Pancreatic cancer often causes no symptoms early on, and when they appear they are usually vague, which is why the disease is often diagnosed late. Typical warning signs involve changes in digestion, weight, energy, and the color of the skin, eyes, urine, or stool.

Main physical symptoms

  • Abdominal or back pain : Dull or persistent pain in the upper belly that may spread through to the back, often worse when lying down or after eating.
  • Unintentional weight loss and appetite loss : Losing weight without trying, feeling full quickly, or having little interest in food.
  • Jaundice : Yellowing of the whites of the eyes and skin, often with dark urine, pale or clay-colored stools, and sometimes very itchy skin.
  • Digestive changes : Nausea, vomiting, gas, bloating, indigestion, or stools that are greasy/oily, foul-smelling, or that float (steatorrhea) because fat is not being digested properly.

Energy, metabolism, and general health

  • Extreme tiredness (fatigue) : Ongoing, unexplained low energy is common as the cancer advances.
  • New or worsening diabetes : Some people develop diabetes for the first time with no clear cause; others find existing diabetes suddenly becomes harder to control.
  • Fever or feeling unwell : Occasional low-grade fevers, or feeling hot, cold, or shivery.

Other possible warning signs

  • Blood clots : Swelling, pain, redness, or warmth in an arm or leg can signal a clot (deep vein thrombosis), which can be associated with pancreatic cancer.
  • Bloating and abdominal swelling : Fluid buildup in the abdomen (ascites) can cause visible swelling and a feeling of tightness or fullness.

When to seek medical help

  • See a doctor as soon as possible if you have jaundice, suddenly develop diabetes without obvious reason, or notice ongoing abdominal/back pain with weight loss or greasy stools.
  • Get urgent medical care if you have severe abdominal pain, trouble keeping food or fluids down, or symptoms of a blood clot (sudden swelling and pain in a leg or arm).

Important note

These symptoms are common and are much more often caused by conditions other than pancreatic cancer, such as gallstones, stomach ulcers, or routine digestive issues. However, because pancreatic cancer can be aggressive, any persistent or worsening combination of the symptoms above should be checked by a healthcare professional promptly.
