Esophagitis usually does not turn into esophageal cancer after one year. There is no inevitable relationship between esophagitis and esophageal cancer. Long-term chronic inflammatory stimulation without timely treatment may evolve into esophageal cancer. Esophageal cancer is a common tumor of digestive tract, mainly related to biological causes, genetic factors, lack of certain trace elements, chemical stimulation, smoking, alcohol, hot food, unclean mouth and other factors. The typical symptom is progressive dysphagia, initially it is difficult to swallow dry food, gradually it is also difficult to swallow liquid diet, and later it cannot even swallow water and saliva. Some cases of reflux esophagitis may develop into esophageal cancer. For patients with suspicious symptoms, all need to do electronic gastroscopy. The cure rate of esophagitis is very high with timely treatment. Do not eat foods containing more nitrosamines, eat more fresh vegetables and fruits, etc. Try not to eat spicy and stimulating or too hot food to reduce the stimulation of the esophagus. In addition to diet, it is also necessary to check and treat early when discomfort occurs. If you have inflammation, make sure to treat it under the guidance of your doctor. Do not think that minor inflammatory discomfort does not need to be treated, and there is a delay in the condition. Long-term persistent inflammation does not exclude the possibility of malignant changes.
