Rebound PSA after Cyberknife Radiation Treatment

Please relate your experience with Rebound PSA.
Personal: Cyberknife Radiation May 2013 - PSA 10.7
One month blood test - PSA 4.8
Three month blood test - PSA 6.6
Six month blood test - PSA 7.1
Urologist says rebound not uncommon.

Doesn't look like a bounce to me. Psa should be decreasing then an uptick in a year or two would be considered a bounce. Two continuous rises from nadir is considered a reoccurrance for radiation; I would expect cyberknife to follow a pattern similar to other radiation modalities. Never mind your urologist; what does your RO say about this? he would have much more experience in psa activity after cyberknife.

My PSA level was 3.6 @ diagnosis 04/12.

Had BT 07/12.

3 month check-up PSA was 6.2.

6 month check up (last week)- PSA was 3.2.

URO and RO and MO have told me initial jump is not uncommon.

All my MD's also told me PSA nadir may take up to 24 months.

Hope this helps.
