Early stage of esophageal cancer has no obvious signs, and some patients may feel discomfort behind the sternum after eating, occasional burning sensation, or even pins and needles pain, accompanied by slow eating and mild choking sensation in the esophagus. The main incidence site of esophageal cancer is in the middle part of esophagus, and people’s bad living habits such as smoking, drinking, consuming pickled or overheated food can all contribute to the occurrence of esophageal cancer, and the degree of choking when patients swallow food is relatively mild, and they may be asymptomatic. In early stage of esophageal cancer, the lesions are often confined to the mucous membrane layer and submucous membrane layer, and are not accompanied by lymph node metastasis. Under gastroscopy, congestion, plaque, erosion, and papillae can be seen in the lesion area of esophagus. Warm reminder, patients with early signs of esophageal cancer must consult doctor in time and have pathological examination to confirm, so as not to miss the time of treatment. In life, patients should pay attention to not eating too hot and too scalded food, eat less pickled food, and quit smoking and drinking.
