Everything depends upon your age and health at the time of discovery, family history of other medical issues etc. If you are 60 when diagnosed and most men in your family history live past 80, doing nothing would not be a good choice. If you are 67 and your father and his father died at 72 of a stroke, the decision is altogether different. In spite of all the hype about how aggressive prostate cancer is, my most recent urologist at a world renowned cancer center said it like this. You don't have aggressive cancer, you have active cancer. "On a scale of 0-100 with 100 being the most aggressive form of cancer, you are a 2!" He is fully aware of 2 MRI's, a biopsy 4+3 gleason, Decipher Score or .84. "Whatever treatment plan we come up with, we are treating what is going to happen 10 years from now!" I wish the 3 other urologists and the oncologist I saw before him had explained it that way.
