@jaflag Totally get your concern and understand your need to be proactive with BRCA2.
However, I posted an article today (NEW BLOOD TEST) and in it you can find links to other Duke studies; one of them had a short blurb about BRCA2 and how it relates to PCa.
New to me was the fact that not all men with BRCA2 go on to have the most aggressive cancers - many do not.
So perhaps that new blood test at Duke which tests for future castrate resistance/poor prognosis is the one you need to see how aggressive you need to be with your treatment. Hope that helps,
