年轻人患胃癌 不良生活、饮食习惯是主因
据统计，目前我国每年新发现胃癌患者约40万，占世界胃癌发病人数的42%。好发年龄为40-60岁，30岁以下的胃癌患者被称为青年人胃癌。据国外文献报道，青年人胃癌占胃癌总数的2.01%，而我国的数据却高达7.6%，青年人胃癌患者呈逐年上升趋势。年轻人不良生活、饮食习惯是患病主因
为什么青年人胃癌会不断增多呢？专家解释道，这多与年轻人不良的生活习惯有密切关系，过量吸烟、饮酒和饮食不当都已成为青年人易患胃癌的重要原因。
目前，许多青年人有嗜烟、酗酒的习惯，但他们往往会忽略过量吸烟是青年人易患胃癌的重要原因之一，烟雾中含有多种有害物质是导致青年人胃癌的主要因素，如3、4-苯并芘、砷、镍、芳香胺等，而经常过量饮酒，致使胃部受到乙醇的恶性刺激，容易引起胃部慢性炎症，进而使胃粘膜发生不典型增生，最终导致胃癌的发生。
