Wait for the MRI before doing anything. Although surgery, especially robotic, is perhaps better than what I had 21 years ago, I would avoid it. Have you had a second opinion? Has anyone suggested watchful waiting? If you’re cancer is truly Gleason 6, I wouldn’t think you have much to worry about. If you do treat, highly focused radiation guided by the MRI would be the way to go. But I am not a doctor. I’m just a guy who wishes he had an option to surgery when he was first diagnosed. Best of luck.
