, also called gastric cancer, is much more common in other areas of the world than it is in the United States, particularly Japan. The number of people diagnosed with the disease each year is declining. In 2008, 21,500 new cases of stomach cancer were diagnosed in the United States.
Risk factors for stomach cancer include age, gender, race and diet. Most people who develop stomach cancer are age 72 or older. Men are more likely than women to get stomach cancer, and it is more common in Asians, Pacific Islanders, Hispanics and African Americans than in non-Hispanic white Americans.
Studies suggest that diets high in smoked, salted and pickled foods may increase chances of stomach cancer. The bacteria helicobacter pylori, commonly found in the stomach, can cause infections which may increase risk of stomach cancer.
