Pancreatic cancer is often called a “silent killer” because its symptoms tend to be vague or nonspecific in the early stages, making it difficult to detect until the disease has progressed.
However, recognizing potential warning signs can help with early diagnosis and improve treatment outcomes. Here are 10 signs of pancreatic cancer that you should never ignore:

1. Jaundice (Yellowing of the Skin and Eyes)
- What It Is : Jaundice occurs when there is a buildup of bilirubin, a yellow pigment produced during the breakdown of red blood cells, due to blockage of the bile duct by a tumor.
- Signs to Watch For : Yellowing of the skin or eyes, dark urine, pale or clay-colored stools, and itching (pruritus).
- Why It Matters : Jaundice is one of the most common early symptoms of pancreatic cancer, particularly when the tumor is located in the head of the pancreas.
2. Abdominal Pain That Radiates to the Back
- What It Is : Pain in the upper abdomen that may spread to the back is a common symptom of pancreatic cancer, especially as the tumor grows and presses on nearby organs or nerves.
- Signs to Watch For : Persistent or worsening pain, often worse after eating or lying down, and relief when leaning forward.
- Why It Matters : This type of pain may indicate that the cancer is affecting the pancreas or surrounding structures.
3. Unexplained Weight Loss
- What It Is : Sudden, significant weight loss without trying can be a sign of pancreatic cancer. The cancer may interfere with digestion or appetite.
- Signs to Watch For : Losing 10 or more pounds over a short period (e.g., weeks or months) without changes in diet or exercise.
- Why It Matters : Weight loss is often one of the first noticeable symptoms of pancreatic cancer and should prompt further investigation.
4. Loss of Appetite
- What It Is : A reduced desire to eat or feeling full quickly after eating can occur due to hormonal changes caused by the cancer or pressure on the stomach.
- Signs to Watch For : Skipping meals, feeling full after a few bites, or general disinterest in food.
- Why It Matters : Loss of appetite contributes to weight loss and malnutrition, which can worsen overall health.
5. Nausea and Vomiting
- What It Is : Pancreatic tumors can block the digestive tract or press on the stomach, leading to nausea and vomiting.
- Signs to Watch For : Persistent nausea, especially after eating, or vomiting that doesn’t improve with standard treatments.
- Why It Matters : These symptoms may indicate that the tumor is interfering with normal digestive processes.
6. Changes in Stool (Diarrhea, Constipation, or Fatty Stools)
- What It Is : Pancreatic cancer can disrupt the production of digestive enzymes, leading to problems with fat absorption and bowel movements.
- Signs to Watch For : Pale, oily, or foul-smelling stools (steatorrhea), diarrhea, or constipation.
- Why It Matters : These changes suggest that the pancreas is not functioning properly, which could be due to cancer or other conditions.
7. New-Onset Diabetes or Poorly Controlled Diabetes
- What It Is : Pancreatic cancer can affect insulin production, leading to new-onset diabetes or difficulty managing existing diabetes.
- Signs to Watch For : Sudden spikes in blood sugar levels, increased thirst, frequent urination, or unexplained fatigue.
- Why It Matters : While diabetes is common, a new diagnosis or worsening control in someone over 50 should raise suspicion for pancreatic cancer.
8. Fatigue and Weakness
- What It Is : Extreme tiredness that doesn’t improve with rest can result from the body’s response to cancer or nutritional deficiencies caused by the disease.
- Signs to Watch For : Feeling exhausted all the time, even after adequate sleep, or an inability to perform daily tasks.
- Why It Matters : Fatigue is a nonspecific symptom but can signal advanced disease if accompanied by other warning signs.
9. Blood Clots (Deep Vein Thrombosis or Pulmonary Embolism)
- What It Is : Pancreatic cancer increases the risk of blood clots, which can form in the legs (deep vein thrombosis) or travel to the lungs (pulmonary embolism).
- Signs to Watch For : Swelling, redness, or pain in a leg; sudden shortness of breath; chest pain.
- Why It Matters : Blood clots can be life-threatening and may indicate an underlying cancer.
10. Enlarged Gallbladder or Liver
- What It Is : A growing tumor in the pancreas can block the bile duct, causing bile to back up and leading to gallbladder or liver enlargement.
- Signs to Watch For : A doctor may detect an enlarged gallbladder or liver during a physical exam or imaging tests.
- Why It Matters : These findings often point to a blockage in the bile duct, which could be caused by pancreatic cancer.
Conclusion
Pancreatic cancer is a serious condition, but being aware of its warning signs can make a difference in early detection and treatment. If you or a loved one experience jaundice, abdominal pain, unexplained weight loss, or other concerning symptoms, don’t delay seeking medical advice. While these signs can also be caused by less serious conditions, ruling out pancreatic cancer is crucial for your health.
