Upper abdominal discomfort is the most common initial symptom of gastric cancer, and about 80% patients are similar to dyspepsia. If abdominal pain occurs, it is generally mild and irregular and cannot be relieved after eating. These symptoms are often ignored by patients and easily mistaken for gastritis or ulcer when seeking medical treatment. Therefore, middle-aged patients should be further examined if they have the following conditions, so as to avoid missed diagnosis: ① There was no history of stomach trouble in the past, but recently there was unexplained epigastric discomfort or pain, which was ineffective after treatment; ② There was a history of gastric ulcer in the past, but recently the epigastric pain changed regularly, and the degree became more and more serious. If the symptoms are relieved, but there is an author in the short term, we should also consider the possibility of gastric cancer and do further examination in time.
Nearly 50% patients with gastric cancer have obvious symptoms of loss of appetite or loss of appetite, and some patients restrict their eating because eating too much will cause abdominal distension or abdominal pain. Unexplained anorexia and emaciation are probably the initial symptoms of early gastric cancer and need to be paid attention to.
Patients with early gastric cancer generally have no obvious positive signs. Except the general condition is weak, most patients only have deep tenderness in the upper abdomen.
