Acute pancreatitis and pancreatic cancer are two diseases that occur in the same organ, the pancreas. However, acute pancreatitis is entirely an inflammatory change, often caused by gallstones, alcohol consumption, binge eating, and hyperlipidemia, with some cases being idiopathic. Pancreatic cancer, on the other hand, is a tumorous lesion and is a malignant tumor that generally requires surgery. Many pancreatic cancer patients are already in the advanced stages when discovered, making the surgery difficult to perform. The prognosis for patients is also completely different. After the onset of acute pancreatitis and treatment, the pancreas recovers, the inflammation subsides, and it does not affect a person's lifespan. However, if pancreatic cancer is clearly diagnosed, the lifespan oftentimes does not extend beyond a few years.
