Virtually no mainstream scientist believes that the so-called ABC link actually exists — only anti-abortion activists do. Accordingly, Gold’s article noted right off the bat that the American Cancer Society discounts the “alleged link” and that anti-abortionists have pushed for “so-called counseling” laws only after failing in their attempts to have abortion banned. Gold also reported that the National Cancer Institute had convened “more than a hundred of the world’s experts” to assess the ABC theory, which they rejected.

Gold’s piece was hard-hitting but accurate. The scientific consensus is quite firm that abortion does not cause breast cancer. If reporters want to take science and its conclusions seriously, their reporting should reflect this reality — no matter what anti-abortionists say.

But what happened next illustrates one reason journalists have such a hard time calling it like they see it on science issues.
