Frequent acid reflux in the stomach in the morning is not necessarily gastric cancer, which needs to go to the hospital and be judged by other symptoms, gastroscopy, pathology biopsy and other tests. Chronic gastritis, gastric and duodenal ulcer and other diseases can also cause the symptom of acid reflux in the stomach in the morning, and it is not the only symptom of stomach cancer. There are no obvious symptoms in the early stage of gastric cancer, but in the progressive stage, there will be epigastric pain, weight loss, anorexia, emaciation, etc. In the terminal stage, there will be malignancy and distant metastasis. It is suggested that patients do not need to worry too much and can go to the hospital for gastroscopy, and according to the situation, take tissues for pathological biopsy to help clarify the diagnosis and carry out relevant treatment.
