Stomach cancer symptoms

Stomach cancer may not cause symptoms in its early stages. This means that it is usually diagnosed when the cancer is more advanced.

Common symptoms are listed below. These symptoms can also occur in many other conditions and do not necessarily mean that you have cancer. Speak with your general practitioner (GP) if you are concerned.


Stomach cancer symptoms

  • unexplained weight loss or loss of appetite
  • difficulty swallowing
  • indigestion – e.g. pain or burning sensation in the abdomen (heartburn), frequent burping, reflux
  • persistent nausea and/or vomiting with no apparent cause
  • a sense of fullness, even after a small meal
  • swelling of the abdomen or feeling bloated
  • unexplained tiredness, which may be due to anaemia
  • vomit containing blood
  • black-coloured or bloody stools
