Re: Cycling and PSA results

Got another PSA yesterday, 5.0. I decided to go ahead and schedule a biopsy in October even though my urologist is still comfortable with just watching the PSA over the next few months. The MRI report indicates the possibility of low-grade cancer but I am concerned about the subjectivity of these reports. What if it's the beginning of aggressive cancer? My uro says aggressive cancer will have a high Gleason early on, but the MRI images should reflect this aggressive nature.
Your thoughts would be appreciated.

Hi Jerry,

I would consider finding another urologist. Any uro that has a patient with a PSA of 5.0, and advises to wait a few more months, is someone to run away from.

While it does not fall into the normal category, it IS VERY possible for such a PSA number to be associated with more aggressive prostate cancer. In fact, I've seen at least one other person who turned up with prostate cancer even with a PSA of UNDER 1.0.

I don't recall if this case involved a higher Gleason score or not, but that is also possible.

I don't recall from the earlier part of this thread, but do you have BPH? If so, that could also be an explanation for your 5.0. But that still does not rule out the possibility of having a tumor at the same time. Two uros urged me to have a biopsy with a PSA similar to yours, and I refused -- until my number went up a couple notches.

Turned out that I DID have prostate cancer all along. Fortunately, it was Gleason 6.

I would suggest that you do need to have a biopsy. If you do, best to make sure the uro has a lot of experience and a good track record/reputation.

Good luck!

Re: Cycling and PSA results

MRI Fusion Biopsy results were negative for cancer. 16 cores were taken with 4 cores targeting the small spot noticed on the MRI. Will get PSA's every three months for now. If PSA continues to rise a second MRI will be done followed by biopsy.
Thanks again for all your comments. I read many of the stories which were a tremendous help in calming my nerves.

Re: Cycling and PSA results

Hello,

You are correct about the bicycling, masturbating, etc., prior to the PSA blood draw.

Basically, the preparation for a PSA test includes the following:

IN THE 48-72 HOURS BEFORE THE TEST:
* Do NOT have any kind of sex
* Do NOT ride a bike
* Do NOT perform any strenuous exercise
* Do NOT have a digital rectal exam performed

All of the above activities can put stress/excitement on the prostate and, as a result, trigger a falsely high PSA reading.

Good luck!
Chuck
