The chance of getting esophageal cancer one year after gastroscopy is uncertain, after all, it is not a short time, it depends on the condition, and the reference value is not too big. If the gastroscopy result is normal one year ago, and there is no family history of cancer and no bad habits, then the possibility of esophageal cancer is relatively small. If there are symptoms related to suspected esophageal cancer such as difficulty in swallowing or painful swallowing, gastroscopy can be done again if necessary, and if necessary, CT of chest or barium meal imaging can be used to further clarify the diagnosis. In other words, if the symptoms are very similar to esophageal cancer, even if you had a gastroscopy 1 year ago, you should review the gastroscopy. It is because some patients with early esophageal cancer have atypical endoscopic presentation, which is relatively flat and the distinction with surrounding normal mucosa is not clear, and some endoscopists may lack experience in identifying early esophageal cancer, resulting in early esophageal cancer being missed a year ago. If there is precancerous lesion of esophageal mucosa when gastroscopy was done a year ago, it is more necessary to set to review. The current gastroscopy technology has been greatly improved, and some gastroscopes can distinguish the diseased mucosal area from the normal mucosa by special photoelectron staining technology, which can better detect early cancerous lesions. Esophageal cancer mainly manifests itself as progressive feeding is the slow passage of absolute food in the esophagus, that is, difficulty in swallowing. If you have the above symptoms, you need to review the gastroscopy in time to clarify the specific situation.
