But that is only half the fight  医疗保健  围攻癌症  科学将打赢抗击癌症的技术战。但那只是战场的一半  THE numbers are stark. Cancer claimed the lives of 8.8m people in 2015; only heart disease caused more deaths. Around 40% of Americans will be told they have cancer during their lifetimes. It is now a bigger killer of Africans than malaria. But the statistics do not begin to capture the fear inspired by cancer’s silent and implacable cellular mutiny. Only Alzheimer’s exerts a similar grip on the imagination.数字是惨烈的。2015年癌症夺走了880万人的生命，只有因心脏病死亡的人数比这更高。约40%的美国人一生中会被告知罹患癌症。对于非洲人来说，如今癌症比疟疾的杀伤力更大。但是统计数据远远不能体现癌症带来的恐惧——细胞变异悄无声息地发生着，却绝不留情。只有阿尔茨海默症能如此抓住人的想像力。  Confronted with this sort of enemy, people understandably focus on the potential for scientific breakthroughs that will deliver a cure. Their hope is not misplaced. Cancer has become more and more survivable over recent decades owing to a host of advances, from genetic sequencing to targeted therapies. The five-year survival rate for leukemia in America has almost doubled, from 34% in the mid-1970s to 63% in 2006-12. America is home to about 15.5m cancer survivors, a number that will grow to 20m in the next ten years. Developing countries have made big gains, too: in parts of Central and South America, survival rates for prostate and breast cancer have jumped by as much as a fifth in only a decade.面对这样的敌人，可以理解人们为何如此关注科学取得突破、发现抗癌良方的可能性。他们的希望并没落空。从基因测序到靶向治疗，由于这些手段取得的进展，近几十年来癌症患者的存活率越来越高。在美国，白血病的五年存活率从上世纪70年代中期的34%提高到2006年至2012年间的63%，几乎翻了一番。美国有大约1550万癌症幸存者，今后十年这个数字将增至2000万。发展中国家也取得了相当大的进步：在中南美洲部分地区，短短十年内，前列腺癌和乳腺癌的存活率上升了五分之一。  From a purely technical perspective, it is reasonable to expect that science will one day turn most cancers into either chronic diseases or curable ones. But cancer is not fought only in the
