Dr. Leon Yoder: The diagnosis of stomach cancer is made through endoscopy by an EGD. When we take a look into the stomach, we'll see areas that are inflamed. Sometimes they look like growths. Sometimes they're very flat. But usually, there's an abnormality that's quite obvious to a gastroenterologist. By taking biopsies of these areas that are abnormal looking, you can diagnose a stomach cancer. Not only can you diagnose it, but you'll know the type of stomach cancer that is present. The pathologist will tell us this is a specific type of cancer, and then we know what kind of treatment is going to be the best, whether it's going to be chemotherapy, radiation, whether it's going to be a surgical-type of treatment, or is it going to be ablative-type of treatment.
