大量的研究已经证实,吸烟及大气污染等与肺癌的发生关系密切。但同时,未暴露在这些环境危险因素的个体也会罹患肺癌,说明肺癌的发生除了上述环境危险因素参与外,遗传因素可能也在其发生中有相当重要的作用[1]。流行病学研究表明,肺癌患者的亲属和后代的发病率明显高于普通人群,
A large number of studies have confirmed that smoking and air pollution are closely related to the occurrence of lung cancer. However, at the same time, individuals who have not been exposed to these environmental risk factors may also develop lung cancer, indicating that in addition to the above environmental risk factors, the occurrence of lung cancer may play a significant role [1]. Epidemiological studies have shown that the incidence of lung cancer patients relatives and offspring was significantly higher than the general population,
