Soy May Prevent Breast Cancer, Study Finds
(Washington, Reuters, April 5, 2006)

Leena Hilakivi-Clarke of Georgetown University and colleagues at Georgetown in Washington and Johns Hopkins University in Baltimore reviewed 18 separate studies of soy and breast cancer. The investigators concluded that Causcasian women who ate soy had a 14% reduction in breast cancer risk, but the researchers did not determine whether the benefit came from the soy or from other healthful habits; nor whether taking supplements has the same effect as eating actual soy foods. Scientists speculate that the isolflavones in soy may promote the destruction of malignant cells by blocking estrogens.
