Ok guys the doctors are baffled but I have a question. First a little back ground on the progress of my disease. In Nov of 2015psa jumped from .9 to 3.7 after starting casadex I was sent to med onc. Rejected not high enough. Jan 2016 psa 470 this time the med onc took me. Bone scans showed bone lesions from head to feet to many to count. Ct scan showed nodules in the lungs. Mar 2016 psa over 2000 reason stated like that is military hospital test only accurate to 2000 but test measured way higher. Had port put in and was started on zometa and taxotere. Was just released from chemo with a psa of 1.8 and bone lesions less active and smaller in size. Lung nodules stable and not growing. Now the doctor wants to start me on Xtandi with the Lupron I have been taking for 3 years. Does it seem to early or am I just paranoid about the disease come back full blown. Just looking for opinions and to try to make me feel better about the change. I do not want to be on my death bed this earlier again. Pretty much wrote off by 3 doctors back in Mar 2016 with weeks to live. Guessed I fooled them. Thank you for all responses.
