Most cases of cancer are largely the result of bad luck rather than unhealthy lifestyles, diet or inherited genes, new research suggests. Random mutations that occur in DNA when cells divide are largely 11 for two thirds of adult cancers across a wide range of tissues. The 12 third are linked to environmental factors or defective inherited genes. But the scientists warn that poor lifestyle can add to the "bad luck factor" involved in cancer. The researchers analysed published data on the number of divisions of self-renewing stem cells that occur in an average lifetime in 31 different tissues. These results were 13 with the lifetime incidence of cancer in the same tissues. A strong correlation was seen between a particular tissue’s stem cell division rate and its 14 of developing cancer. The more often cells divide, the more likely it is that letters of their genetic code will become jumbled (混乱的), 15 to an increased cancer risk. Overall, the study found that random mutations due to stem cell division could largely explain around 65% of cancer incidence. Professor Bert Vogelstein, from Johns Hopkins University School of Medicine in the US, said: "All cancers are caused by a 16 of bad luck, the environment and heredity, and we’ve created a model that may help quantify how much of these three factors 17 to cancer development. This study shows that you can add to your risk of getting cancers by smoking or other poor lifestyle factors. However, many forms of cancer are due 18 to the bad luck of acquiring a mutation in a cancer driver gene regardless of lifestyle and heredity factors. The best way to eradicate these cancers will be through early 19 , when they are still 20 by surgery."
