Noncancerous stomach polyps are retnoved using endoscopy.
If carcinoma is confined to the stomach, surgery is ustally performed to try to cure it. Most ог all of the stomach and nearby lymph nodes are removed. The prognosis is good if the cancer hasn't penetrated the stomach wall too deeply. In the United States, the results of surgery are often poor because most people have extensive cancer by the time a diagnosis is made. In Japan, where cancers are detected earlier by mass screening using endoscopy, the results of surgery are better.
If carcinoma has spread beyond the stomach, the goal of treatment is to ease the symptoms and prolong life. Chemotherapy and radiation therapу may relieve symptoms. Sometimes surgery is used to relieve symptoms. For instance, if the passage of food is obstructed at the far end of the stomach, a bypass operation may relieve the symptonms. A connection is made between the stomach and the small intestine that allows food to pass. This connection relieves the symptoms of obstruction-pain and vomiting-~at least for a while.
The results of chemotherapy and radiation therapy are better for gastric lymphomas than for carcinomas. Longer survival and even cure are possible.
