You might be more likely to get it if you:

- have a long-term infection with Helicobacter pylori (H. pylori) – read more about the link between H. pylori and stomach cancer on the Cancer Research UK website
- have certain stomach conditions, such as long-term, severe acid reflux, gastritis or a condition called pernicious anaemia, which affects your immune system

Many stomach cancers are also linked to lifestyle.
