1.Patients with pancreatic cancer usually have posterior sternal distention or mild pain. This symptom does not occur continuously, but intermittently or aggravated after exertion and when eating rapidly. This is because the esophagus itself is peristaltic at any time, and the symptoms will appear only when the peristaltic movement reaches the lesion site.
2. Foreign body sensation when the patient swallows food. During swallowing, food (especially dry and hard food) passing through the lesion area (the lesion is small) may produce a foreign body sensation, and it is often fixed in one part, and some patients describe the feeling of having something that can never be swallowed. It is easy to be neglected by patients because the symptoms are mild and occur intermittently.
3.Sensation of stagnation or stuttering in swallowing, i.e., the patient seems to have a feeling of stagnation and stuttering in a certain area when swallowing food, which is also not continuous and only gradually becomes obvious after the development of the lesion.
4. A feeling of chest distension or constriction, often accompanied by a feeling of dryness in the throat. Patients complain of a kind of stuffy phenomenon in the front of the chest all the time, as if there is an object blockage, so that the chest is a tight feeling, especially obvious when swallowing food, but does not affect normal life and work.
5.Fullness and light pain in the heart fossa, subxiphoid or epigastric region, 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 and persistently and worsen, they are no longer early.
