Eating a Breast Cancer Preventive Diet
If you have read any breast cancer prevention articles over the last month, you probably saw several articles on making sure your diet includes plenty of omega-3 fats as well as high antioxidant-containing foods like berries, colorful vegetables, beans/legumes, and green tea — all to help your body keep damage from free radicals to a minimum.

Most breast cancer is the type that is called hormone sensitive. That means it is cancer that forms in response to estrogen. It is usually implied that it is solely a matter of having too much estrogen (and/or other compounds that have estrogen-like structure) in the body. However if you dig deeper, you learn that it is not so much the estrogen itself, but how it is being metabolized in the body and whether it is balanced by adequate progesterone that are the primary problems.1-2

The balance between estrogen and progesterone is very important for breast health and is almost never mentioned in popular literature on hormone sensitive breast cancer. There is a big misunderstanding among some people in the medical community that progesterone increases breast cancer risk. This was due to studies that found that synthetic progestins formerly used in women on hormone replacement therapy did increase breast cancer risk. However, further study has clarified that natural progesterones do not.3
