Very often no symptoms appear until the cancer is in the advanced stage. Some of the common symptoms are:

• Upper abdominal discomfort and pain 

• Persistent indigestion 

• Loss of appetite 

• Blood in faeces or black tarry stools 

• Persistent vomiting and nausea

• Loss of weight 

• Belching, heartburn after meal

• Feeling full easily after eating

These symptoms can also be due to gastric ulcer or gastritis. Consult your doctor if such symptoms persist.
