The hormonal therapy is used in conjunction with radiation to improve the chances of killing the cancer cells especially in the area of limph nodes, where they cannot deliver high radiation dozes. I am on the same protocol, but as a salvage not adjuvant treatment.
I believe you first start Casodex to prevent "flair" (rise in testosterone level that may cause rapid cancer growth), then you get the shot (Lupron in my case).
I would suggest to look for another doc that you can talk to. Get a couple of opinions. Talk to radiation oncologists. Get a copy of your pathology report and read it yourself, dont let them interpret it for you. You have to do your due diligence first. Go with the doc you feel comfortable with, can talk to, who explins things to you and does not push.
