Evaluation of the synergistic effect of insulin resistance and insulin-like growth factors on the risk of breast carcinoma. Cancer. 2004 Feb 15;100(4):694-700. "The results of the current study suggest that insulin resistance and IGFs may synergistically increase the risk of breast carcinoma."
Dietary glycemic index and glycemic load, and breast cancer risk: a case-control study. Ann Oncol. 2001 Nov;12(11):1533-8. Direct associations with breast cancer risk emerged for glycemic index and glycemic load. High glycemic index foods, such as white bread, increased the risk of breast cancer (OR = 1.3) while the intake of pasta, a medium glycemic index food, seemed to have no influence (OR = 1.0). Findings were consistent across different strata of menopausal status, alcohol intake, and physical activity level.

Dietary glycemic load and breast cancer risk in the Women's Health Study. Cancer Epidemiol Biomarkers Prev. 2004 Jan;13(1):65-70. "Although we did not find evidence that a high glycemic diet increases overall breast cancer risk, the increase in risk in premenopausal women with low levels of physical activity suggests the possibility that the effects of a high glycemic diet may be modified by lifestyle and hormonal factors."
Premenopausal dietary carbohydrate, glycemic index, glycemic load, and fiber in relation to risk of breast cancer. Cancer Epidemiol Biomarkers Prev. 2003 Nov;12(11 Pt 1):1153-8. In this study lean (premenopausal) women had lower risk or breast cancer the more carbohydrates they ate, whereas overweight women had higher risk the more carbohydrates they ate. Also study found no association between fiber intake and breast cancer risk.
Energy sources and risk of cancer of the breast and colon-rectum in Italy. Adv Exp Med Biol. 1999;472:51-5. In this study, high intake of starch, and saturated fat were linked with an increase risk of cancer. High intakes of polyunsaturated fatty acids (chiefly derived from olive and seed oils) were protective for breast cancer.
Dietary glycemic index, glycemic load, and risk of incident breast cancer in postmenopausal women. Cancer Epidemiol Biomarkers Prev. 2003 Jun;12(6):573-7. Dietary glycemic index and load were not associated with increased risk of postmenopausal breast cancer after adjustment for multiple breast cancer risk factors.
Omega-3 fatty acids
Long-chain n-3-to-n-6 polyunsaturated fatty acid ratios in breast adipose tissue from women with and without breast cancer. Nutr Cancer. 2002;42(2):180-5. "We conclude that total n-6 PUFAs may be contributing to the high risk of breast cancer in the United States and that LC n-3 PUFAs, derived from fish oils, may have a protective effect."
Opposing effects of dietary n-3 and n-6 fatty acids on mammary carcinogenesis: The Singapore Chinese Health Study. Br J Cancer. 2003 Nov 3;89(9):1686-92. "...high levels of dietary n-3 fatty acids from fish/shellfish (marine n-3 fatty acids) were significantly associated with reduced risk." Also, women consuming little omega-3 fatty acids and lots of omega-6 fatty acids had a higher risk of breast cancer.
Regulation of tumor angiogenesis by dietary fatty acids and eicosanoids. Nutr Cancer. 2000;37(2):119-27. "High-fat, n-6 fatty acid-rich diets were associated with a relatively poor prognosis in breast cancer patients; in a nude mouse model the same diet enhanced breast cancer progression, whereas n-3 fatty acids exerted suppressive effects that were associated with impaired angiogenesis."
N-3 and N-6 fatty acids in breast adipose tissue and relative risk of breast cancer in a case-control study in Tours, France. Int J Cancer. 2002 Mar 1;98(1):78-83. "We found inverse associations between breast cancer-risk and n-3 fatty acid levels in breast adipose tissue."

Multifunctional aspects of the action of indole-3-carbinol as an antitumor agent. Ann N Y Acad Sci. 1999;889:204-13. Indole-3-carbinol, a compound found in cruciferous vegetables, decreases the carsinogenic form of estrogen and increases the protective form.

Does Vitamin E Prevent Breast Cancer? LE Magazine May 2002 In-depth coverage based on reviewing the scientific studies made about vitamin E and breast cancer. Evidence points to the form of vitamin E called tocotrienols as effective in preventing breast cancer - and not alpha-tocopherol (the one commonly available as a supplement).
Vitamin E and breast cancer prevention: current status and future potential. J Mammary Gland Biol Neoplasia. 2003 Jan;8(1):91-102. "Recent reviews of epidemiological data suggest that dietary source vitamin E may provide some protection against breast cancer, while vitamin E supplements do not."
The inhibition of the estrogenic effects of pesticides and environmental chemicals by curcumin and isoflavonoids. Environ Health Perspect 1998 Dec;106(12):807-12. "A combination of curcumin and isoflavonoids was able to inhibit the induced growth of ER-positive cells up to 95%. ...a mixture of curcumin and isoflavonoids is the most potent inhibitor against the growth of human breast tumor cells."
Effects of soy phytoestrogens genistein and daidzein on breast cancer growth. 1: Ann Pharmacother. 2001 Sep;35(9):1118-21. "Genistein and daidzein at low concentrations were found to stimulate breast tumor growth in in vitro and in vivo animal studies, and antagonize the antitumor effect of tamoxifen in vitro. At high concentrations, genistein inhibited tumor growth and enhanced the effect of tamoxifen in vitro."
Genotoxic activity of four metabolites of the soy isoflavone daidzein. Mutat Res. 2003 Dec 9;542(1-2):43-8. Thus, both reductive and oxidative metabolites of the soy isoflavone daidzein exhibit genotoxic (damaging to DNA) potential in vitro.
Combined inhibition of estrogen-dependent human breast carcinoma by soy and tea bioactive components in mice. Int J Cancer. 2004 Jan 1;108(1):8-14. This study found that soy and green tea inhibited breast cancer growth, and that that the combination of them two was even better, reducing tumor weight by 72%.

Lancet. 2002 Jul 20;360(9328):187-95. "The longer women breast feed the more they are protected against breast cancer. The lack of or short lifetime duration of breastfeeding typical of women in developed countries makes a major contribution to the high incidence of breast cancer in these countries."
