Thanks for the feedback. As I was reading the notes I began thinking about what a lower PSA means. I realize that a high PSA is a strong indicator of cancer so does this mean that a low PSA is an indicator that there is no longer any cancer? This seems logical but is it?

erkbiz, if you have a prostrate you probably will show PSA.
When I started radiation treatment I was within the normal range for PSA. So having a lower PSA does not mean you do not have cancer nor does a higher PSA indicate you do.
When you have surgery to remove prostrate the PSA should eventually go to undetectable range and stay there. If it starts to rise it indicates cancer is still within body. If you did not have prostrate removal surgery many things can cause a PSA to rise and not be cancer.
What my radiologist/oncologist and primary care doctor stated is that once it goes down to a stable level (they want it to be below 1) they monitor a rise in PSA levels. If it rises it can be two reasons (non cancer prostrate issues) or cancer. PSA is only made in prostrate and prostrate cancer cells.
There are some good research sites you can investigate that get into PSA levels after surgery and radiation treatments. It is the rising PSA that is concern that needs to be check to determine in prostrate issues or cancer causing it to rise.
