Since pancreatic cancer starts insidiously and there are no special symptoms in the early stage, it is difficult to clearly classify the ten early symptoms of pancreatic cancer as stated by patients. The occurrence of pancreatic cancer generally originates from pancreatic ductal epithelium and alveolar cells, due to the difficulty of early diagnosis and the richness of pancreatic blood vessels and lymphatic vessels, it is easy to have early metastasis, therefore, the survival time of patients with pancreatic cancer in the progressive stage is relatively short and it is one of the malignant tumors with the worst prognosis. 1. abdominal pain: abdominal pain often appears as the first symptom, which is persistent and progressively aggravated in the middle The pain in the upper abdomen or lower back is more severe at night. The pain can be relieved to a certain extent when the patient performs spinal extension movements such as supine and lazy back, and spinal bending movements such as prone, squatting and bending. 2. 3. Indigestion: Since pancreatic cancer may block the lower end of the common bile duct and pancreatic ducts, bile and pancreatic juice cannot enter the duodenum normally, so that most patients have symptoms such as lack of appetite, indigestion and foul-smelling stools; 4. The patient’s negative emotions such as anxiety and depression can lead to loss of appetite, which eventually leads to wasting; 5. Patients with pancreatic cancer may have serious psychological burden due to pain, long-term treatment and poor prognosis, which may cause tension, anxiety, fear and depression; 6. If the patient has diabetes, the high blood sugar environment in the body is more harmful to the pancreatic cells and may aggravate the condition of pancreatic cancer; 7. The thrombophlebitis is mainly manifested as red lines along the veins with redness, swelling and pain, and the swollen and congested veins can be palpated. Early diagnosis of pancreatic cancer is difficult. When patients come to the clinic with symptoms such as significant wasting, epigastric pain, jaundice, epigastric mass, etc., imaging examinations such as CT, abdominal ultrasound, ultrasound endoscopy, selective arteriography, etc., if there are signs of pancreatic cancer, although the onset of pancreatic cancer can be clearly identified, most of them suggest advanced stage, and the time for surgery is easily lost. Therefore, it is recommended that patients with a family history of pancreatic cancer, a history of heavy smoking, chronic pancreatitis, etc., which have a higher risk of inducing pancreatic cancer, should have regular annual medical checkups to prevent the disease from occurring.
