In clinical practice, pancreatic tumors can be divided into two types: benign pancreatic tumors and malignant pancreatic tumors. In the case of benign pancreatic tumors, the symptoms of patients are not very serious. Epigastric distension or hidden pain and epigastric mass are the main clinical manifestations of pancreatic tumor. Next, there are weight loss, jaundice, gastrointestinal bleeding, various gastrointestinal symptoms and liver metastasis. In addition to jaundice, physical examination may reveal epigastric pain. In the advanced stage, a nodular, hard mass may be palpated in the upper abdomen. If jaundice is accompanied by gallbladder enlargement, it is an important basis for pancreatic tumor. Due to bile accumulation, liver enlargement can often be detected. If the cancer compresses the splenic vein or splenic vein thrombosis, splenomegaly can be found. Pancreatic tumor is a disease with high malignancy, but it is really difficult to detect early, and the surgery is very difficult, even after the surgery, the long-term survival effect is worse than the general tumor, so this will cause great harm to the human body. So, what is the danger of pancreatic tumor to the body? Since they are some advanced stage patients, some of them will out pain, and even some of them are so strong that they can’t sleep all night, so it affects people very much. Early stage pancreatic tumor can be asymptomatic because the lesion is small and confined to the pancreas. As the disease progresses, the tumor gradually increases and involves the gallbladder, pancreatic duct and peri-pancreatic tissues, symptoms such as upper abdominal discomfort and hidden pain, jaundice, emaciation, loss of appetite, indigestion and fever can appear. Obstructive jaundice is the most prominent manifestation of pancreatic head cancer, with an incidence of over 90%. Early stage of pancreatic body and tail may not have jaundice. Jaundice is usually persistent and progressively deepening. In case of complete obstruction, the stool may be clay-colored, and the skin may be brown or bronze in color with itching. The treatment for early stage pancreatic tumor is mainly surgery, and if the surgery is completely removed, the patient has the possibility of obtaining long-term survival. So how to prevent pancreatic tumor? A. Keeping eating regularly can make the pancreas work to form a conditioned reflex, which is beneficial to protect the pancreas. This is also one of the common sense of pancreatic tumor prevention.

Third, eating more fresh fruits and fresh vegetables, and paying attention to maintaining the intake of coarse grains such as cereals, beans and sweet potatoes in daily diet is one of the preventive measures for pancreatic tumor. Relevant experiments have shown that the prevention of pancreatic tumors should know which diet structure containing high fiber, fruits and fresh vegetables are less likely to suffer from pancreatic tumors; and the vitamins and trace elements in them can be anti-free radicals and antioxidants, which are conducive to cancer prevention and anti-cancer.
