    忌食辛辣、煙熏、鹽腌、霉變、腐爛食品：辛辣食物刺激胃粘膜，久而久之損傷胃粘膜；熏制食物產生致癌物可誘發和加重病情；腌制食物中含有硝酸鹽，和食物中的亞硝酸鹽結合后可以形成很強的致癌物質? ?亞硝胺；霉變食物中含有很強的致癌物質黃麴黴素；腐爛的物質可以產生惡臭的致癌物質乙醛。
  2. Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts. among the adducts, o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties, which can eventually lead to chromosomal aberrations, point mutations, and cell death. this lesion also appears to be involved in tumor initiation, particularly in gastric carcinogenesis

    單功能烷化劑n -甲基- n -硝基- n -亞硝基胍（ mnng ）是一種在環境中廣泛存在的化學誘變劑和致癌劑，它能和dna及蛋白質等生物大分子形成加合物（ adduct ） ，其引起的與突變有關的主要dna損傷類型是o ~ 6 -甲基鳥嘌呤，這種損傷與腫瘤尤其是胃癌的發生密切相關。
  3. In our laboratory, a unique mutation detection system using a shuttle vector plasmid has been established to demonstrate that a low concentration of mnng ( 0. 2 m ) can induce nontargeted mutation in mammalian cells : the mammalian cells were exposed to 0. 2m mnng for 2. 5h, then a shuttle plasmid pz189 carrying supf trna gene was transfected into cells after 24h culture. we found a 5 - fold higher mutation frequency of the plasmid replicated in pretreated cells than the spontaneous mutation frequency of the plasmid replicated in control cells. this kind of mutation did not occur immediately after mnng exposure

    我們實驗室曾用一特殊的突變檢測系統，直接證明dna損傷劑可在哺乳動物細胞誘發非定標性突變：首先用低濃度（ 0 . 2 m ）的短壽烷化劑mnng （半壽期為1 . 1hr ）處理細胞2 . 5h后，繼續培養24h ，將重組有用作突變檢測的靶基因supftrna基因的穿梭質粒pz189轉入細胞復制，發現在未受致癌物直接攻擊的穿梭質粒中有較自發突變率高5倍以上的靶基因突變。
  4. Nitrates can turn into nitrosamines - cancer causing compounds

    硝酸鹽類物質能夠轉變為亞硝胺- - -一種致癌化合物。
  5. The us national cancer institute says on its website that the main chemical in stevioside can be converted in a laboratory into a substance that alters genes. further study is needed to determine whether the sweetener can cause cancer, it says

    美國全國癌癥研究會在其網站上指出，甜葉菊甙的主要化學成分在實驗室可以被轉化為能改變基因的物質，而要確定這種甜味劑能否導致癌癥還需進一步研究。

    現認為，不良性格致癌通過三條途徑：一是促進癌細胞生長；二是損傷機體的免疫力；三是改變機體微體酶系的活性，影響其他化學致癌物質的轉變。
