Pancreatic Cancer: Symptoms, Causes, Stages, Treatment and more

Pancreatic cancer is a formidable and often devastating disease that arises in the pancreas, an organ located behind the stomach. It is characterized by its aggressive nature and a high mortality rate, primarily because it is often diagnosed at an advanced stage. Pancreatic cancer can develop silently, with few noticeable symptoms in its early stages, making early detection a significant challenge. As the disease progresses, it can cause symptoms such as abdominal pain, jaundice, unintended weight loss, and digestive problems. Treatment options for pancreatic cancer typically include surgery, chemotherapy, and radiation therapy, but the success of these interventions largely depends on the stage at which the cancer is diagnosed. Research into more effective treatments and early detection methods continues, offering hope for improving the prognosis for those affected by this challenging cancer.

Pancreatic Cancer Symptoms

Pancreatic cancer often doesn’t cause noticeable symptoms in its early stages, which can make it difficult to detect. However, as the disease progresses, the following symptoms may become apparent:

Jaundice: Yellowing of the skin and the whites of the eyes can occur when the cancer blocks the bile duct, which may cause a buildup of bilirubin in the body.

Abdominal pain: Dull aching pain in the upper abdomen or back is a common symptom, often located around the area of the pancreas.

Unexplained weight loss: Significant, unexplained weight loss can occur in pancreatic cancer due to a lack of appetite and the body’s increased energy expenditure.

Loss of appetite: Many people with pancreatic cancer experience a loss of appetite, leading to weight loss.

New-onset diabetes: Some individuals with pancreatic cancer develop diabetes, or their existing diabetes worsens. This can be a result of the tumor affecting insulin production.

Digestive problems: This can include diarrhea, indigestion, and difficulty in digesting fatty foods.

Changes in stool: Stools may become pale, greasy, and float in the toilet due to a lack of pancreatic enzymes needed for digestion.

Nausea and vomiting: These symptoms can occur as a result of digestive issues and the blockage of the bile duct.

Fatigue: General tiredness and weakness can be a symptom of pancreatic cancer.

Blood clots: In some cases, the development of blood clots, particularly in the legs, can be a sign of pancreatic cancer.

It’s important to note that these symptoms are non-specific and can be caused by various other medical conditions. If you or someone you know experiences persistent or worsening symptoms, especially those mentioned above, it’s essential to consult a healthcare professional for a proper evaluation and diagnosis. Early detection of pancreatic cancer can improve the chances of successful treatment.

Pancreatic Cancer Causes

Pancreatic cancer is a complex disease, and its exact causes are not always well-understood. However, there are several risk factors that have been associated with an increased likelihood of developing pancreatic cancer. Some of these risk factors and potential causes include:

Age: The risk of developing pancreatic cancer increases with age, and most cases occur in individuals over the age of 45.

Smoking: Cigarette smoking is one of the most significant risk factors for pancreatic cancer. Smokers are about 2-3 times more likely to develop the disease than non-smokers.

Family History: A family history of pancreatic cancer can increase an individual’s risk, especially if a first-degree relative (parent, sibling, or child) has had the disease. Certain hereditary genetic syndromes can also raise the risk.

Obesity: Being overweight or obese is associated with an increased risk of pancreatic cancer.

Diabetes: Long-standing diabetes is a known risk factor for pancreatic cancer. The relationship between the two is complex and not entirely understood.

Chronic Pancreatitis: Chronic inflammation of the pancreas is associated with an increased risk of pancreatic cancer, particularly in people who have had the condition for many years.

Diet: A diet high in red and processed meats and low in fruits and vegetables may be linked to a higher risk of pancreatic cancer. Diets high in saturated fats and low in fiber might also contribute to the risk.

Alcohol: Heavy alcohol consumption is a risk factor for chronic pancreatitis, which, in turn, is associated with an increased risk of pancreatic cancer.

Workplace Exposures: Some workplace exposures, such as certain chemicals or pesticides, may increase the risk of developing pancreatic cancer in certain occupational settings.

Race and Ethnicity: Pancreatic cancer rates are higher in some populations, such as African Americans and Ashkenazi Jews.

Gender: Men have a slightly higher risk of developing pancreatic cancer than women.

Pancreatic cancer diagnosis

Diagnosing pancreatic cancer typically involves a combination of medical history review, physical examination, and various diagnostic tests. Pancreatic cancer can be challenging to diagnose because it often does not cause noticeable symptoms in its early stages. When symptoms do appear, they are often non-specific and can be associated with other medical conditions. Here are the steps involved in diagnosing pancreatic cancer:

  1. Medical History and Physical Examination:
    • Your doctor will ask about your medical history, including any risk factors for pancreatic cancer (such as family history or smoking history).
    • They will perform a physical examination to check for any signs of jaundice (yellowing of the skin and eyes), abdominal pain, or palpable masses in the abdomen.
  2. Blood Tests:
    • Blood tests can help identify certain markers that may indicate pancreatic cancer, such as elevated levels of bilirubin, CA 19-9, and CEA. However, these markers are not specific to pancreatic cancer and can also be elevated in other conditions.
  3. Imaging Studies:
    • Various imaging tests can provide a better view of the pancreas and help detect tumors. These tests may include:
      • CT (computed tomography) scan: A detailed X-ray that can visualize the pancreas and nearby structures.
      • MRI (magnetic resonance imaging) scan: Provides detailed images of the pancreas.
      • Endoscopic ultrasound (EUS): Combines endoscopy and ultrasound to obtain high-resolution images of the pancreas.
      • ERCP (endoscopic retrograde cholangiopancreatography): Can be used to visualize the bile and pancreatic ducts and may also assist in obtaining tissue samples.
  4. Biopsy:
    • To confirm the presence of cancer, a tissue sample (biopsy) is usually required. This can be done through various methods:
      • Fine-needle aspiration (FNA): A thin needle is guided into the pancreas to collect a tissue sample.
      • Core biopsy: A larger tissue sample is obtained using a larger needle or during surgery.
      • Surgical biopsy: In some cases, a biopsy may be obtained during surgery to remove part or all of the pancreas.
  5. Staging:
    • Once pancreatic cancer is confirmed, staging is performed to determine the extent of the cancer and whether it has spread to other organs. Staging helps guide treatment decisions.

Pancreatic cancer stages

Pancreatic cancer is typically staged using the TNM (Tumor, Nodes, Metastasis) system, which describes the size and extent of the tumor (T), whether nearby lymph nodes are involved (N), and whether the cancer has spread to distant parts of the body (metastasis or M). The combination of these factors helps determine the stage of pancreatic cancer. The most commonly used staging system for pancreatic cancer is the American Joint Committee on Cancer (AJCC) staging system. Here are the stages of pancreatic cancer according to this system:

Stage 0 (Tis, N0, M0): This stage is known as carcinoma in situ, where abnormal cells are found in the lining of the pancreas ducts but have not invaded nearby tissues or spread to lymph nodes or distant sites.

Stage I (T1, N0, M0): In this stage, the cancer is confined to the pancreas and is usually a small tumor (T1) that has not spread to nearby lymph nodes (N0) or distant sites (M0).

Stage IIA (T2, N0, M0): The cancer has grown slightly larger (T2) but still has not spread to nearby lymph nodes (N0) or distant sites (M0).

Stage IIB (T3, N0, M0): The cancer has now invaded nearby structures, such as blood vessels (T3), but has not spread to lymph nodes (N0) or distant sites (M0).

Stage III (T4, N0, M0): The cancer has further advanced, possibly involving nearby blood vessels or organs (T4), but it has not spread to lymph nodes (N0) or distant sites (M0).

Stage IVA (any T, N1, M0): At this stage, the cancer can be any size (any T) and may have spread to nearby lymph nodes (N1) but has not metastasized to distant organs (M0).

Stage IVB (any T, any N, M1): This is the most advanced stage, where the cancer can be any size (any T), may or may not have spread to nearby lymph nodes (any N), and has metastasized to distant organs (M1).

Pancreatic cancer treatment

Pancreatic cancer treatment typically depends on the stage and location of the cancer, the patient’s overall health, and other individual factors. Treatment options may include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, and palliative care. Here’s an overview of the main treatment options for pancreatic cancer:


Surgical removal of the tumor offers the best chance for a cure if the cancer is localized and hasn’t spread to other organs. Surgical options include:

Whipple Procedure (Pancreaticoduodenectomy): This is the most common surgery for tumors in the head of the pancreas. It involves removing the head of the pancreas, part of the small intestine, the gallbladder, and sometimes part of the stomach and bile duct.

Distal Pancreatectomy: Used when the tumor is in the body or tail of the pancreas. It involves removing the body and tail of the pancreas and sometimes the spleen.

Total Pancreatectomy: Involves removing the entire pancreas, along with the spleen, part of the stomach, and other nearby tissues. It is used in specific cases.


Chemotherapy uses drugs to kill cancer cells or stop their growth. It is often used before or after surgery to shrink tumors or target remaining cancer cells. Gemcitabine and nab-paclitaxel or FOLFIRINOX are common chemotherapy regimens for pancreatic cancer.

Radiation Therapy

Radiation therapy uses high-energy rays to target and destroy cancer cells. It can be used before surgery to shrink tumors, after surgery to kill remaining cancer cells, or as palliative care to relieve symptoms.

Targeted Therapy

These drugs target specific molecules involved in cancer cell growth. Erlotinib (Tarceva) is an example of a targeted therapy used for pancreatic cancer.


Immunotherapy aims to boost the body’s immune system to fight cancer. Some immunotherapies, like checkpoint inhibitors, are being studied for pancreatic cancer treatment.

Clinical Trials

Many experimental treatments and drugs are tested in clinical trials. Patients may consider enrolling in clinical trials to access new and potentially more effective treatments.

Palliative Care

This specialized medical care focuses on providing relief from the symptoms and side effects of cancer. It can help improve the patient’s quality of life and manage pain and discomfort.

Pancreatic cancer prevention

Preventing pancreatic cancer is challenging because the exact causes of this cancer are not always clear. However, there are some strategies and lifestyle changes that may reduce the risk of developing pancreatic cancer. Keep in mind that these are general guidelines, and it’s essential to consult with a healthcare professional for personalized advice and early detection.

Don’t smoke: Smoking is a significant risk factor for pancreatic cancer. If you smoke, quitting is one of the most effective ways to reduce your risk.

Maintain a healthy weight: Being overweight or obese is linked to an increased risk of pancreatic cancer. Eat a balanced diet and engage in regular physical activity to achieve and maintain a healthy weight.

Eat a healthy diet: A diet high in fruits, vegetables, and whole grains while being low in red meat, processed meats, and saturated fats may help reduce the risk of pancreatic cancer.

Limit alcohol consumption: Excessive alcohol use is associated with a higher risk of developing pancreatic cancer. If you drink alcohol, do so in moderation.

Manage diabetes: There is a link between diabetes and pancreatic cancer. If you have diabetes, work with your healthcare provider to manage it effectively.

Chronic pancreatitis: If you have chronic pancreatitis, a condition causing long-term inflammation of the pancreas, work closely with your healthcare provider to manage it and minimize further damage.

Genetic counseling: Some individuals may have a higher risk of developing pancreatic cancer due to family history or genetic mutations. If you have a family history of pancreatic cancer or other risk factors, consider genetic counseling to assess your risk.

Aspirin and other medications: Some studies suggest that regular use of aspirin and certain medications may reduce the risk of pancreatic cancer. However, these medications come with potential side effects, so their use should be discussed with a healthcare professional.

Stay hydrated: There is some evidence to suggest that staying well-hydrated may help reduce the risk of pancreatic cancer.

Regular medical check-ups: Routine health check-ups can help detect early signs of pancreatic cancer or other health issues. If you have risk factors, make sure to discuss them with your healthcare provider.

The Bottom Line

The bottom line is that preventing pancreatic cancer involves making lifestyle choices such as not smoking, maintaining a healthy weight, eating a balanced diet, limiting alcohol consumption, managing diabetes, and staying hydrated. Additionally, it’s crucial to be aware of your family history and any genetic risk factors. Regular medical check-ups are essential for early detection and, ultimately, improving the chances of successful treatment.
