Abstract
An initial analysis of data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) registries shows that the age-adjusted incidence rate of breast cancer in women in the United States fell sharply (by 6.7%) in 2003, as compared with the rate in 2002. Data from 2004 showed a leveling off relative to the 2003 rate, with little additional decrease. Regression analysis showed that the decrease began in mid-2002 and had begun to level off by mid-2003. A comparison of incidence rates in 2001 with those in 2004 (omitting the years in which the incidence was changing) showed that the decrease in annual age-adjusted incidence was 8.6% (95% confidence interval [CI], 6.8 to 10.4). The decrease was evident only in women who were 50 years of age or older and was more evident in cancers that were estrogen-receptor–positive than in those that were estrogen-receptor–negative. The decrease in breast-cancer incidence seems to be temporally related to the first report of the Women's Health Initiative and the ensuing drop in the use of hormone-replacement therapy among postmenopausal women in the United States. The contributions of other causes to the change in incidence seem less likely to have played a major role but have not been excluded.

来源于国家癌症研究院，流行病学调查结果的最初的分析数据证实，2003年龄差异修正后的美国女性乳癌的发病率同2002年相比陡降6.7个百分点。2004年基本和2003年持平。 Post is deletedxunl9 wrote:
这个里面的那个完全是我自己翻译的，我并不认为我是错的。而且和漂亮瓶的交流中，我们也探讨了这一点，英语翻译中有直译和意译两种方式，我们取其主要内容。英文不是我们的母语，大家只是根据个人的理解，翻译后的东西是大家共同认定的东西就可以的，不知道为什么不能加分！
附 漂亮瓶给我的悄悄话，不知道为什么用悄悄话，对了就对了，错了就错了，不好意思说？
