You should see your GP if you notice a change that isn't normal for you. They will do some tests and may refer you to a specialist if they think your symptoms could be due to stomach cancer.
The type of stomach cancer you have depends on what type of cell it started in. The grade tells you how abnormal the cells look under a microscope. Adenocarcinoma is the most common type of stomach cancer.
The stage of a cancer tells you how big it is and how far it’s spread. It helps your doctor decide which treatment you need.
Your treatment depends on whereabouts your cancer is in the stomach. How big it is, whether it has spread anywhere else in your body and your general health.
Survival depends on many factors including the stage of your stomach cancer when you are diagnosed and how it has responded to treatment. The figures for stomach cancer survival can only be used as a general guide.
