我国癌症发病率逐年上升,每年新发癌症患者180万,每年死于癌症的人数超过1 40万。卫生部统计,2000年我国城市中癌症死亡人数已经超过心脑血管病占据首位,在农村中占第2位。而且专家预测,由于我国目前环境污染、吸烟问题以及不良饮食习惯等问题仍然严重,在2025年前癌症发病率不大可能下降,因此癌症已成为一种我们每个人必须面对的多发 The incidence of cancer in our country has been increasing year by year. There are 1.8 million new cancer patients each year, and more than 1.4 million people die of cancer each year. According to the statistics of the Ministry of Health, in 2000, the number of cancer deaths in urban areas in China exceeded the number of cardiovascular and cerebrovascular diseases and ranked second in rural areas.
