1. Body weight loss
        Pancreatic cancer is different from other cancers. Patients with other cancers will lose weight only after they develop in the middle and late stages. In the early stages of pancreatic cancer, symptoms of rapid body weight loss will appear.
        When tumors in the pancreas grow, they consume a large amount of protein, lipids and other components in the human body. These components are important tissues that make up human muscles. Once consumed in large amounts, the patient's body will lose weight quickly.

2. Abdominal pain
        In the early stages of pancreatic cancer, patients will experience repeated abdominal pain. After a tumor grows in the pancreas, the tumor easily grows in the direction of the posterior peritoneum. The posterior peritoneum has very rich sympathetic and parasympathetic nerve tissues, which will be strongly stimulated by the tumor, resulting in very obvious abdominal pain.
        In the early stage of the onset, the patient's upper abdomen will have intermittent dull pain and swelling pain. However, this kind of intermittent dull pain will not last long, and patients will have symptoms of progressively worsening abdominal pain. The painful part is located in the upper middle abdomen. Whether the patient is in the day or at night, the patient will have persistent abdominal pain.
        In severe cases, the patient can only adopt a series of postures such as bending the waist, curling up, lying on the side, etc., to achieve a slight relief of pain. If it progresses to the middle and late stages, the patient will experience severe abdominal pain and low back pain.

3. digestive tract symptoms
        Most patients with pancreatic cancer will have a series of gastrointestinal symptoms at the beginning of the onset. These symptoms are similar to those with some gastritis, or gastric diseases such as gastric ulcers, so they are easy to be ignored by patients.
        The digestive system is severely affected by the growth of tumors in the pancreas. As a result, the patient will experience a series of abdominal distension, loss of appetite, and frequent nausea or vomiting.

4. jaundice symptoms
        Jaundice is a more obvious symptom after suffering from pancreatic cancer, especially pancreatic tumors located in the head of the pancreas. Due to compression to the common bile duct, bile cannot be excreted normally. The bile will flow back into the blood, causing the patient to show symptoms of jaundice. The patient’s skin will have progressively worsening yellow stains. In addition, the whites of the eyes and urine will turn yellow and dark.
        All in all, when suffering from pancreatic cancer, most patients will have the above 4 more obvious manifestations.
        In addition, about 50% of patients will show symptoms related to diabetes, such as polydipsia, polyuria, polyphagia, weight loss, and increased blood sugar.
        Once these symptoms appear, you must quickly go to a regular hospital for treatment and treatment, in order to maximize the life of the patient.
