Can Medications Prevent Breast Cancer?
A new study in the journal the Lancet looks at how effective common drugs are at preventing breast cancer.
Researchers discovered women taking drugs including Tamoxifen and Raloxifene were 38 percent less likely to develop the most common type of breast cancer than those given a placebo.
The reduced risk extended at least five years after stopping treatment.
Some women are hesitant to take the drugs because of possible side effects including a greater risk of developing blood clots and endometrial cancer.
