Decided to track the history of my "metastasis" diagnoses 15 years ago. Yes, there was suspicious evidence of an enlarged lymph node by CT and maybe by Prostascint. So every few years my oncologist sent me for a CT and a Tc Bone scan. HOWEVER, when I look at those scans I see they were always (but one) scheduled for a time when my psa was at minimum (<0.1)! Sure, the lymph node was never visible at those times. dUH!! Fortunately, there was ONE CT at a higher psa and that too confirmed that the lymph node issue "had resolved". But six scans a total waste of money, time and X-ray exposure. Am I angry? You bet!
