Breast Cancer Prevention: Double Mastectomy May Not Have Lasting Effects

Women diagnosed with breast cancer in one breast sometimes opt to remove both breasts through a double mastectomy as a preventative measure, but a new study finds that this may not be effective in increasing life expectancy.

Check out the video above from HealthDay TV that explains why this extreme surgery might not have the desired result — and the many reasons why women around the world still opt for it.
