4月15日至21日是一年一度的全国肿瘤防治宣传周，而此时的杨康，已经是一个肺癌晚期病人了。记者问他，知道有个肿瘤防治宣传周吗？一脸倦容的杨康摇摇头：“不知道。”记者追问，“那你知道自己为什么患肺癌吗？”“我不清楚，也想不通，”杨康激动起来，“我平时身体挺棒的啊，怎么突然就得肺癌了呢？”杨康不知道，但是医生知道。根据医生的介绍，41岁的杨康已经有超过20年的吸烟史。在发现病情之前，他的痰中就时不时的带有血丝了。可悲的是，像生活中的很多人一样，杨康根本没有预防癌症的意识，也从没想到过要去医院检查……《世界癌症报告》显示，目前全世界发病率名列前茅的癌症中，死亡率最高的是肺癌、胃癌和肝癌，其致死人数分别占癌症死亡人数的17.8％、10.4％和8.8％。而在我国，危害最大的四种癌症依次是胃癌、肝癌、肺癌和食管癌，4种恶性肿瘤死亡率合计为69.8/10万，占全部恶性肿瘤死亡率的73.97％。此外，宫颈癌和乳腺癌是发病率高、对妇女危害最大的两种癌症。因此，我们把胃癌、肝癌、肺癌、食管癌、宫颈癌和乳腺癌作为六大最具危害 April 15th to 21st was the annual National Cancer Prevention and Publicity Week.
