I have not had my first PSA test after radiation (Proton) treatments. It was 3.75 prior to treatments. I am on of those individuals showing you can have prostrate cancer and still have a normal level PSA.

My Oncologist/Radiologist at UFPTI in my post treatment information stated the same thing about testing. That it should be at the same lab each time due to difference in labs which will affect the numbers. I am having my PSA test done at Mayo and my primary care doctor stated the same, to make sure I did each at same lab.

I am a little confused with some postings. What is considered a good PSA number after treatments. Is the first PSA after treatment not a good predictor of success or failure? Is the norm that your prostrate is still inflamed and irritated for the first PSA test which I assume is 3 months at most providers like mine is scheduled for.

I did read about biking. My primary care doctor and I were well informed about this as we thought my rise in PSA numbers was caused by bike riding as I was riding 25 miles couple of times a week. Then we did a plan not to ride 48 hours prior and then 72 hours. It went down a little first time but then rose again second time. It is then my primary care doctor referred me to Urologist.
