Early symptoms of esophageal cancer? In order to reduce the incidence of esophageal cancer, we should master the early symptoms about esophageal cancer and take precautionary measures to control esophageal cancer in effective time. Early symptom of esophageal cancer I: distension 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 area, 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. patients seem 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. How to prevent esophageal cancer? 1.Change bad eating habits, do not eat moldy food, eat less or no sauerkraut. 2.Improve water quality and reduce nitrite content in drinking water. 3.Promote trace element fertilizer and correct the condition of soil lacking molybdenum and other trace elements. 4.Apply Chinese and Western medicines and vitamin B2 to treat esophageal epithelial hyperplasia to block the cancer process. Actively treat esophagitis, esophageal leukoplakia, cardia laxa, esophageal diverticulum and other diseases related to the occurrence of esophageal cancer. 5.Surveillance of susceptible people, popularization of cancer prevention knowledge and raising awareness of cancer prevention.
