Stomach cancer can be hard to find early. Often there are no symptoms in the early stages and, in many cases, the cancer has spread before it is found. 

Stomach cancer can cause

the following: 

Indigestion or a burning sensation (heartburn).

Discomfort or pain in the abdomen. 

Nausea and vomiting. 

Diarrhoea or constipation. 

Bloating of the stomach after meals. 

Loss of appetite. 

Weakness and fatigue. 

Persistent low grade fever. 

Black tarry stools.
