With a pancreatic problem, cancer or pancreatitis, how long after eating would you feel pain?

Not a reliable sign: Pain after eating is not a reliable sign for pancreatic cancer. Acute pancreatitis causes continuous pain and chronic pancreatitis may or may not have pain.

Variable: There is a wide range in terms of the onset of pain after eating in patients with pancreatic cancer or pancreatitis. This alone is not an accurate way to diagnose either problem. Generally pain that occurs minutes after eating is more related to the stomach, and not the pancreas but there are many exceptions to this generalization. Talk to your doctor and make sure you have a thorough exam.
