The statement that there are 4 symptoms of stomach cancer when eating is not true. Early stage patients may have no obvious symptoms; progressive stage may have indigestion, stomach discomfort and other manifestations. Gastric cancer is a malignant tumor caused by Helicobacter pylori infection, heredity and other factors, and early patients often have no specific clinical manifestations or even no symptoms after the disease. As the disease progresses, dysphagia, stomach discomfort and indigestion may occur during eating. In addition, there may be loss of appetite, black stools, vomiting or vomiting blood, abdominal masses and other clinical manifestations, and even perforation, pylorus and cardia obstruction. Patients should go to the hospital for examination when they have similar manifestations, in order to make a clear diagnosis as early as possible and avoid delaying their condition.
