God bless you Rusty. Before I retired, the average age of my work group (70 old farts) was 65 and many had endured prostate cancer, heart attacks, and we lost one to Alzheimer's. ALL of the prostate guys came through it, only 2 had radical surgery and the rest had the implants. 2-3 had similar experience as you are having, with bad or negligent diagnoses, but they made it fine. Write letters to anyone you can find that will jump on the VA. My son was in a bad motorcycle accident 2 years ago and the VA would not help because he was on a long list. I called my Congressman, who was a Veterans advocate, and he helped but the bureaucracy was still pitiful.
I'll pray for you Brother, keep the faith,
Steve
