Appetite is good, but symptoms of stomach discomfort should not be cancer. If it is stomach cancer it will manifest as loss of appetite and even poor appetite, causing abdominal pain, bloating, nausea, vomiting, acid reflux, and may also manifest as dizziness, chest tightness and weakness. Of course, for people with chronic gastric discomfort, it is best to visit a hospital and, if necessary, cooperate with the doctor to perfect an electronic gastroscopy to help understand whether there are organic lesions in the stomach. If necessary, gastric mucosal biopsies can be taken for pathological biopsy to clarify the presence of gastric cancer or benign gastric diseases. Stomach discomfort is mostly caused by indigestion or benign diseases of the stomach, such as chronic gastritis, peptic ulcer, gastroesophageal reflux disease and so on. Patients are advised to cooperate with the specialist and give regular medication treatment if necessary.
