美患肺癌烟客肿瘤中发现5万个基因变异
  (芝加哥路透电)美国科研人员在一名抽烟抽了15年、平均每天抽25根香烟的肺癌患者肿瘤中,赫然发现高达5万个基因变异,数量之多令医生大吃一惊。
  类似研究调查似乎说明,每一根烟都会引发基因突变。以接受调查的该名51岁病患的情况为例,他每抽三根烟就换来一个基因变异。
  参与这项研究的Genentech研究员张泽民(译音)说:“5万个基因是非常庞大的数量,过去从未有研究发现如此多的基因突变。”他表示,这可能与病患的烟龄有关。
  如此惊人的研究结果令科研人员难以置信,他们甚至还不但反复进行检查,并查看病患肿瘤是否有不寻常之处,最后才确认采样无误。

感想:我认为那个人根本就不应该抽烟,因为抽烟会对我们的身体造成很大的伤害。
