A recent metanalysis (pooling the results of different studies on the same research study) of randomized research studies, motly done in Asia, showed a significant reduction of stomach cancer when a bacteria called Helicobacter pylori was eliminated from patients who were originally found to have the bacteria.
The bacteria is found when a tissue sample of the antrum section of the stomach is tested (by looking at the stomach with an endoscope, a long tube with a maginfying lens on the end). It can be treated with different combination of medicines which include certain antibiotics and stomach acid reduction medicines called proton-pump inhibitors.
This finding suggests that the risk of stomach cancer can be reduced by treating the bacteria in patients where stomach cancer is endemic, such as certain Asian countries.
