Hi, Brian: I am not sure if I answered all your questions the other day. They are using target radiation for the lymph nodes and the cancer in the prostate. They said there is no need for genetic testing because, although his father had prostate cancer, he didn't develop it until perhaps the age of 70. (My husband is 69). The oncologist said it would be different if his father had developed it at 40 or 50. As well, he said there is not an indication of a need for the spacer because he has no bowel issues.... and he would have had to be sent to a city 4 hours away for that process. I will try to look up the Novartis PSMAddition to see if I can learn anything. I really don't feel that he should be on hormone therapy forever. That seems like a life sentence. I am encouraging him to do the weights and he has started doing that every other day. That makes me feel happy (for him and for me). I have found that there is another second generation drug, an option to abariterone which has fewer side effects. When we meet with the doctors this week, I am going to ask about it. I have found a site PCRI.org which specializes in prostate cancer and the doctor Mark Scholz seems so knowledgeable. I watch their videos daily. I am so thankful that there are people out there, like yourself, and others, who are willing to share what they know so that we don't feel as though we are all alone. Our cancer centre is brand new and is supposed to be state of the art but I feel, being a Canadian hospital, it still cannot measure up to what you have in the States.
