British scientist passes the gene with the most large-scale heretofore to investigate discovery, mutation of 64 kinds of gene makes specific person suffers from on lung cancer, the influence is slighter nevertheless. The tall danger crowd that this one discovery decides what to person is to contract lung cancer forward strode again one pace. To a few cancer, for instance breast cancer, medical expert had found the gene mutation that increases sicken risk significantly. But before discovering these 64 kinds cause the gene mutation that suffers from lung cancer risk to increase, the scientist never still finds the gene mutation that increases meet with to have lung cancer risk, and lung cancer divests every year all over the world the life of 1.2 million person.

Investigation of this gene team is by the Richard that is located in the cancer research center that British Sa pauses - Haoersidu and colleague finish, they discover mutation of 64 kinds of gene can be slight increase the risk that contracts lung cancer. These gene mutation are called " low outside show a gene such as rate " , because they are only now and then cause tumor grow. This means these to gene mutates and bring about breast cancer to come on the BRCA mutation that odds increases greatly is different. BRCA is choppy can genetic. Acceded the risk that breast cancer contracts in the woman lifetime of BRCA gene mutation is as high as 80% , the risk that contracts ovarian cancer also increases. The basis circulates disease learns statistic, the breast cancer that because BRCA1 and BRCA2 gene mutate,causes in the United States sends ill number to hold sum total 5% to 10% . According to the data of academy of American country cancer, heart department exists inside Jewish body the rate of the gene mutation that causes breast cancer is higher. The heart of 2% fastens the existence inside Jewish body to increase the gene mutation of breast cancer risk, occurence rate is 5 times of all crowd.

But the gene mutation of new discovery is slighter to the influence of lung cancer sicken. Haoersidu says, the risk that contracts lung cancer than if a kind of gene mutates,perhaps can bringing about the person that be not smoking only does not increase 1% . Some people may be successive nevertheless a variety of gene mutate, the influence causing disease that these gene mutate can be accumulated, because this may comparative of degree increase the risk that contracts lung cancer.

To find the gene that cause disease, haoersidu and work in the same placing analysed the haemal sample of patient of 1529 lung cancer and patient of 2707 blame lung cancer. There are 871 people in everybody is a volunteer, it is a white man entirely. Haoersidu emphasizes saying finally, the lung cancer hazard that mutation of these the gene that cause disease cause compares a kind of life style for very slight, the way of life that he says points to smoking namely. He says, "In fact, the most critical factor that causes lung cancer is smoking. The most critical factor that causes lung cancer is smoking..
