Women taking supplements containing isoflavones may have a lower risk
of breast cancer, with high content supplements consistently linked
with reduced risk.
Women who used supplements containing isoflavones, including soy, red clover, garlic, and evening primrose, for a period of at least five years were at a 25% lower risk of breast cancer.
«Our findings suggest isoflavones supplements are associated with reduced postmenopausal breast cancer risk,» wrote the researchers.
Results suggested that women who took high isoflavone content supplements, a consistent and significant reduction in breast cancer risk was observed (28% risk reduction), and the risk decreased further for longer term use (43% risk reduction when used for one to five years).
