                Losing even a modest amount of weight could reduce breast cancer risk: study

                研究表明,即使是减一点点体重也能降低患乳腺癌的风险

                Overweight women over the age of 50 could see a reduction in their risk of developing breast cancer if they lost weight, according to a new study.

                一项新的研究表明,50岁以上的超重女性如果减肥,患乳腺癌的风险№会降低。

                The study, published in the Journal of the National Cancer Institute (JNCI) and conducted by researchers from the American Cancer Society, the Harvard T.H. Chan School of Public Health and others, found that overweight women in “middle or later adulthood” who lost weight and kept it off had a reduced breast cancer risk when compared to overweight women whose weight remained the same.

                该研究发表在《美国国家癌症研究所(JNCI)和由美国☆癌症协会的研究人员,哈佛T.H.陈公共卫生学院和其他发现,超重女性“中老年”减肥和保持它降低患乳腺癌的风险相比,超重女性的体重保持不变。

                To get their results, researchers, using the Pooling Project of Prospective Studies of Diet and Cancer (DCPP), analyzed more than 180,000 women 50 years of age or older from 10 different studies. The women’s weight was periodically assessed, at the beginning of the study, again after five years, then about four years after that.

                为了得到结果,研究人员利用饮食与癌症前瞻性研究(DCPP)的汇集项目,从10项不同的研究中分析了超过18万名50岁以上的女性。在研究开始时,这些女性的体重被定期评估,五年后再评估一次,大约四年后再◎评估一次。

                研究表明,即使是减一点点体重也能降低患乳腺癌的风险

                By the end, the researchers determined that women “with sustained weight loss had a lower risk of breast cancer than women whose weight remained stable and the larger the amount of sustained weight loss, the lower was the risk of breast cancer,” said a news release on the findings from the American Cancer Society.

                最后,研究︾人员认为女性“持续减肥比女性乳腺癌的风险较低的体重保持稳定和持续减肥量越大,降低患乳腺癌的风险,”一个新闻发布会上发布了来自美国癌症协会的发现。

                Specifically, the researchers found that women who lost between 4 and 10 pounds had a 13 percent lower risk than women whose weight remained stable. Those who lost between 10 and 20 pounds had a 16 percent lower risk, while women who lost more than 20 pounds had a nearly 30 percent — 26 percent, to be exact — reduced risk of developing the disease.

                具体来说,研究人员发现,体重减轻4到10磅的女性比体重保持稳定的女性患病风险低13%。那些减了10到20磅的女性患病风险降低了16%,而减了20磅以上的女性患△病风险降低了近30%,确切地说是26%。

                What’s more, women who lost 20 or more pounds continued to have a reduced risk even if they gained some of the weight back, according to the study.

                更重要的是,根据这项研究,那些减了20磅或更多的女性即使恢复了一些体重,她们的患病风险也会继续降低。

                “Our results suggest that even a modest amount of sustained weight loss is associated with lower breast cancer risk for women over 50,” said Lauren Teras, Ph.D., lead author of the study, in a statement.

                “我们的研究结果表明,对于50岁◣以上的女性来说,即使是适度的持续减肥也能降低患乳腺癌的风险,”该研究的主要作者劳伦·特拉斯博士在一份声明中说。

                “These findings may be a strong motivator for the two-thirds of American women who are overweight to lose some of that weight. Even if you gain weight after age 50, it is not too late to lower your risk of breast cancer.”

                “这些发现可能会成为三分之二超重的美国女性减肥的强大动力。即使你在50岁以后增重,现在降低患乳Ψ 腺癌的风险还为时不晚。”

                Though the connection between weight and breast cancer risk is complex, being overweight or obese after menopause does increase the risk of breast cancer, according to the health organization.

                尽管体重和乳腺癌风险之间的联系是复杂的,但根据卫生组织的研究,绝经后超重或肥胖确实会增加患乳腺癌的风险。
