ozelli, I would be positive you had such as drastic reduction in your PSA 11 weeks after treatment. This is the 3 month mark most are done at. I am told that it takes sometimes a year or more to get to the lowest mark you are going to get. Everyone is different in their recovery.

My PCP told me the prostrate is still pretty irritated after being radiated and thus they are looking for reduction after the tests. My oncologist/radiologist said the same think they are looking for reduction in PSA and only get concern if significant raise in PSA. I see from several posts that those who had hormone treatments and ADT their 3 month marks are lower than most who don't have ADT. Just my observation and don't know if medically means something.

You are correct PSA bounces are normal. Many things can cause the PSA bounce and not cancer so it is the test results over time. I am having my second one this week on Friday. I am just hoping for a reduction.

Remember watch what you do prior to test. I was told to not bike ride or have vigorous sex a week prior to test. The bike I understand as can cause prostrate irritation. I don't know why the vigorous sex is on there and what that means but I did not ask either.

Good Luck and let us know how you did!
