Symptoms of pancreatic tumor include lumbar discomfort, occult pain in the left upper abdomen, loss of appetite and jaundice. Pancreatic tumor in the early stage is very insidious and the clinical manifestation is not obvious, and usually when the obvious symptoms appear, it has already reached the advanced stage and the prognosis is poor. Pancreas is a retroperitoneal organ, when pancreatic lesion occurs, it will lead to low back pain, epigastric distension and pain, and the pain is mostly hidden. At the same time, the digestive function of the pancreas will be affected by abdominal distension, dyspepsia and other manifestations. When pancreatic tumor infiltration and metastasis occurs, infiltration to the common bile duct will cause compression symptoms, jaundice and so on. If the above symptoms occur, it is necessary to consult a doctor in time, complete the relevant examination, make a clear diagnosis, early detection and early treatment.
