A Mediterranean diet lowers the risk of stomach cancer, as does the stopping of smoking. There is tentative evidence that treating "H. pylori" decreases the future risk. If stomach cancer is treated early, it can be cured. Treatments may include some combination of surgery, chemotherapy, radiation therapy and targeted therapy. If treated late, palliative care may be advised. Some types of lymphoma can be cured by eliminating "H. pylori". Outcomes are often poor, with a less than 10% five-year survival rate in the Western world for advanced cases. This is largely because most people with the condition present with advanced disease. In the United States, five-year survival is 31.5%, while in South Korea it is over 65% and Japan over 70%, partly due to screening efforts.
