Pancreatic tumor symptoms?

The main symptom of pancreatic cancer is painless and increasing jaundice caused by compression or obstruction of biliary tract. Due to the lack of bile into the intestine, the patient's stool is white clay like. Cancer of body and tail of pancreas usually has no jaundice in clinic, and its incidence is more serious. Ascites often occurs due to invasion of portal vein, compression of splenic vein, splenomegaly, invasion of celiac plexus and deep pain. At the same time can also have weight loss, anemia, vomiting, constipation and other symptoms.

In the early stage, pancreatic cancer can spread directly to adjacent tissues, such as bile duct and duodenum, and then metastasize to pancreatic head and para common bile duct lymph nodes through lymph nodes. But intrahepatic metastasis is the most common, especially in the body and tail cancer. The cancer tissue can also invade the peri celiac plexus lymph nodes, resulting in distant lymphatic or hematogenous metastasis.

Pancreatic cancer can occur in the head, body, tail or the whole pancreas, but the head of the pancreas is the most common, accounting for 60-70%, followed by the body of the pancreas, and the tail is the least common. The gross appearance of the tumor is round or oval. Some of binajie's tumors are distinct and a little diffuse infiltrating in the adjacent pancreatic tissue, which is difficult to distinguish. Under the microscope, there are mainly three types: adenocarcinoma, undifferentiated carcinoma and squamous cell carcinoma.
