@davinik David D, after 2 years and 4 months, my PSA is still <.01, next blood draw will be in April. Downside is an incredable shrinking penis and zero sexual drive. But given that I'm 75 and considering the alternative I'm fine with it. The original reason for picking radiation over an operation is the fear of incontinence like you. If I had to choose it again, I would go with the 5 treatments over 10 days again. Good luck!
