@jeffmarc Did your source say what happens to the other 50% in that ten years? Did "none" of them need any treatment, and they died of other things during that ten years? I am sure that wrapped up in that 50% is a certain percentage of men who succumbed to prostate cancer vs those who got lucky and needed nothing before they died of something else. Man...that is a big "roll of the dice". Like you said about your brother, he got 6 years out of AS. I am sure that others get only 2-3 years, while others get 12-15 years. Such a strange disease.
