In recent years, the incidence of pancreatic cancer has become more and more common, and pancreatic cancer is very harmful to patients’ health. Therefore, in our daily life, we need to know the early symptoms of pancreatic cancer in advance in order to treat pancreatic cancer timely and effectively. 1.Patients with pancreatic cancer usually have distension or slight pain behind the sternum. This symptom does not occur continuously, but is intermittent or aggravated after exertion and when eating fast. This is because the esophagus itself is peristaltic at any time, and the symptom will appear only when it peristalsis to the lesion site. 2.Patient’s foreign body sensation when swallowing food. During swallowing, food (especially dry and hard food) passing through the lesion area (the lesion is very small) may produce a foreign body sensation, and often fixed in one part, some patients describe the sensation like having never finished swallowing something. Because the symptoms are mild and occur intermittently, it is easy for patients to neglect. 3, swallowing stagnation or frustration, that is, the patient swallowing food seems to have a momentary stagnation in a certain part of the frustration of the feeling, this situation is not persistent, only in the development of the lesion is gradually obvious. 4, chest swelling or tightness, and often accompanied by dryness of the throat. Patients complain that there is always a stuffy phenomenon in the front part of the chest, which seems to be blocked by an object and makes the chest feel tight, which is especially obvious when swallowing food, but it does not affect normal life and work. 5. Fullness and light pain in the fossa, subxiphoid region or upper abdomen, which is more obvious when eating dry food, but it does not occur every time and is intermittent. This is often an early symptom of cardia cancer. The above early symptoms usually last for more than 3 months, and when they occur frequently, persistently and worsen, they are no longer in the early stage.
