Stomach cancer

gastrointestinal system cancer that is located in the stomach

Stomach cancer, or gastric cancer, is a kind of cancer from any part of the stomach. Stomach cancer causes about 800,000 deaths worldwide per year.[1] The odds of survival are 5 to 15%.[2] The life span of someone with stomach cancer is five to fifteen years.[2] This is because this type of cancer can spread faster than other cancers.[2]

Most stomach cancer is caused by Helicobacter pylori infection. Diet foods are not proven causes,[2] but some foods, such as smoked foods, salted fish and meat, and pickled vegetables are associated with a higher risk.
