Firstly I am not a medical professional. But having looked at reputable sources of information regarding this on cancer websites; I see it is a food supplement and there is no evidence that it will replace a drug such as Tamoxifen. It seems that it is taken with and not instead of professionally prescribed drugs.

Your consultant or oncologist is your best source of professional knowledge.

Hi Kirsteen78. I don't really know anything about this supplement but my oncologist has warned me against taking most supplements, other than the basic calcium, magnesium and Vitamin D. To be quite frank, I don't like the sound of it. 

May I suggest that you post your question in the Ask a Nurse section of this site. Ellen or one of the other nurses would be best placed to answer your question properly.

Hi Kersteen

I’m afraid I don’t know anything about that supplement but reading the info you posted I don’t think I’d take it in the hope that it might do the same thing as tamoxifen (I am on tamoxifen so have done some research). 

As someone has said you could ask the nurse on here or even call your breast care nurse and they could speak to your consultant??

Hopefully you’ll find something, take care x

Hi Kirsteen78,

I've spoken to our nurses about this, and John has replied:

Hi Kirsteen,

There isn’t enough evidence to demonstrate that DIM supplements would be beneficial. The WebMD information you posted suggests that there’s a risk that this supplement may actually be harmful in oestrogen receptor positive breast cancer – again the evidence is limited for this. If you are researching a natural approach you could consider seeing a homeopathic doctor. The British Homeopathic Association has a searchable database. MSKCC.org is another useful resource for researching herbs and botanicals. As other posters have mentioned always discuss any supplements you plan to take with your healthcare team first.

Best wishes,

I hope this helps. Let me know if you've got any questions as I'm happy to follow up.

Best wishes,

I know this is an old thread, but a valuable question. DIM or diindoylylmethane derived from cruciferous vegetables breaks down good estrogen instead of the bad estrogen. It acts as an aramotase inhibitor and stops testosterone converting into estrogen and also acts by detoxifying estrogen through the liver. I've done quite a bit of research into it, but by No means am I medically qualified so don't quote me. 

Interesting to see the webmd article, there are women out there taking DIM to reduce estrogen dominance. I would always ask my oncologist before taking anything extra. 

I'm on tamoxifen and am also interested in DIM. But will not take it until spoken to a professional.

It would however, be interesting to see if any of you ladies or men have been taking DIM and have been advised to.
