Just what I wanted to know, thanks.
This back pain thing is described in a paper about natural chemicals/foods aiding the battle. Again, it seems that Asian men are nowhere near as likely to be affected by prostate cancer. To my surprise, curcumin is again (my thread on Alzheimer's and Parkinson's ) considered to be a major factor.
I have been offered treatment on a HIFU machine outside the US., but they want to shrink my 49cc down to below 40 with hormones -- to reduce the distance for the focal point of the energy to reach the middle.
It seems that the later generation of $700,000 machines can 'see' with added clarity in the work-space, but it still does not give me any confidence in the containment of the disease. My feelings at this time are to go with the full procedure at home.
