The most typical feature of esophageal cancer is strong discomfort when eating coarse and hard food, which will be temporarily relieved and disappeared after simple treatment. Most people’s symptom performance is very mild, so early symptoms are not easy to be paid attention to, and many patients are already in the middle and late stages of cancer when diagnosed, so it is important to pay attention to the disease reaction in early stage. Here are 5 major categories of early symptoms of esophageal cancer. Early symptom of esophageal cancer I: Dullness or slight pain behind the sternum. 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 any time, and the symptoms will appear only when the peristaltic movement reaches the lesion. Early symptoms of esophageal cancer II: Foreign body sensation when swallowing food. During the process of 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, some patients describe it as a feeling of never finished swallowing. Because the symptoms are mild and intermittent, it is easy to be neglected by patients. Early symptom of esophageal cancer III: stagnation or stuttering sensation of swallowing, i.e. the patient seems to have the feeling of stagnation and stuttering in a certain area when swallowing food, which is not continuous and only becomes obvious gradually after the development of lesion. Early symptom of esophageal cancer IV: feeling of distension or constriction in the chest, often accompanied by dryness in the throat. Patients complained that there is a kind of stuffy phenomenon in the front of chest, which seems to be blocked by an object and makes the chest feel constricted, especially when swallowing food, but it does not affect normal life and work. Early symptom 5 of esophageal cancer: fullness and light pain in the heart fossa, subxiphoid process or upper abdomen, which 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. Before radiotherapy, patients should firstly do a good job of thinking before radiotherapy, so that they can understand radiotherapy and avoid tension and fear, and secondly improve the general condition, pay attention to nutrition allocation, improve local condition and avoid local infection.
