Prevention:

Stomach cancer cannot be prevented in all cases. With most cancers, prevention involves moderating the lifestyle and environmental exposure factors that seem to be associated with specific type of cancer.   In the case of gastric cancer, this may be difficult, since all the causes are not well understood.

 Individuals, especially those in higher risk groups, such as those with a family history of GI cancer, should eat an adequate amount of fruits, vegetables, and whole grains.

In addition, high-fat foods and animal proteins should only be consumed in moderation. Most importantly, individuals should minimize their intake of dried, salty foods. 

Some researchers believe that there are environmental exposures that can predispose an individual to develop some forms of gastric cancer and that genetic factors may play a role in others. More investigation is needed in these areas.

Future research may shed more light on the causes of gastric cancer and possibly lead to more effective preventive measures.
