A new study indicates that a double mastectomy reduces the risk of breast cancer by 90 percent. (And ladies, throw out a couple of ovaries and your odds are another 5 percent improved.) How extraordinary. Following this logic, I'd like to see a study on testicular and penile cancer and what they recommend cutting off to reduce the risk there. Want to bet we'll never see a study that suggests cutting off someone's penis if they're in a "high risk" penile cancer group? I know it's a sucker's bet any way you look at it. Better yet, how about cutting off someone's head to reduce the risk of brain cancer? Or who needs a pair of lungs? Absurb? You bet. But no more outrageous than this study. Is this really what medical researchers do?
