The stomach is an organ between the esophagus and the small intestine. It mixes food with stomach acid and helps digest protein. Stomach cancer mostly affects older people - two-thirds of people who have it are over age 65. Your risk of getting it is also higher if you

  • Have had a Helicobacter pylori infection
  • Have had stomach inflammation
  • Are a man
  • Eat lots of salted, smoked, or pickled foods
  • Smoke cigarettes
  • Have a family history of stomach cancer

It is hard to diagnose stomach cancer in its early stages. Indigestion and stomach discomfort can be symptoms of early cancer, but other problems can cause the same symptoms. In advanced cases, there may be blood in your stool, vomiting, unexplained weight loss, jaundice, or trouble swallowing. Doctors diagnose stomach cancer with a physical exam, blood and imaging tests, an endoscopy, and a biopsy.

Because it is often found late, it can be hard to treat stomach cancer. Treatment options include surgery, chemotherapy, radiation or a combination.
