Early symptoms of pancreatic cancer?

Pain is the main symptom of pancreatic cancer, whether located in the head or tail of the pancreas. In addition to the pain in the middle abdomen, left upper abdomen and right upper abdomen, a few cases 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 cancer involves visceral capsule, peritoneum or retroperitoneal tissue, tenderness may occur in the corresponding part.

Jaundice is an important symptom of pancreatic cancer, especially pancreatic head cancer. Jaundice is obstructive, accompanied by dark yellow urine and clay like stool, which is caused by the invasion or compression of the lower end of the common bile duct. Jaundice is progressive, although there may be slight fluctuations, but it can not completely subside. The temporary relief of jaundice is related to the disappearance of inflammation around the ampulla in the early stage. In the late stage, jaundice caused by ampullary tumors is more likely to fluctuate due to the ulceration and decaying of the tumor invading the lower end of the common bile duct. Jaundice only occurs when carcinoma of the body and tail of the pancreas spreads to the head of the pancreas. Some patients with advanced pancreatic cancer have jaundice due to liver metastasis. About 1 / 4 of the patients with refractory skin itching, often progressive.

The most common is loss of appetite, followed by nausea, vomiting, diarrhea or constipation or even black stool, diarrhea is often fat diarrhea. Anorexia is related to the obstruction of the lower end of the common bile duct and pancreatic duct by tumor, and the inability of bile and pancreatic juice to enter the duodenum. Obstructive chronic pancreatitis of the pancreas leads to poor pancreatic exocrine function, which will inevitably affect appetite. A few patients developed obstructive vomiting. About 10% of the patients had severe constipation. Diarrhea due to poor pancreatic exocrine function: fatty diarrhea is a late manifestation, but it is rare. Pancreatic cancer can also occur upper gastrointestinal bleeding, manifested as hematemesis, melena. Splenic vein or portal vein embolism due to tumor invasion, secondary portal hypertension, occasionally esophageal and gastric varices rupture bleeding.
