PSA at 3 months after radiation: Should it be lower?

Posted by giordi @giordi, Apr 9 5:09pm

PSA about 11.0 before Proton Beam radiation. Received 44 treatments. Now 3 months later PSA is 5.81. Should be lower?

I received 5 high dose proton radiation and 3 shots of adt, will be a year next month. My psa was around 6, Gleason 4+3/7 intermediate. So to date I’ve had 3 psa tests and my results were; .17, .19 and .23. My doctors are happy where I’m at. As to what it would be without adt, I don’t know. But so far, other than them not being clear on what should happen, I’m progressing well. The adt was a real bitch and I’m still having side effects from them, much diminished but they are there. Do your research and ask your team members about it. Good luck, my brother.

2010 2.5 months at Loma Linda for proton radiation therapy (the time currently with new procedures is much shorter). Gleason 3 plus 3; pre-proton PSA 6.47. Slow growth prostate cancer. As 2015, PSA at .1 or .2. then PSA began to rise to currently 3.49. The question is either a return of cancer or just normal growth or recovery? No one seems to know.

So, every six months a PSA blood test to determine the growth/change in PSA.

I use the VA system even though have TriCare For Life as retired Army Officer. I also did contact Mayo in Jacksonville for sometime in the future review and 2nd opinion.

If anyone has a very similar situation, please chime in. Thanks/Leesbur, Florida


With radiation treatment, it takes time. Your prostate was burned with radiation and is slowly going away. It will eventually stop, or nearly stop, producing antigens (the A in PSA). You just monitor it with a blood test every six months to watch if slowly go away.
