smoking leaves an archaeological record of the hundreds of DNA mutations it causes,scientists have discovered。科学家研究表明,吸烟者不会引起DNA变异Having Sequenced thousands of tumour genomes,they found a 20-a-day smoker would rack up an average of 150 mutations in event这种变异是永久持续的,即使吸烟者戒烟也是不可逆转的。

researchers say analysing Tumour DNA may help explain the underlying causes of other cancers。研究人员表示,肿瘤DNA分析有助于解释其他癌症的深层原因。Pamela pugh,69,Was Diagnosed with lung cancer in 2013 . she Started Smoking Aged 17 and quit in her Early 50s . 69岁,Pamela Pugh于2013年接受临床治疗,她从17岁开始吸烟。

but she said : even though I gave up many years ago,the effects of smoking caught up with me。但是她说:“虽然几年前戒烟了,但是吸烟者的影响依然存在。””””””Had I Known As A Teenager That Smoking Caused Mutations Which Would Stay With me For Life Then I would never Had Started“小时候告诉吸烟者基因突变会跟随我一辈子,The study,in the journal science,was carried out by an international group,Including The Wellcome trust Sanger inss该研究发表在《科学》期刊上,名为The analysis shows a direct link between The number of cigarettes smoked in a life time and The number of mutations in tumour DNA。
