What are the symptoms of gastric cancer?

The early stage of gastric cancer, including stage 0 and stages A and B of 1, is a period with good prognosis. Most patients still have some abnormal feelings, mainly the reactions of some common digestive tract diseases, especially those similar to general gastritis. For example: 1, the heart cavity is empty and heartbroken. This kind of pain is not serious and can be tolerated. It has nothing to do with eating, and it is easy to show when resting quietly. 2, there is a feeling of fullness in the upper abdomen, this feeling is more obvious when eating, usually a small amount of food is full, patients no longer want to eat, and often accompanied by fever and nausea. Because the location is mostly under or on the right side of xiphoid process, it is sometimes misdiagnosed as gallbladder disease. 3 anorexia, especially anorexia meat, especially fat meat, about 50% of patients have the phenomenon that they used to love fat meat and now they suddenly don't like it. Because of eating less and anorexia, patients can lose weight quickly in a short time. 4. Some patients may also have black stool in the early stage. This is because the lesion destroyed small blood vessels. These mild symptoms are often mistaken for chronic gastritis, which fails to attract the attention of patients and doctors. Therefore, people over the age of 40 who suddenly have the above symptoms should have a gastroscopy in time.

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.
