  现代生活中,青年人患胃癌常被误诊为胃炎、胃溃疡等疾病,以致确诊时,疾病已向一个或多个邻近脏器转移,失去早期诊断及根治的机会。年轻人得了胃癌,胃酸分泌可以正常,胃蠕动功能受影响不大,消化道症状出现较晚,因而导致误诊、漏诊。

  

  有肿瘤学专家指出,年轻人胃癌增多与以下不良的生活方式密切相关。

  饮食不当 相当一部分年轻人有不良的饮食习惯,如嗜食咸鱼、咸肉等腌制食品,喜好熏烤食物。这些食物中含硝酸盐较多,在胃内可转化为亚硝胺类化合物,此类化合物是诱发胃癌的“元凶”。再者,熏烤食物还含有致癌物质苯并芘。有的年轻人吃饭狼吞虎咽或食之过饱,经常加重胃肠负担。还有的年轻人对新鲜蔬菜不感兴趣,而新鲜蔬菜中含有的维生素能阻断亚硝胺在体内的形成。很多年轻人饥一顿,饱一顿,经常不吃早餐,有时又暴饮暴食,加之生活无规律,亦是胃癌发病的诱因。

  常吃夜宵有研究发现,常吃夜宵易引发胃癌。首先,胃黏膜上皮细胞的寿命很短,四五天就要更新一次。这种再生修复一般是在夜间胃肠道休息时进行的。如果经常在夜间进餐,胃肠道得不到必要的休息,其黏膜的修复也就不可能顺利地进行。其次,夜间睡眠时,吃的夜宵长时间停滞在胃中,可促进胃液的大量分泌,对胃黏膜造成刺激,久而久之,易导致胃黏膜糜烂、溃疡,抵抗力减弱。如果食物中含有致癌物质,例如常吃一些油炸、烧烤、煎制、腊制食品,食品长时间滞留在胃中,更易对胃黏膜造成不良影响,进而导致胃癌。

  长期吸烟饮酒

  吸烟人群患呼吸系统疾病的概率会大大增加,患胃癌的风险也会增加。烟草及烟草烟雾中含有多种致癌物质和促癌物质,如苯并芘、二甲基亚硝胺、酚类化合物、放射性元素等。烟草烟雾中的自由基成分还会破坏遗传基因,损伤细胞膜和降低人体免疫力,促使组织癌变。尤其是在吃饭时吸烟,会使烟草中的有害物质随食物吞下,与胃黏膜接触,长期如此容易导致胃癌的发生。如果在吸烟的同时饮酒,危害则更大。因为烈酒会损伤黏膜组织,从而加大胃黏膜对烟雾中致癌物质的吸收。

  另外,竞争日益激烈的现代社会使年轻人心理压力增加,精神上处于持续应激状态,亦会反馈性地诱发胃部疾病甚至胃癌。
