The most recent estimates of the world-wide incidence of cancer indicate that gastric cancer was in 1990 the second most frequent cancer in the world (after lung cancer), with about 900000 new cases diagnosed every year. Steady declines in the rates have been observed everywhere in the last few decades, but the absolute number of new cases per year is increasing mainly because of ageing of the population. The exact causes of the decline of gastric cancer are not well understood, but must include improvements in diet, food storage (e.g., refrigeration) and, possibly, the decline of Helicobacter pylori infection. Dietary modifications and, possibly, vitamin supplements remain one of the most important tool for the prevention of gastric cancer. Control of H. pylori infection, by means of eradication or immunization, is also likely to offer great potential for the prevention of this important malignancy.
最近对全球癌症发病率的估计表明，胃癌在1990年是世界上第二常见的癌症（仅次于肺癌），每年约有90万新病例被诊断出来。在过去几十年里，各地的发病率都在稳步下降，但每年新增病例的绝对数量仍在增加，这主要是由于人口老龄化。胃癌发病率下降的确切原因尚不完全清楚，但肯定包括饮食改善、食物储存（如冷藏）以及幽门螺杆菌感染率的下降。饮食调整以及可能的维生素补充仍然是预防胃癌最重要的手段之一。通过根除或免疫控制幽门螺杆菌感染，也很可能为预防这种重要的恶性肿瘤提供巨大潜力。
