can help catch changes sooner.
About 10% of pancreatic cancers have a hereditary component linked to genetic mutations. Having one first-degree relative with pancreatic cancer doubles your risk. Having two or more affected relatives increases risk significantly. Genetic syndromes like BRCA2 mutations, Lynch syndrome, and familial pancreatitis all raise pancreatic cancer risk.
Smoking is the leading preventable risk factor for pancreatic carcinoma. Smokers are twice as likely to develop pancreatic cancer compared to those who have never smoked. The risk decreases after quitting but remains elevated for many years. About 25% of pancreatic cancers are attributed to cigarette smoking.
While no lifestyle change guarantees prevention, certain habits reduce risk. Maintaining a healthy weight lowers pancreatic cancer risk. Eating plenty of vegetables, fruits, and whole grains may offer protection. Limiting red and processed meats, avoiding tobacco, and moderating alcohol all help. Regular physical activity supports healthy metabolism and reduces inflammation.
Diabetes increases pancreatic cancer risk, especially in those with long-standing disease. Interestingly, pancreatic cancer can also cause new-onset diabetes, as tumors damage insulin-producing cells. Sudden diabetes in people over 50 with no family history sometimes signals underlying pancreatic cancer. Both conditions share risk factors like obesity and inflammation.
Testing frequency depends on your specific risk level and family history. People with hereditary cancer syndromes may need annual imaging and testing. Those with multiple risk factors should discuss monitoring schedules with their doctor. Regular blood tests that track pancreatic function provide baseline data that can reveal changes over time.
Elevated serum amylase can indicate pancreatic duct obstruction caused by a tumor. However, amylase levels are often normal or only slightly elevated in pancreatic cancer, making this a non-sensitive marker. Elevated amylase more commonly signals acute pancreatitis or other digestive issues. When elevated amylase occurs with other symptoms like jaundice or weight loss, further investigation is needed.
