根据一份新的研究报告表明,美国1990～1996年间的癌症死亡人数稳步地减少,总下降率为4％。此外,每年诊断的新病例数也下降0.9％。肺癌的减少有助于带动癌发生率的总降低,但是亚特兰大市美国癌症学会的PhyllisA Wingo告诫说,由于更多的年轻人正在步入昅烟的行列,所以这种趋势有可能会改变。Wingo及其来自国立癌症研究所(NCI)和疾病控制预防中心的同事一起在《全国癌症学会杂志》上报道了他们的研究结果。
According to a new study, the number of cancer deaths in the United States between 1990 and 1996 steadily declined, with a total decline of 4%. In addition, the number of new cases diagnosed each year also dropped 0.9%. The reduction in lung cancer can help drive the overall reduction in cancer incidence, but PhyllisA Wingo of the American Cancer Society in Atlanta cautions that this trend is likely to change as more young people are embracing smoking. Wingo, along with his colleagues from the National Cancer Institute and the Centers for Disease Control and Prevention, reported their findings in the National Journal of the Cancer Society.
