The different egg double afterbirth female gets the danger of breast cancer really higher?

The reason that, this problem is put forward, obviously is because the newspaperman reported so a cause of news.United Daily News of this year February 3, then have a translation an article from the square piece of the associated press news, quote a the article publish in American February two sunrises publish of the learned essays of the Institute of the National Cancer of the Journal of, put forward different egg twins sister a ratio the people in general more and easily get the standpoint of breast cancer.This sis comes from well-known plum in the United States medical center(Mayo Clinic), the research object is for 29197 stop menstruating behind women, track the schedule as 10 years.(1986-1996)Result detection together egg twins with general the women compare, the risk which gets breast cancer increased, but the different egg double afterbirth get the possibility of breast cancer, is women generally of 1.7700%(95% trust zone 1.16-2.70), but if all of the different egg twins are daughters, the possibility which then gets breast cancer is generally women of 2.1400%.(95% trust zone 1.21-3.79)The author's explanation, attribute to a hypothesis, that is different egg double afterbirth at growth inside the womb, the maternal estrogen density is higher and the female embryo is subjected to this influence and will easily get breast cancer in the future.



If reader my good friends in, by a happy chance pregnant is a different of egg twins, saw this, from necessarily feel nervous but worry for oneself.But, the viewpoint depended on us, everyone really has no necessity because of a news but unnecessary worry.Academic research's need most is an objective attitude, but newspaperman for causing the reader's attention, usually incline to reach the effect of"startling statement creates a sensation" by unilateral report, increment sell of newspaper point.The academic attitude that our aring real should have would not° until also along together take in to consider the thesis of other researches this problem be right.



The Cancer Epidemiology in March, 1999, on the Prevention of the Biomarkers and, a similar research which has Finland announce, the conclusion is the risk that the different egg double afterbirth female gets breast cancer, with general the women compare, there is basically no difference.Before research in the United States speak of, although the research object has 29197, among them twins just 538 people;But the research of Finland be 13176 twins to the kind!American research tracked for 10 years;But research in Finland then tracked for 20 years!(1976-1995)



Each reader, you like to believe which article of conclusion?On the research that the covariance learn, the number is the United States.Generally speaking, research object's number many of, time of research is long, will relatively have a public's trust, so my a trait of believe the parlance of Finn.Be also say, different egg double the afterbirth be female root need not worried oneself be not with generally female easily get breast cancer.



Calculate the American's research result is correct, in fact also no big deal.All of the different egg twins are daughters in their reports, the possibility which then gets breast cancer is generally women of 2.1400%, but everyone not wanted to neglect 95% trust zone is 1.21-3.79, this is to say, the calculation learn by covariance see, this 2.1400% isn't absolute dependable, it of the number have 95% possibilities is fall at 1.21 with 3.79 it.Be also say, all of the different egg twins are daughters and then get the possibility of breast cancer perhaps and only is women generally of 1.2100% just.Besides incidence rate someone of breast cancer grow of difference, the data of the American public hygiene department show, currently eight each American womans, in the middle in the lifetime have 1 will get breast cancer, but past decade come, American female of the incidence rate of breast cancer, already each 110 people of 100,000 people;But basis our country the covariance of the Department of Health , the incidence rate of breast cancer of Taiwanese region female in Year 84 of the Republic of China, the 100,000 people is 24.37 people each time, can not compare with the United States of quarter.Calculate a different egg double afterbirth to get breast cancer of nearly is really an ordinary people of 200%, our country of different egg double afterbirth female, the opportunity to get breast cancer still doesn't arrive generally the American female's half.Therefore although American woman to any the newses of breast cancer all have a plant a soldier all of felling, the our country women really greatly need not immediately dance.



However the words say that come back, along with life style more and more western turn, breast cancer is this problem and also seem to be important more and more in the our country.The time in Year 70 of the Republic of China, the Taiwanese region women die in the number of breast cancer, each don't arrive 4 people in 100,000 female populations.But Year 87 of the Republic of China, the Taiwanese region is each in 100,000 females, unexpectedly have 9.36 people to die in breast cancer and fully increased 200% not only.Opposite but speech, die in the number of cervical cancer, but keep steady in same times, increase.The reason that, the death rate of the cervical cancer gets a control and everyones' know is the achievement that the cervix puts on a slice and put on the slice can screen out a cervical cancer patient of earlier period and make them get the opportunity that can cure.But the screen of our country breast cancer, in this two years just just start.Therefore ignoring is BE not different egg double afterbirth, women's compatriots all should study a routine breast self-examination, and progressively attend the breast cancer screen that the health unit hold to insure an own health
