Tulsa Pro can do multiple spots in case you were wondering. Some academic places doing Tulsa are taking 3+4 single spots but only to keep it simple and get publications out the door, you may have to go to one of the non-academic Tulsa places like I did, see my link I posted earlier. Try to stay calm and use meditation or contemplation practices so you can work on it as needed because there is a lot usually to read and think about. I had a lot of your fears too, and Tulsa was the right one to go to. I also had a spot on kidney too that was not prostate cancer but I had ablated a year before I did Tulsa.
