This certainly doesnt surprise me, since the source is Christian. I would think that the American Cancer Society would be a better source for unbiased info regarding this. Wouldnt you?
Here is a link to a page on the American Cancer Society site that clearly explains that there is not any known link to Abortions and Breast Cancer.

My reading and research indicates that the studies which prove no connection between abortion and breast cancer were done on women "shortly" (ie. two years or less) after their abortions. The more time that passes between the abortion and participation in a study of this nature, the more likelihood of the development of breast cancer.
I have long wondered how many women who develop breast cancer in their 30s had abortions in their early-to-mid teens. I believe there is a direct correlation.
