You call me "stupid" yet you spell "rid" using the letters "reed".
As a prostate cancer survivor, I feel I know a little about the potential of HIFU. I had robotic laproscospic prostatectomy surgery a year ago, but HIFU is another alternative being used--- successfully--throughout much of the world for certain low grade cancers and for those unable or unwilling to have hormone treatments or surgery.
Have a good day. (Consult your urologist about the POTENTIAL of Hifu).
