According to the Daily Mail article "While concluding that breastfeeding offered significant protection from cancer, they also noted that the highest reported risk factor in developing the disease was abortion."
So, I look for the research article and find the abstract -
http://www.ncbi.nlm.nih.gov/pubmed/20338838How strange that the major conclusion is this, "Prolonged breastfeeding significantly reduces the risk of breast cancer and this protective effect was supported by a dose-response relationship. Risk due to passive smoking should be emphasized in anti-smoking programmes."
They mention passive smoking, but where is the mention of abortion being the highest risk factor... you'd think it would be in the abstract, no?
I was already poking around at other studies and found that the Sri Lanka one had only 303 participants, the Iran study (
http://www.ncbi.nlm.nih.gov/pubmed/20364336) had 300 participants, and Chinese study (
http://www.ncbi.nlm.nih.gov/pubmed/20193327) was a case-control study that had 200 pairs one with and one without cancer - these were all done with questionnaires and the Chinese also with genetic testing. All the studies had very small sample sizes and there are lots of confounding variables that are hard to control for with questionnaires! The study from China didn't say that abortion was the highest risk factor. It was looking at estrogen-biosynthesis gene morphisms and concluded "Multivariable unconditional logistic regression showed that after adjusting BMI, intake of estrogen, age of first birth, number of abortion and period of breast feeding, the interaction item of CYP17 (T1931C) and HSD17beta1 (A1954G) was strongly and positively correlated to breast cancer (OR = 2.52, 95%CI = 1.54 to 4.11)." Anyhow, you should definitely check this - scroll down to "Confounding factors"
http://en.wikipedia.org/wiki/Abortion_% ... hypothesis And I just love the quote by Professor Jack Scarisbrick - chairman of Life (a pregnancy counseling charity in the UK) "
We have encountered from the pro-abortion lobby manipulation of the evidence on a truly disgraceful scale. This study is further evidence that has been gathering from all around the world that abortion is a major risk factor for breast cancer."
This is fabulous coming from a representative of Life...
