Studies have suggested : It is not smoker's lung cancer that smoker's lung cancer is different from

Studies have suggested : It is not smoker's lung cancer that smoker's lung cancer is different from
Canadian researchers say on the 9th, lung cancer which the smoker suffered from and it is not that lung cancer which the smoker suffers from have different gene mutation, it seems not to be the same kind of cancer.
Researchers point out, this discovery has important meaning, because this means that should carry on corresponding research, treat and diagnose to different genetic mutations of different lung cancer, but not adopt the same set of method to all patients.
According to>The report, the researchers of the centre of cancer in British Columbia utilize genetic analytical technique, having compared two groups of lung cancer patient's organization sample, one group is 30 patients who has never smoked, another group is 53 Patient whose name smoked at that time or once smoked.
Analyze and discover, the quantity of DNA sudden change never in smoker's lung tumour is a smoker or once nearly two times of the smoker's, two kinds of patients' lung cancer may have different molecular mechanisms. Have submitted the relevant report at a meeting of research association of cancer of U.S.A. which researchers held in Philadelphia of U.S.A. on the 8th.
Researchers say, carcinogen in the cigarette initiates gene mutation, lead to the fact the cancer cell grows, and new research reveals, it is not that the possibility that a smoker suffers from lung cancer is other carcinogen to cause, do not come from the cigarette.
Because people often thought never the smoker would catch lung cancer, so the person who didn't get lung cancer smoking has usually already arrived in the later period when can't cure when being been made a definite diagnosis of, how to find it is not that a smoker's lung cancer is an important subject in early days.
It is reported, Canada is launching how to carry on the research that lung cancer is being diagnosed in early days effectively. In the past 30 years, Canada adopted the current office procedure, only made the mortality of lung cancer drop by 3%. Researchers hope to find a set of effective lung cancer and sift and check the method, can let the mortality of lung cancer be dropped by 20%. (Reporter Ma Dan )
