@jeffmarc I've seen others, though I can't remember where, quoting about a 1 in 1000 men who have IMRT / SBRT get another cancer. In any case, Brachy is almost exclusively hitting only the prostate will little over spray. IMRT / SBRT must pass through normal tissue to get to the prostate. We know that the prostate can withstand radiation at much higher doses than normal tissue. That's another reason why I think Brachy, either LDR or HDR, is the best choice. It's not practised as much here because it takes more effort and doesn't pay nearly as well as other modalities of treatment. Mark Sholtz has a segment about that aspect also.
