Just sharing my experience. My prostate was removed about 15 months ago. Although my nodes were clear I had positive margins with a Gleason = 8. I was continent a few months after surgery but have been dealing with an overactive bladder since (although it was slowly getting better and certainly manageable after physical therapy, bladder training, avoiding certain foods, etc.)
The PSA testing here has a detectable level of 0.02, and my levels for the next several months were non-detectible (less than 0.02). However, about 1 year after surgery my PSA jumped to 0.08 My urologist wanted another PSA 1 month later just to confirm. This time it was 0.11, so he referred me to the Cancer Agency. 2 months after that (mid October) it was 0.12
I had a CT scan and Bone scan to see if the cancer had spread beyond the prostate bed (then later an MRI to check my lower back). These were clear, so I was put in line for salvage treatment for the prostate bed (and surrounding nodes) which involves 6 months on hormone therapy (started mid Nov), and radiation treatment (started mid December).
So far I have been zapped 15 times (a treatment every working day) with 18 more to go (33 in all). The side effects are becoming more apparent (for me it has been urgent/frequent voiding, diarrhea, and nausea/fatigue - meds help with these). As I understand the side effects increase with more zapping, then they start to decrease a couple of weeks after the last treatment and hopefully after a while, things will eventually return to normal.
Anyways, your numbers are still low - certainly below the non-detectable level used for my PSA testing. What is the non-detectable level for your PSA testing? I believe the non-detect level is essentially the margin of error associated with the number, so a change from 0.007 to .01 may still be within the realm of uncertainty for the method used for PSA testing.
But check with your urologist to find out the meaning and significance of both the numbers and the trend. They may want to re-do the test to confirm whether the increase is real or not.
Hope this helps.
