"High serum levels of testosterone and estradiol, the bioavailability of which may be increased by Western dietary habits, seem to be important risk factors for postmenopausal breast cancer."

I just want to point out that this article is specifically addressingl postmenopausal bc risk. A word of caution here, when I was at the Memorial Sloan Kettering for cancer care, the nutritionist said to avoid vit. E as it was a blood thinner and there was some concerns that blood thinners would enhance cancer metastasis. So I definately wouldn't over do it on fish oil, with its blood thinning properties.
