This article sites later studies that absolutely refute your claims, noting that J Daling noted irregularities in her own study, and citing later, much more relevant studies.

Btw, the Daling study which was so 'irrefutable,' was apparently a study of 1706 people. Hardly a significant sampling. Also, the 50% increase was an increase of from .4 per 1000 to .6 per 1000 women. Try stating your statistics in less inflammatory terms, and they might get taken more seriously.
Compare that study to the first you quoted, with 163 women, against 272 controls.
Then compare all those studies to the study with some 49 thousand women, and then compare that to the Danish study of some 1.5 million women.
Which studies do you think are more likely to be statistically relevant?

Here's what some liberal fringe organizations have to say about abortion and its relation to breast cancer.

"The National Cancer Institute and the American Cancer Society agree that concerns about breast cancer should not influence a women's decision about abortion. "

"According to the New England Journal of Medicine, published in 1997, induced abortions have no overall effect on the risk of breast cancer, based upon a review of the study in Denmark of 1.5 million women."

Now, to show you how an unbiased report should be made:

While looking all this data over, I did find that one source stated that the connection between abortions performed after 18 weeks and increased risk of breast cancer had not been confirmed or dismissed yet, which means that there is still a chance that there may be a connection in that case, but that there is apparently no connection between abortions performed before the first 18 weeks are up and increased risk of breast cancer.

Now I am off to look over the Daling study itself, and maybe the NEJM, if I can locate them online, so I can confirm for myself what they said, rather than rely on the radicals on both sides of the fence for data. I highly recommend you do the same with any new studies you find before spouting more stats at me.
