Fogelstein et al. Published an article in the journal Science in January 2015 saying that the difference in cancer risk in human tissues can be explained by errors that occur when stem cells divide, the so-called "bad luck". Cancer gene mutations are the result of "bad luck," and another third is due to genetic and environmental factors. A review article distributed by Science magazine said that the debate on the "bad luck" theory of cancer is expected to continue Some experts believe that this study does not mean to deny the importance of preventing cancer by improving the environment and lifestyle, and the British Cancer Research Association believes that cancer cases can be prevented. What does not match the meaning of this text is:. ['The interpretation of "bad luck" is not a panacea, but also has some scientific reason.', 'Abandoning treatment for cancer patients is a rational act.', 'The academic community about the "bad luck" of cancer has been mixed, and no conclusion has yet been reached.', 'Cancer cases are not all preventable.']
