From Ed Friedlanders excellent website, pathguy.com:
* Some anti-abortion activists claim that having an abortion will increase the woman's later risk of getting breast cancer. The Bush administration seems to have endorsed this claim (Nat. Med. 10: 759, 2004), but nevertheless it is probably not true. Now is as good a time as any to bring up "statistical relationships" and the problems they cause. For starters, there seems to be a massive reporting bias (i.e., women with breast cancer confess to having had an abortion, healthy women deny it: Am. J. Epidem. 134: 1003, 1991). The Swedes keep records rather than relying on patient reports, and when these were checked the effect disappeared (Br. Med. J. 299: 1430, 1989). A study from New York based only on examination of reports of fetal deaths and breast cancer cases found a positive correlation; but they did not take into account whether and when the women had term pregnancies. See also Int. J. Cancer 48: 816, 1991. JAMA 275: 283, 1996 & 276: 31, 1996 indicated that there's small, if any, increased risk from an elective abortion. NEJM 336: 81, 1997 found no overall risk. Nor did Am. J. Pub. Health 89: 1244, 1999. Neither did Br. J. Cancer 79: 1923, 1999. Neither did Science 299: 1498, 2003. Neither did Lancet 363: 1007, 2004 (I think this one should have closed the book). Neither did the Scotch study (J. Epid. Comm. Health 59: 293, 2005). A slight, probably bogus, protective effect from having had an abortion: Int. J. Cancer 110: 443, 2004 (Boston). No effect in African-Americans: Cancer Caus. Contr. 15: 104, 2004. No effect from either spontaneous or induced abortion: Arch. Int. Med. 167: 814, 2007 (prospective cohort study).
Stop telling lies for Jebus, people - you'll never get into heaven by being so dishonest. It might also be wise to have a look at the readily-available cancer epidemiology stats published by the NIH, BEFORE you go making laughable statements about there having been no young women with breast cancer "from the middle 60's to the late 80's". That's so outrageously ignorant, it nearly made me wet my pants with laughter when I read it.
Then, of course, I realized that you probably sincerely believe it. That's sad. Very, very sad.
