It's quite a while since I’ve been active on the board....glad to see it's running strong – a great resource!
My story is in my signature. I'm 4 years past diagnosis and 3 /12 past follow up radiation. The lab my oncologist uses is does not run ultra sensitive tests, so <.1 is undectable on their test -- which it has been at my 6 months checkups. Today there was no "<", just .1.
My oncologist wasn't too worked up about that -- since I've already had surg and radiation, PSA has a long way to run before more treatment even IF it is on the rise...which is still an IF (this happened a few years ago to me, then slid back down to <.1).
Overall still a "good" checkup, but a little un-nerving.....anybody have any thoughts or experience similar to this? Thanks!

Nice to see you again.

Understand after all that time of beinb <.1, it would make me a bit nervous to see a .1

Your next PSA reading would be of great interest to me in your situation. If it rises again, then highly probable that you may have the start of recurrance again in your life. I certainly hope its not the case. Your next reading could just as easily be read again as <.1.

Not sure of your schedule this far out, but if it were me, I would want another reading no more than 3 months from this last one, even if that is sooner than your normal schedule.

Hopefully when its all said and done, you will be just fine.

Hi Sterd82,

I just noticed that you already had SRT, so I deleted my earlier post to you. Sorry to read about your possible PSA increase. Hopefully the missing "<" it just an oversight by the lab or a slight bump in your PSA and that you next PSA test result will again include the "<". Keep a close eye on your PSA level and get re-tested in 3 month or less.
All the best to you.
