It might be worthwhile recording your consultation on your phone, (with the permission of those present). Many men are in shock and a lot of the conversation goes over their head.
They helpfully gave me a CD recording of my diagnosis consultation, which I have never listened to as I already twigged I had PCa, so the consultation came as no shock at all.
I wouldn’t waste my time and money on any DNA quackery if I were you. I am part of a trial at the Royal Marsden to establish if there is a genetic link, but as no other male members of my family had PCa and are all dead, I fear my input won’t be of much use to the rearchers.
Best of luck.
Cheers, John
