Women
with an elevated risk of developing breast cancer have the option of taking
tamoxifen, a drug that has been shown to have cancer-preventive effects in
these women. But the prevention isn’t complete, and like most drugs, tamoxifen
carries a risk of side effects.
New findings from a large trial indicate that breast density measurements
obtained from routine mammograms can reveal within a year or so whether taking
tamoxifen as a preventive is worthwhile for a woman. Jack
