I saw this article the other day. 3 years too late.
I was Gleason 3 + 4 = 7 with a PSA over 10, but my urology team was itching to do surgery. More lucrative I guess.
I was Gleason 7 also and they said it was so fast growing it would kill me quickly.
Had it killed (ablated) with Tulsa-PRO (Trans Urethral Ultrasound Ablation), a non-invasive procedure being used more and more today. 3 years ago - all is well, all functions normally. No pain or discomfort.
