For the early symptoms of esophageal cancer, if people have certain understanding, they can have timely treatment, so what are the symptoms that need early attention? During the process of swallowing food (especially dry and hard food) passing through the lesion area (the lesion is very small) may produce a foreign body sensation, and it is often fixed in one part, and some patients describe it as a feeling that they can never finish swallowing. Because the symptoms are mild and intermittent, it is easy to be neglected by patients. 2.Posterior sternal distension or mild pain. This symptom does not occur continuously, but intermittently or worsens after exertion and when eating quickly. This is because the esophagus itself is peristaltic at all times, and the symptoms only appear when the peristaltic movement reaches the site of the lesion. 3. A sense of stagnation or stuttering may occur during swallowing. This is because the patient seems to have the feeling of stagnation and stuttering at a certain place when swallowing food, which is not continuous and only becomes obvious after the lesion develops. 4.Fullness and light pain in the heart fossa, subxiphoid or epigastric region. It is more obvious when eating dry food, but it does not occur every time but intermittently. 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. 5.In addition, patients with esophageal cancer will have chest tightness and often dryness in the throat during the disease. The patient complains that there is a kind of stuffiness in the front of the chest, which seems to be blocked by an object and makes the chest feel tight, especially when swallowing food, but it does not affect normal life and work.
