- 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
- have a brother, sister or parent who had stomach cancer
Many stomach cancers are also linked to lifestyle.
You cannot always prevent stomach cancer. But making healthy changes can lower your chances of getting it.
