Abortion Breast Cancer - a myth?
|An article in the Lancet rehashed the
subject of the link between abortion and breast cancer. Dr Beral, the lead
scientist concluded that there was insufficient proof of a link - she based
this conclusion on her metastudy of several available studies. The media
triumphantly picked up the headline, shouting that the abortion breast
cancer link was a "myth".
An article in the November edition of the journal "Ethics and Medicine" points out that Beral's metastudy was flawed and if it had been organized in a better manner, it would have NOT "disproven" the link.
Below is a brief listing of the fatal flaws in Dr Beral's study, flaws which you will never read in the mass media:
1. Beral selected 24 studies (slightly over half) out of 41 possible studies and she excluded 3 of HER OWN studies and included 3 studies which have been proven to be flawed due to poor data collection including the famous Melbye study which listed 60,000 women who had had abortions (and got breast cancer) as NEVER having abortions, because they aborted before the computer records were kept. Were these 60,000 women added to those who had HAD abortions, the Melbye study would have shown a higher percentage of breast cancer among aborted women than some of the other studies.
By being selective with the studies included in her metastudy, Beral can skew the statistics by excluding those studies which would provide "the wrong answer" to her premise. If the reasons for which she eliminated half the studies, were applied to ALL of the studies, those studies she chose to include should have been eliminated also.
2. She chose an invalid control group. She compared aborted women to women who had never been pregnant when it is well known women who have never been pregnant are a high risk group for breast cancer because a woman's body changes dramatically hours after conception. She should have compared women who had carried full term to women who had aborted.
This comparison of women who had never BEEN Pregnant to aborted women showed LESS difference in risk of breast cancer between the two groups because women who have carried FULL TERM have a significantly LOWER risk of breast cancer than women who have never been pregnant. (This risk of breast cancer in women who have never been pregnant has been known for decades because I heard about it when I was a kid). So in other words, she compared a high risk group (women who have never BEEN pregnant) with aborted women to skew the results.
From Dr Lanfranchi's article: (details on why women who have never been pregnant are higher risk for breast cancer as are women who abort or deliver before the 32nd week of pregnancy)
