In addition, cancer of the stomach associated with a number of environmental factors. Dried, smoked and salted food is associated with increased risk, and in Japan and Iceland, where these types of foods are common, the disease is very frequent. Nitrate food (bacteria additive that can be converted into the harmful nitrite) is also associated with a higher risk of stomach cancer.
