Prostate Cancer - Radiotherapy vs Robotic removal of prostate

I have been on Cancer watch fro a few years, being a 6 on the Gleason scale,  however, after a biopsy my Gleason score has gone to a 7.  I was called in to see, firstly, a  surgical registrar who talked me through the advantages and disadvantages of a robot removing my prostate completely.  I went home to ruminate over this and was back at Urology a couple of days later.  This time I saw the Radiology Consultant.  He went through the pros and cons of radiotherapy for my prostate cancer.  He asked me what I thought and I told him I would rather have the prostate removed once and for all and being 69 an erection was the least of my worries.  He asked me to wait a few moments and then in came the Surgical Consultant.  He went over what his registrar had told me and I said I wanted to go to the Christie Hospital for Robbie the Robot to do his business.  I was told I would have to come back in a couple of weeks to see the Oncology panel which would have the registrar in charge of the robot at the Christie Hospital and that it would be his decision.  What about my decision?  Does that not matter?  Some women, even if they do not have breast cancer can have mastectomies to ensure they do not get breast cancer.  Here I am with diagnosed with prostate cancer and I have to wait to see if I can have my prostate removed or face waiting even longer , hoping the cancer does not progress.  Where is the justice in the treatment lottery.
