Abortion and Breast Cancer
流產(chǎn)和乳腺癌
When it comes to certain hot topics, claims about what science has or hasn't proven tend to be thrown around more in the service of one position or another than anything else.
當(dāng)談到某些熱點問題時，有關(guān)科學(xué)已證實的或未證實的那些斷言，往往更多的圍繞著它服務(wù)于哪個崗位而進行。
Somebody may tell you that global warming is absolutely real, for example, and then someone else says it absolutely isn't. Often it's hard to know what the real scoop is.
比如，也許有人會告訴你全球變暖是真的在發(fā)生，然后另一些人又會說絕對不可能。通常我們很難弄清楚實情是什么。
Take abortion, for example. Now, we here at Moment of Science aren't taking a position on abortion one way or another. What we can do, though, is set the record straight on a particular notion that has been floating around recently: namely, the idea that having an abortion increases a woman's risk for breast cancer. Is this true?
用“流產(chǎn)”舉個例子吧。現(xiàn)在，我們“科學(xué)一刻”關(guān)于“流產(chǎn)”沒有任何立場。然而，我們能做的就是弄清最近流傳的一觀念的真相，即流產(chǎn)會增加女性患乳腺癌風(fēng)險。真的嗎？
No, it isn't. This is the latest word from the National Cancer Institute in Bethesda, Maryland, where in February of 2003 a meeting of researchers, clinicians, and epidemiologists was convened at the behest of Congress to answer this and other questions.
不，不是真的。這個觀點來自馬里蘭州貝塞斯達國家癌癥研究所。2003年2月，為了解決該疑問，國會召集了研究員，臨床醫(yī)生和流行病學(xué)家在此召開了會議。
Some initial studies had suggested a link, but more comprehensive studies disagreed. Congress wanted to set the record straight. The NCI looked at all the data and announced: no link.
一些最初的研究表明兩者有關(guān)聯(lián)。但是更全面的研究否認了這一觀點。國會想弄清真相。國家癌癥研究所研究了所有數(shù)據(jù)后宣布：沒有聯(lián)系。
However, they also announced, having a baby reduces a woman's risk of breast cancer. Why is that? It isn't yet known, but the data strongly support a link there—young women who have full term pregnancies are at lower risk.
然而，他們也宣稱，生孩子會減少女性患乳腺癌的風(fēng)險。為什么呢？雖然還不是很清楚，但數(shù)據(jù)大力支持這種關(guān)聯(lián)——有足月妊娠的年輕女性換乳腺癌的風(fēng)險較低。
So let's say it again. Having an abortion doesn't increase your cancer risk, but having a baby does decrease it. People on either side of a controversial topic like this probably would like the facts to be a little simpler, but then, mother nature isn't taking sides.
所以讓我們再說一遍吧。流產(chǎn)并不會增加患乳腺癌的風(fēng)險，但生孩子卻會降低風(fēng)險。像這種有爭議的話題，任何一方的人可能都希望事實變得簡單些。但大自然并不偏向某一方。
