The reason why pancreatic cancer is painless in the late stage

Malignant tumors are becoming more and more common, and so is pancreatic cancer. Patients with pancreatic cancer should be treated in the early stages. In the later stages, some patients find that the symptoms are not obvious, or even painless. The following will introduce to you how pancreatic cancer can be painless in the later stages. Let's take a look at the following introduction.

The reasons why pancreatic cancer is painless in the later stages are:

Pancreatic cancer can directly infiltrate the wall of the common bile duct, or cause obstructive jaundice due to cancer compression in the early stages; as the tumor develops, the cancer adheres to the stomach, duodenum, large intestine, and inferior vena cava, or infiltrates into internal organs, and then infiltrates the superior mesenteric artery and portal vein, causing portal hypertension and symptoms such as ascites; cancer in the body and tail of the pancreas obviously develops into the retroperitoneum and compresses the splenic artery.

The degree of pain in the late stage of pancreatic cancer is: Pancreatic cancer patients often have symptoms of upper abdominal pain. It can be said that upper abdominal discomfort and dull pain are one of the most common symptoms of patients with advanced pancreatic cancer. The location of the patient's abdominal pain is unclear and the range is wide. The more typical locations are mainly located in the middle and upper abdomen and left hypochondrium, and can radiate to the back, chest, and right scapula. The nature of the abdominal pain is mainly manifested as dull pain, heavy tenderness, gnawing pain, etc., which are mostly persistent and generally worsen after meals.

In the middle and late stages of pancreatic cancer, symptoms are obvious, pain in the left upper abdomen is aggravated, and there is significant weight loss. The patient's oral diet can no longer meet the physical needs, so intravenous nutrition is required to improve the nutritional status of the whole body. Patients who have not lost the opportunity for surgery should try to choose active methods and remove the lesions through surgery. Patients after surgery should determine what kind of diet to use based on the condition of the disease and the condition during the operation.
