A member asked:

Is prostate-specific antigen (psa) used to monitor efficacy of therapy?

Yes: Psa is a method for monitoring a pt post treatment...After surgery psa should be at an undetectable level....If psa rises after any primary treatment this usually means cancer growth.

Yes: Psa is much more useful to monitor the response to treatment for prostate cancer than it is for diagnosis of cancer.
