There is a new trend in women who are deemed to be at high risk for breast cancer to have a prophylactic bilateral mastectomy. A mastectomy is not minor surgery and comes with its own set of risks. Women who then want reconstruction can be faced with months of additional surgery as well as the issue of implant replacement later in life. Other side effects can linger such as lymphedema for a lifetime.
A new government task force (who is spending our money on these things) announced that high risk women should consider taking either tamoxifen or raloxifene to reduce their risk. While the drugs carry their own risks, they also can be stopped. A mastectomy is irreversible.
I realize this is a very personal decision and emotions can rule the decision making process. Perhaps this study will help women not make such a drastic step.
