Hi again,
In addition to all the good information zouzi provided, IF you are postmenopausal, there is a second drug, Evista, that has also been approved for
prevention of invasive
breast cancer. It is also used to reduce the risk
of spinal fractures related to osteoporosis, which is a plus for some women. (It was during studies of the use of Evista to treat osteoporosis that researchers noticed that among post-menopausal women who took the drug there was a lower rate of invasive breast cancer.
