Gastric cancer is a malignant tumor that occurs in the stomach. Early stage of gastric cancer may have no obvious clinical manifestations, while more common clinical manifestations in the progressive stage include epigastric pain, poor appetite, dyspepsia, nausea and vomiting, emaciation, anemia, weakness, and epigastric mass, etc. Complications or metastasis may occur with corresponding special symptoms.
Most of the early gastric cancers have atypical clinical manifestations or occasional indigestion. The more common manifestations of advanced gastric cancer include epigastric pain, weight loss, palpable mass in the epigastric region with pressure and pain, anorexia, anemia and fatigue.
Complications or metastasis of gastric cancer will often be accompanied by some special manifestations, for example, if gastric cancer has ulcers, bleeding from ulcers will cause vomiting of blood, black stools, and anemia; if pyloric obstruction occurs, there will be nausea and vomiting and vomiting of overnight food; metastasis to the lungs will cause coughing and hemoptysis; and metastasis to the liver will cause liver enlargement, jaundice, and pain in the upper right abdomen, etc. Once similar clinical manifestations as mentioned above occur, it is suspected that gastric cancer may cause pain in upper abdomen.
If you suspect stomach cancer with the above mentioned clinical manifestations, you should go to regular hospitals as soon as possible to complete the relevant examinations to avoid delaying the condition.
