Cyberknife-SBRT-first PSA results ??

Hello Friends,just got my PSA results, 3 months after my 5 sessions of CK SBRT,which ended March 14th,2016.As my signature reads 2-16-16 PSA was 6.89 (baseline).This first draw was 3.69 on 6-29-16,thats almost half less than baseline.Another CK brother had a baseline of 6.1 PSA.After his first draw PSA was down to 1.9.

I just came back from a 3 week cross country driving vacation with Wife and dog.Got home,the next day had to cut 1 acre of grass on my lawn tractor,its a little bumpy and the following day had my PSA draw.Also had intimacy with my Wife exactly 3 days before the PSA.I will not see my RO till July 12 th.I use a local hospital for lab work and they fax the results to her and they mail me a copy.

Should I be concerned that my PSA was not lower,or is a individual thing as far or where the PSA is at 3 month out ? Could my activities have given me a higher reading than I expected?

Hoping to hear from my CyberKnife,SBRT Brothers.Happy belated 4th,of July.SemperFi

Hey Nomar,I am not on Lupron,or anything else.Just had the 5 Zaps of SBRT.

Congratulations! Absolutely no need for concern. A drop by half at 3 months is very typical. Slower rates of decline and bumps along the way are actually associated with better outcomes. Guys who have more sex sometimes have more bumps too.

0311, I had SBRT about the same time as you, ending 3/4. My baseline was 5.66, dropping to 2.38 on 6/15...so I'm on track also. As the others suggest, I doubt any single reading means much.
