Hmmm.... This article seems to indicate it may be a ZINC issue and too much zinc favors cancer.

Also blocking zinc transporters may be beneficial in aggressive forms of breast cancer

Yep, we do NOT want zinc transported!

and inhibiting the CK2 seems effective for other cancers

CK2 expression is 10 fold higher in breast cancer

I"m on a roll now! Found this little gem as a way to inhibit CK2 (CK2 upregulates transfer of Zn) Coumestrol inhibits CK2 But it also acts as a phytoestrogen, natural compounds that mimic the biological activity of estrogens
http://www.ncbi.nlm.nih.gov/pubmed/23845105
and it appears red clover is highest in Coumestrol
https://en.wikipedia.org/wiki/Coumestrol
Now I am more than intrigued!

"A specific dietary supplement, selected vegetables (SV), which contains coumestrol, was studied in tumor-bearing mice and in stage IIIB and IV non-small cell lung cancer patients [
37]. The study found 53-74% inhibition of tumor growth in mice, but more strikingly, patients in stage IIIB and IV NSCLC who took SV daily for 2–46 months had prolonged survival and attenuation of the normal pattern of progression compared to patients not taking SV [
38]."
In case you are wondering the SV in the above quote was the following: 63 mg of inositol hexaphosphate, 4.4 mg of daidzein, 2.6 mg of genistein, and 16 mg of coumestrol
WOW, get a load of this pilot study!
