Getting diagnosed

Your GP will ask you about your symptoms including what they are, when you get them and whether anything you do makes them better or worse.

They will decide about whether to refer you for tests or to a specialist. If you have a cancer you will have more tests to find out how big it is and whether it has spread. This is called staging. 

Seeing your GP

See your GP if you notice a change that isn't normal for you or if you have any of the possible signs and symptoms of cancer.

Referral to a specialist

Your GP should refer you to a specialist if your symptoms could be due to stomach cancer.


There is no national screening programme for stomach cancer in the UK. Read more about this.


You might have a number of tests to help diagnose stomach cancer or to see how the big the cancer is and whether it has spread (the stage).
