The drug tamoxifen is used to treat breast cancer, but it's also been found to reduce the risk of developing invasive breast cancer by 50 percent. However, its side effects include the possiblity of uterine cancer and blood clots.
But a double-blind study of the drug raloxifene, sponsored by the National Cancer Institute, demonstrated an equally effective remedy for invasive breast cancer with diminished side effects.
According to Dr. Ana Maria Lopez of the Arizona Cancer Institute, the availability of raloxifene offers women not only an alternative, but more options for their care.
