The early symptoms of pancreatic cancer are varied and atypical, and many of them are similar to diseases of the upper gastrointestinal tract. It is often treated as a stomach disease in outpatient clinics.” Pancreatic cancer is insidious in its onset, but it is not without its clues. Early symptoms of pancreatic cancer #1: Recent unexplained abdominal pain. Abdominal pain is an early symptom of pancreatic cancer, mostly seen in pancreatic body and tail cancer, located in the upper abdomen, around the umbilicus or right upper abdomen, colic in nature, paroxysmal or persistent, progressively aggravated dull pain, mostly radiating to the lumbar back, aggravated in lying position and at night, and can be relieved when sitting, standing, leaning forward or walking. Early symptoms of pancreatic cancer II: obstructive jaundice Jaundice can be present at a certain stage of the disease process, generally jaundice is more common in pancreatic head cancer and appears earlier. Jaundice is mostly obstructive, progressive and deepening, accompanied by itchy skin, urine color like strong tea, and feces of clay color. Most of them are caused by the compression of the common bile duct by cancer of the head of the pancreas, and a few are caused by the metastasis of cancer of the body and tail of the pancreas to the liver or the lymph nodes of the liver/general bile duct. Early symptoms of pancreatic cancer III: Sudden and significant weight loss About 90% of patients have rapid and significant development of weight loss, which is often accompanied by malignant mass in the advanced stage of pancreatic cancer. The causes of weight loss include consumption of cancer, loss of appetite, anxiety, insomnia, digestive and absorption disorders, etc. Sudden weight loss may be pancreatic cancer. If there is stuffiness in the upper abdomen, or persistent unexplained abdominal pain or even back pain, and there is no problem after taking gastroscopy or liver and biliary ultrasound; especially if there is inexplicable weight loss without deliberate dieting, you should be alert to pancreatic cancer. Early symptoms of pancreatic cancer 4: sudden increase in blood glucose Master Zhang is 56 years old and has always been in good health. 3 months ago, he became thin and weak without any obvious cause and was found to have elevated blood glucose during routine outpatient examination. After further examination, it was found that there was a mass in the body of the pancreas and the clinical diagnosis was pancreatic cancer. Many patients with pancreatic cancer clinically present with varying degrees of unprovoked history of diabetes mellitus. Therefore, hidden pancreatic cancer should be highly suspected and ruled out for those who are over 50 years of age and have no obvious cause of diabetes symptoms. Sudden onset of diabetes without factors that make it develop, such as family history, or obesity, then be on high alert! Early symptoms of pancreatic cancer 5: Indigestion Indigestion is one of the early symptoms of pancreatic cancer. If there is a recent indistinct and unexplained indigestion, but the digestive tract is normal on barium meal examination, then we should highly suspect and rule out hidden pancreatic cancer lesions. Anorexia, indigestion and weight loss are the four early symptoms of pancreatic cancer. About 10% of the early symptoms of pancreatic cancer are anorexia, indigestion and weight loss, and some other experts consider that nacreosis, nausea and vomiting, change of stool habit and wasting are the four early symptoms of pancreatic body tail cancer.
