第1869期:Cancer – not down to chance

It's long been known that giving up cigarettes, reducing alcohol intake and avoiding sunburn can reduce the chances of getting certain types of cancer. But this new study suggests that our lifestyle choices could have an impact on between 70% and 90% of all cancer cases.众所周知，戒烟、减少饮酒和避免晒伤可以降低患某些类型癌症的风险。但这项新研究表明，我们的生活方式选择可能对 70% 至 90% 的癌症病例产生影响。The team at Stony Brook University re-analysed existing cancer data and found that random cell mutation rarely gets to the point of causing cancer without some form of external factor like toxic chemicals or radiation.石溪大学的研究小组重新分析了现有的癌症数据，发现如果没有某种形式的外部因素（如有毒化学物质或辐射），随机细胞突变很少会达到导致癌症的程度。They also found that anyone who moves from a country with a low cancer risk to somewhere with a higher risk becomes more likely to develop cancer themselves. The findings are expected to influence medical advice on avoiding the disease.他们还发现，任何从癌症风险较低的国家搬到癌症风险较高的国家的人，自己患癌症的可能性都更大。预计这些发现将影响避免这种疾病的医疗建议。intake 摄取lifestyle 生活方式mutation 变异，基因突变toxic chemicals 有毒化学物质radiation 放射，辐射
