ABSTRACT
<p><b>OBJECTIVE</b>To assess the protective effect of drinking green tea on the development of gastric, liver and esophageal cancers.</p><p><b>METHODS</b>A population based study was conducted in Taixing, Jiangsu province, including 206, 204, 218 cases, respectively, and 415 population controls.</p><p><b>RESULTS</b>Green tea decreased the development of gastric cancer risk by 40%. Dose-response relationships were observed between the length of time, concentration and quantity of green tea drinking and its protective effects on gastric cancer. For individuals who drink green tea for more than 250 g per month, the risk of gastric cancer reduced about 60%. Green tea might have protective effect on liver cancer. However, no protective effect of green tea was observed on esophageal cancer.</p><p><b>CONCLUSION</b>Green tea drinking might be a protective factor for gastric cancer. However, the protective effects of green tea on liver and esophageal cancer were not obvious.</p>
