It would be best for people to learn to recognize the symptoms of pancreatic cancer

Pancreatic cancer is a type of cancer, which is also a disease that endangers people's lives. People hate it very much. So what are the symptoms of pancreatic cancer ? Many people have this question. Let the experts introduce the answer to this question to us. I hope that reading this article will be helpful to you.

The main symptoms of pancreatic cancer include:

1. Yellow abdominal pain Pain is a symptom of pancreatic cancer, and it occurs regardless of whether the tumor is located in the head or tail of the pancreas. 60% to 80% of patients experience upper abdominal pain, and 85% of these patients who experience pain are no longer able to undergo surgery or are already in the advanced stage. The pain is generally unrelated to diet. Most of the time it is mild at first, and it is persistent pain that gradually worsens. Due to the different locations of the tumors and the mechanisms that cause pain, abdominal pain can present in a variety of ways. The degree ranges from fullness and discomfort, dull pain to severe pain and radiating pain. Pancreatic head cancer mostly radiates to the right, while tail cancer mostly radiates to the left. Pain in the lower back indicates a more advanced stage and a poor prognosis. Pancreatic cancer patients may experience persistent or intermittent distension and pain in the upper abdomen due to the enlargement of the pancreas and compression of the pancreatic duct, which may cause obstruction, dilation, twisting, and increased pressure in the pancreatic duct.

Sometimes pancreatitis is also present, causing visceral neuralgia. Nerve impulses are transmitted to the left and right T6-T11 sympathetic ganglia through the visceral nerves and then transmitted upward. Therefore, the early stage of the lesion often presents a wide range of fullness, discomfort, dull pain or dull pain in the upper and middle abdomen, which is difficult to locate and vague in nature. It often worsens 1-2 hours after eating, so people are afraid of eating to reduce the pain aggravated by eating. Less common is paroxysmal severe upper abdominal pain, which progressively worsens and is even unbearable. This is more common in early pancreatic head cancer with pancreaticobiliary duct obstruction. Drinking or eating greasy food induces increased secretion of bile and pancreatic juice, which causes a sudden increase in pressure in the bile duct and pancreatic duct. These are all symptoms of pancreatic cancer.

In addition to pain in the middle abdomen or left upper abdomen or right upper abdomen, a few cases complain of pain in the left or right lower abdomen, around the umbilicus or the whole abdomen, or even testicular pain, which can be easily confused with other diseases. When the tumor involves the visceral capsule, peritoneum or retroperitoneal tissue, there may be tenderness in the corresponding parts, which is also a symptom of pancreatic cancer.

2. Digestive tract symptoms The most common symptom of pancreatic cancer is loss of appetite, followed by nausea and vomiting, diarrhea or constipation and even black stools. Diarrhea is often steatorrhea. Loss of appetite is related to the blockage of the lower end of the common bile duct and the pancreatic duct by tumors, which prevents bile and pancreatic juice from entering the duodenum. Obstructive chronic pancreatitis of the pancreas leads to poor pancreatic exocrine function, which will inevitably affect appetite. A small number of patients experience obstructive vomiting because the tumor invades or compresses the duodenum and stomach. Due to frequent insufficient eating, about 10% of patients have severe constipation. In addition, about 15% of patients have diarrhea due to poor pancreatic exocrine function; steatorrhea is a late manifestation and is a unique symptom of poor pancreatic exocrine function, but it is rare. Pancreatic cancer can also cause upper gastrointestinal bleeding, manifested as vomiting blood, black stools or only positive fecal occult blood test, with an incidence of about 10%. Gastrointestinal bleeding may occur due to invasion and rupture of adjacent hollow organs such as the duodenum or stomach. The ampullary carcinoma itself may cause bleeding more easily due to septic shock. Occasionally, the splenic vein or portal vein may be thrombotic due to tumor invasion, leading to portal hypertension and rupture of esophageal and gastric fundus varicose veins and massive bleeding.

3. Jaundice is a symptom of pancreatic cancer, especially pancreatic cancer. Jaundice is obstructive, accompanied by dark yellow urine and clay-like stools, which is caused by the invasion or compression of the lower end of the common bile duct. Jaundice is progressive, and although there may be slight fluctuations, it is impossible to completely disappear. The temporary relief of jaundice is related to the disappearance of inflammation around the ampulla in the early stage, and the jaundice caused by the ampulla tumor is more likely to fluctuate in the late stage due to the ulceration and sloughing of the tumor invading the lower end of the common bile duct. Jaundice only occurs when pancreatic body and tail cancer affects the pancreatic head. Jaundice in some pancreatic cancer patients in the late stage is caused by liver metastasis. About 1/4 of patients have persistent skin itching, which is often progressive. Although it is currently believed that the occurrence of itching during obstructive jaundice may be related to the accumulation of bile acid in the skin, a small number of patients without jaundice or mild jaundice may also have symptoms of skin itching. Everyone should pay attention to this symptom of pancreatic cancer.
