   After prostatectomy, PSA levels drop rapidly, reaching very low or undetectable levels within two months. Radiotherapy also substantially reduces PSA levels, but more slowly and less completely, with PSA levels reaching their nadir two years after radiotherapy. [53] After either treatment, PSA levels are monitored regularly.

   After surgery or radiation therapy, PSA may start to rise again, which is called biochemical recurrence if a certain threshold is met in PSA levels (typically 0.1 or 0.2 ng/ml for surgery). At 10 years of follow-up after surgery, there is an overall risk of biochemical recurrence of 30–50%, depending on the initial risk state, and salvage ...
