Cancers and other diseases can cause symptoms. These are changes in your body that you notice. Examples of symptoms are having a cough, a pain or a lump.  

Symptoms can be caused by many illnesses, not just cancer, but it is always best to have them checked out by a GP. 

What you need to know

Stomach cancer symptoms

Sometimes when stomach cancer is in its early stages there may not be any noticeable symptoms.

Symptoms can seem minor but they should not be ignored, especially if they have been present for a while. 

Symptoms of stomach cancer can include:

  • unexplained weight loss and reduced appetite
  • indigestion or heartburn
  • trouble swallowing
  • a feeling of fullness
  • discomfort or pain in the middle of the chest
  • a persistent cough
  • nausea and vomiting
  • blood in the vomit
  • continual tiredness or feeling weak
  • black or very dark coloured faeces.
Most symptoms are not caused by cancer, but it is always best to let your doctor know about any symptoms you have. Cancers that are diagnosed early can be easier to treat.

What to do if you have symptoms
