Pancreatic back pain should be checked by a doctor quickly when accompanied by pain in the upper abdomen that increases after a meal, is persistent or is severe, states Mayo Clinic. The pain can mean acute pancreatitis. The back pain can also signal pancreatic cancer, states the American Cancer Society.
People with pancreatic cancer typically experience back pain, according to the American Cancer Society. The pain develops when the cancer infects nerves around the pancreas. Back pain can also occur when the cancer originates in the pancreas tail or body, grows larger and presses on surrounding organs. If pancreatic cancer is causing the back pain, it is likely that the cancer has advanced to other parts of the body.
