Hi john
I've read through your posts for the first time today. Both my father and my husband have prostate cancer- my husband caught his early last year (through no help of the GP, who had a high blood test for six months and did nothing about it), my father did not. My dad was diagnosed with local spread in 2001, and is still fit and healthy.
Something that has struck me about your post. One thing that both my brother did when my father was diagnosed, and my husband's brothers did when he was diagnosed was to go and get tested. Immediately. I know you have other things on your plate, but with your history I would Insist on a yearly blood test. Pay for it if you have to, but with your family history I'm sure they will see the sense.
