必克英語：癌癥真的是因為運氣不好所致？很多患者都很容易將這歸結(jié)為運氣之過，但這真的就是運氣不好嗎？其實，癌癥并不取決于運氣而是生活方式絕大多數(shù)的癌癥是由環(huán)境因素造成的，而主要原因并不是因運氣不佳。以下是 Richard Lister 的報道。

　　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。

　　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。

　　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。
