My doctor told me my PSA had gone down to 0.1. Is this possible to go from a PSA of 6.7 before treatment and 0.1 after 43 treatments.I also had one shot of Lupron approx. 90 days prior to treatments began.


The PSA drop to 0.1 ng/ml is very reasonable in your case. However, it is likely this decline reflects the impact of the Lupron as well as the radiation therapy. You will gain a clearer picture as your testosterone recovers. Depending on how aggressive your cancer is, at my clinic, AIDP, we would normally do blood tests every month or every three months. We would measure PSA, testosterone, dihydrotestosterone and 25-hydroxyvitamin D.
