Surgeons are using a high-powered beam of ultrasound to treat prostate cancer because its precision can destroy the tumor without killing off surrounding tissues. The reason this is so important is because if it spares the nerves that are critical for male sexual function then there is no impotence. Regular treatments that we use now leave half of men impotent and a fifth incontinent. This is exciting news. One of the men treated stated, "It is amazing that the power of sound treated my cancer without any impotence or incontinence. Of course when I came home and heard my wife nagging at me I realized that the power of sound can also reverse all of this as I immediately became impotent....and incontinent". *
*Editor's note: I totally made that last part up to get a cheap laugh and that was wrong. I am going to hear it from my wife about that one.
