Does Bicycle Riding Have An Impact On PSA Values?
Question:
I had a radical prostatectomy in 2013. My PSA has been <0.1 until 2013. Since then it keeps bouncing around as stated below. My Urologist is excellent and he feels that I have some begin tissue growing and not to worry. Of course I do worry and seem to have PSA anxiety logically so. What are your thoughts?? Also I am an avid cyclist and ride 200 miles plus a week. I have read that that could cause some PSA change.
Numbers and dates taken
1/13 <0.1
6/13 0.3
7/13 0.2
8/13 0.24
10/13 0.2
12/13 0.1
4/14 < 0.1
7/14 0.1
1/15 0.1
10/15 0.2
2/16 0.2
6/16 0.3

Brief Answer:
PSA levels have no relation to cycling.
Detailed Answer:
Hello XXXX and welcome to HCM.
As an Urologist,i can understand your concern.
The international protocol for checking PSA,after radical prostatectomy is as follows:
1. Every 3 months in the first year.
2. Then every 6 months,upto 15 years.
3. Further tests like bone scan,if there's rise in PSA more than 0.5.
4. PSA less than 0.2 is like zero.
PSA is not related to your cycling. It's very good exercise for you.
You're obviously following your Urologist's protocol, for PSA.
Your reports show,a fluctuating PSA. Repeat the next PSA after 6 months.
Wish you good health.

Thanks for the feedback Doctor. I understand the PSA is fluctuating PSA. Any idea why? Could it be begin tissue? Any other thoughts as to why??? Could the PSA drop again to <0.1 etc?
I meant to say benign tissue sorry

Brief Answer:
PSA below 0.2 is considered as zero.
Detailed Answer:
Hello XXXX,
Minimal fluctations below 0.2, are considered as 0.
So you don't have to worry there.
If the PSA touches 0.5, a bone scan must be done,to rule out a recurrence.
This also is a reason, for people to check for PSA once annually,for a lifetime.
I don't think there's any tissue left, that's causing the PSA to fluctuate.
These are normal levels,for all practical purposes.
A DRE or rectal examination by your Urologist,is also important in case of a rise.
Wish you well.
