Common symptoms of pancreatic cancer?

Yellow abdominal pain is the main symptom of pancreatic cancer, and whether the tumor is located in the head or tail of the pancreas. 60% ～ 80% of the patients presented with epigastric pain, and 85% of the patients with epigastric pain could not be resected or were in advanced stage. Pain generally has nothing to do with diet. At first, most of them are mild and persistent, and the pain gradually aggravates. Due to the different location of cancer and the mechanism of pain, abdominal pain can present various manifestations.

The degree of pain is from satiety to discomfort, dull pain to severe pain. There is radiation pain, pancreatic head cancer to the right, and most of the body and tail cancer to the left. Low back pain is a predictor of later stage and poor prognosis. In patients with pancreatic cancer, the tumor may enlarge the pancreas, compress the pancreatic duct, cause obstruction, expansion, distortion and pressure increase of the pancreatic duct, and cause persistent or intermittent pain in the upper abdomen. Sometimes it is accompanied by pancreatitis, causing visceral neuralgia.

The nerve impulses are transmitted to the left and right sympathetic ganglia t6-t11 via the splanchnic nerve and then uploaded. Therefore, in the early stage of the disease, it is often characterized by a wide range of discomfort, dull pain or dull pain in the middle and upper abdomen, which is not easy to locate, and is often aggravated 1-2 hours after eating, so fear of food can reduce the pain aggravated by eating. The rare cases are paroxysmal severe epigastric pain, and progressive aggravation, even intolerable. This is more common in patients with early pancreatic head cancer accompanied by pancreatic duct obstruction. Drinking or eating greasy food induces increased bile and pancreatic juice excretion, resulting in a sudden rise of pressure in the bile duct and pancreatic duct. In addition to the pain in the middle abdomen, left upper abdomen and right upper abdomen, a few patients complained of left and right lower abdomen, periumbilical or total abdominal pain, and even testicular pain, which was easily confused with other diseases. When the tumor involves visceral capsule, peritoneum or retroperitoneal tissue, tenderness may occur in the corresponding part.
