Signs and Symptoms
Early pancreatic cancer often does not cause symptoms, and the later symptoms are usually nonspecific and varied. Therefore, pancreatic cancer is often not diagnosed until it is advanced. Common symptoms include:
- Pain in the upper abdomen that typically radiates to the back (seen in carcinoma of the body or tail of the pancreas)
- Heartburn - acid stomach
- Poor appetite or nausea and vomiting
- Diarrhea, loose stools.
- Significant weight loss (cachexia)
- Painless jaundice (yellow tint to whites of eyes (sclera) or yellowish skin, possibly in combination with darkened urine) when a cancer of the head of the pancreas (75% of cases) obstructs the common bile duct as it runs through the pancreas. This may also cause pale-colored stool and steatorrhea. The jaundice may be associated with itching as the salt from excess bile can cause skin irritation.
- Trousseau sign, in which blood clots form spontaneously in the portal blood vessels, the deep veins of the extremities, or the superficial veins anywhere on the body, may be associated with pancreatic cancer.
- Pulmonary embolisms due to pancreatic cancers producing blood clotting chemicals.
- Diabetes mellitus, or elevated blood sugar levels. Many patients with pancreatic cancer develop diabetes months to even years before they are diagnosed with pancreatic cancer, suggesting new onset diabetes in an elderly individual may be an early warning sign of pancreatic cancer.
- Clinical depression has been reported in association with pancreatic cancer, sometimes presenting before the cancer is diagnosed. However, the mechanism for this association is not known.
- Symptoms of pancreatic cancer metastasis. Typically, pancreatic cancer first metastasizes to regional lymph nodes, and later to the liver or to the peritoneal cavity and, rarely, to the lungs; it rarely metastasizes to bone or brain.

Famous quotes containing the words signs and, signs and/or symptoms:
“But I will harden Pharaoh’s heart, and I will multiply my signs and wonders in the land of Egypt.”
—Bible: Hebrew, Exodus 7:3.
“Chaucer sawed life in half and out tumbled hundreds of unpremeditated lives, because he didn’t have the cast-iron grid of a priori coherence that makes reading Goethe, Shakespeare, or Dante an exercise in searching for signs of life among the conventions, compulsions, self-justifications, proofs, wise saws, simple but powerful messages, and poetry.”
—Marvin Mudrick (1921–1986)
“The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the “easy life of the gods” would be a lifeless life.”
—Hannah Arendt (1906–1975)
