英语翻译
Causes of cancer in the world:comparative risk assessment of nine behavioural and environmental risk factors
Summary:
Introduction :With respect to reducing mortality,advances in cancer treatment have not been as effective as those for other chronic diseases; effective screening methods are available for only a few cancers.Primary prevention through lifestyle and environmental interventions remains the main way to reduce the burden of cancers.In this report,we estimate mortality from 12 types of cancer attributable to nine risk factors in seven World Bank regions for 2001.
Methods:We analysed data from the Comparative Risk Assessment project and from new sources to assess exposure to risk factors and relative risk by age,sex,and region.We applied population attributable fractions for individual and multiple risk factors to site-specific cancer mortality from WHO.
Findings:Of the 7 million deaths from cancer worldwide in 2001,an estimated 2•43 million (35%) were attributable to nine potentially modifiable risk factors.Of these,0•76 million deaths were in high-income countries and 1•67 million in low-and-middle-income nations.Among low-and-middle-income regions,Europe and Central Asia had the highest proportion (39%) of deaths from cancer attributable to the risk factors studied.1•6 million of the deaths attributable to these risk factors were in men and 0•83 million in women.Smoking,alcohol use,and low fruit and vegetable intake were the leading risk factors for death from cancer worldwide and in low-and-middle-income countries.In high-income countries,smoking,alcohol use,and overweight and obesity were the most important causes of cancer.Sexual transmission of human papilloma virus is a leading risk factor for cervical cancer in women in low-and-middle-income countries.
Interpretation:Reduction of exposure to key behavioural and environmental risk factors would prevent a substantial proportion of deaths from cancer.
因为以前悬赏过，没有得到回答，被系统白扣分了，所以一般得到满意答案后再提高悬赏的，结果被大家误会了。

我把复制下来了,这样我好翻一点.
Causes of cancer in the world:comparative risk assessment of nine behavioural and environmental risk factors
世界上引发癌症的因素：9中行为和环境风险因素的相对风险评估
Summary:（概括）
Introduction :With respect to reducing mortality,advances in cancer treatment have not been as effective as those for other chronic diseases; effective screening methods are available for only a few cancers.
介绍：在降低死亡率方面,癌症治疗并没有想别的慢性病一样取得有效进步；有效的屏蔽措施仅对一些癌症有用.
Primary prevention through lifestyle and environmental interventions remains the main way to reduce the burden of cancers.In this report,we estimate mortality from 12 types of cancer attributable to nine risk factors in seven World Bank regions for 2001.
通过生活方式和对环境的干涉来进行初步预防仍然是减轻癌症负担的主要方式.在这片报道中,我们选取了2001年时7个世界银行区域,来评估9个风险因素对12种癌症的死亡率.
Methods:We analysed data from the Comparative Risk Assessment project and from new sources to assess exposure to risk factors and relative risk by age,sex,and region.We applied population attributable fractions for individual and multiple risk factors to site-specific cancer mortality from WHO.
方法：我们分析了从比较风险评估项目和新的来源中的到的数据,通过年龄,性别和地区来评价风险因素和相对风险.我们将对个体的人口归因分数（专业术语我不知道怎么翻）和多种风险引子应用到从世界卫生组织得来的特定地点的癌症死亡率.
Findings:Of the 7 million deaths from cancer worldwide in 2001,an estimated 2•43 million (35%) were attributable to nine potentially modifiable risk factors.Of these,0•76 million deaths were in high-income countries and 1•67 million in low-and-middle-income nations.
发现：在2001年世界范围内700万因癌症死亡的人中,大约243万（35%）的是因为9种潜在的可修正的风险因素.其中,76万是在高收入国家,167万是在低中等收入国家.
Among low-and-middle-income regions,Europe and Central Asia had the highest proportion (39%) of deaths from cancer attributable to the risk factors studied.1•6 million of the deaths attributable to these risk factors were in men and 0•83 million in women.
在地中等收入地区,欧洲和中亚的因被研究的风险因素导致的癌症而致死的比例最高（39%）.因这些风险因素致死的人中,有160万男性和83万女性
Smoking,alcohol use,and low fruit and vegetable intake were the leading risk factors for death from cancer worldwide and in low-and-middle-income countries.In high-income countries,smoking,alcohol use,and overweight and obesity were the most important causes of cancer.Sexual transmission of human papilloma virus is a leading risk factor for cervical cancer in women in low-and-middle-income countries.
吸烟,饮酒,低量的水果和蔬菜的摄入是世界范围和低中等收入国家的主要的风险因素.在高收入国家中,抽烟,饮酒和过度肥胖是最主要的引起癌症的因素.通过性传播的人乳头状瘤病毒是引起中低收入国家女性发生宫颈癌的主要因素.
Interpretation:Reduction of exposure to key behavioural and environmental risk factors would prevent a substantial proportion of deaths from cancer.
解析：减少对主要行为和环境风险因素的暴露可以很大比例上防止因癌症的死亡.
