Soy consumption reported to decrease breast cancer recurrence and mortality

In a study (published in December 2009) which examined women with a prior history of breast, the authors reported that soy food consumption (in an amount typically found in an Asian diet) was significantly associated with a decreased risk of death and breast cancer recurrence.
Importantly, these results did not vary based on the estrogen-receptor status of the tumor. This implies, that soy may be preventing breast cancer growth through an estrogen-independent mechanism. (read more here)
