People with stomach cancer often have infection with H. Pylori (a bacterium), but not everyone who has this infection in their stomach will develop stomach cancer. Stomach cancer is more common in East Asia than in Western countries.
You may be at risk if you:
- Are older than 50 years
- Consume substantial smoked foods, salted fish and meat, and pickled foods — eating fruits and vegetables high in vitamins A and C lowers the risk of stomach cancer
- Have a family member with stomach cancer
- Have a type of anaemia that means you cannot absorb enough vitamin B12 (pernicious anaemia)
- Have long-term inflammation of the stomach (chronic gastritis)
- Smoke tobacco
