Those are the ones I *know* were factored in as demographic factors.
If those are the *only* ones that were used to determine that the Marin
County breast cancer rate is actually really in line with the rest of
the US, environmental factors have *nothing* to do with the *difference*
in breast cancer rates there.
I think that Dr. Dean Edell touched on this sometime last week in his
radio show, and there might be something at www.healthcentral.com about
it. I've gotta finish fixing breakfast for my in-laws, but I may look
it up later.
