NCIt definition : A dietary supplement isolated from soybeans containing phytoestrogen isoflavones.
Although the mechanism of action is unclear, soy isoflavones mimic estrogen action
mediated through estrogen receptors. In addition, this agent also modulates estrogen
metabolism. As a result, soy isoflavones have been shown to reduce tumor cell proliferation
and induce tumor cell apoptosis, as well as to be able to regulate hormone balance
and reduce the risks of breast cancer, heart disease, and osteoporosis.;
