Stomach cancer. Gastroscope (endoscope) view of a gastric adenocarcinoma (upper right),a type of stomach cancer. An adenocarcinoma is a cancer which arises from glandular tissue in an organ's epithelium (lining). Stomach cancer causes symp- toms similar to those of indigestion or a peptic (gastric) ulcer,and may develop undiagnosed until it has spread beyond the stomach. In such a case,the prognosis is poor,although radiotherapy and chemotherapy may slow its progress. If it is discovered early,a gastrectomy (removal of the stomach) may effect a cure. Stomach cancer is thought to be linked to diet,with a high intake of salty and smoked foods increasing the risk | |
