Hi Dalota. Sometimes it takes quite a few data points to determine whether you are just fluctuating or a fluctuating but gradually increasing. Remember: there is uncertainty in the right-most digit of any lab test. If you were to draw your blood today and repeat the PSA test you had 20 times on your same, I doubt that all 20 would come back with the same digit. You might see that while most were, say, 0.06, one or two might be 0.05 or 0.07. That's the nature of testing. Also, our PSA probably varies from day to day or week to week; I believe early testing when PSA was discovered showed that our PSA fluctuates.
Men who might need to start SRT between 0.1 and 0.2 are likely those who are within a few years from the surgery or have some high-risk factors (high Gleason score, adverse path findings such as seminal vesicle invasion and/or positive margins, etc.).
There is less urgency when a man is a good number of years out from surgery and the PSA is climbing slowly. I suggest that if you continue to worry, you switch to the Labcorp ultrasensitive PSA test, which has three digits after the decimal point:
it lets you worry in greater detail In other words, you'll probably realize that your fluctuations are smaller than you think.
IMO you have plenty of time to monitor your PSA. Should you reach a confirmed 0.1, you can talk to your uro about
a consult with an R.O. Can you provide you salient history (especially the pathology results after your RP: Gleason score pT staging, and any adverse findings like positive surgical margins), preferably in a signature file that gets added to all your posts, so you don't have to keep typing it and other Forum members wanting to answer your questions have this information. Thanks!
