Epidemiology of cancer in China and the current status of prevention and control

癌症是危害中国居民健康的疾病之一。其每年发病数和死亡数分别占全球的23.7%和30%。由于人口老龄化、工业化、城市化进程的加剧,生活方式的改变等原因,中国癌症的发病数和死亡数仍持续增加,癌症负担已不容忽视。癌症的发生发展是遗传和环境相互作用的结果,除年龄因素外,感染、不良生活方式等与癌症的发病密切相关。目前,国内癌症防控形势严峻,面临极大的挑战,如何实施系统的预防措施,有效降低癌症发病率和死亡率是亟待解决的问题。

Cancer is one of the main diseases that greatly endanger human health. The incidence and mortality rates of cancer in China account to 23.7% and 30%, respectively, across the globe. This figure will further rise because of aging, intensification of industrialization and urbanization, lifestyle modifications, etc. Thus, the burden of cancer cannot be ignored. Cancer is caused by hereditary and environmental factors. Besides aging, other factors, such as infections and unhealthy lifestyles are also related to cancer development. Currently, the status of cancer prevention and control is facing a tremendous challenge. There are still some burning issues to be addressed in regards to implementing prophylactic measures systematically to reduce the incidence and mortality rates of cancer effectively.
