It is my hypothesis (1994) that low DHEA may cause breast cancer and other
cancers (Annals of Internal Medicine 2005; 142: 471-472). Furthermore, in
1997 I explained that the positive effects of soy on breast cancer may be
due to soy increasing DHEA levels
(
http://www.anthropogeny.com/Soy%20Products%20and%20Breast%20Cancer.htm ).
I suggest the findings of Shu, et al., (JAMA. 2009;302(22):2437-2443) may
represent the ability of soy to increase DHEA levels.
