Clarification On DIM And Its Uses For Breast Cancer
Back to work! I’ve been moving from Colorado to Australia, hence the very quiet period on the website. Just before leaving, I had the opportunity to get some clarification on DIM and its uses for breast cancer from Naturopath Dr Jacob Schor, whose views on various health matters have appeared on this blog previously, most notably in these two articles:
I was quite upset when I wrote that first article, but I am letting it stay on this site in the event that other women are given the same information about DIM – that it acted like Tamoxifen. That does not appear to be the case, but it does have some therapeutic value for breast cancer. Read on.
Once you’ve read the above two articles, and the lengthy article that Dr Schor wrote about estrogen metabolite ratios, you’ll understand better what the issue is with regard to DIM and the old theory of how it supposedly worked.
Basically, natural health care providers have been – for years – recommending the supplement DIM for their patients who have estrogen receptor positive breast cancer but they have been basing their recommendations on a theory that just hasn’t been proven to be true.
Wait! Don’t Throw The DIM Out Yet!
Dr Schor, in a recent email to me, shared with me the following: “That theory is used to justify DIM use but we shouldn’t mix the two up. Just because the theory doesn’t work doesn’t mean that DIM doesn’t work. Because it seemed to lock in to the theory, all benefits were thought to come from its effect on estrogen metabolites. I’m not sure that is so but I am also not sure we should throw DIM in the trash. I think we need to think twice about testing 2 vs 16 metabolite ratios, that we should not think these lab tests are prognostic and we should not be in a rush to move them one way or another.

BreastDefend™ prevents breast-to-lung cancer
BreastDefend™ is a product that is readily available in the USA but I’m not aware of it being available in Australia or the UK yet.
Dr Schor advises us: “So don’t throw out the DIM, throw out the reasons why people thought it was good. It’s not tamoxifen. It’s not an aromatase inhibitor. It’s something else.”
Dr Schor’s qualifications are Naturopathic Doctor, Fellow American Board of Naturopathic Oncology, Associate Editor, The Natural Medicine Journal, Board Member and President, Oncology Association of Naturopathic Physicians (www.OncANP.org) and Board Member of the American Association of Naturopathic Physicians (www.naturopathic.org)
