Bicycling while on ADT & radiation okay?

Posted by guybe @guybe, Mar 31 7:36am

I'm new to ADT (on Orgovyx for 1 month now, abiraterone and prednisone in just the past few days, radiation coming soon). Winter is over around here, and I have four nice bikes (can't have too many) in the shed, wanting to hit the beautiful roads and trails around Washington DC for my usual 40-50 mile rides. I've heard that riding irritates the prostate, including temporary PSA elevation. Is that "irritation" and elevation ignorable, or would I be better off sticking to running and weights from the standpoint of treatment outcomes?

ok..you will prob have rectal spacer injected before radiation...so my advice is no riding for 3 weeks after spacer is injected so that you dont move the protective gel out of place...next, I would not ride over 10 miles at a time for now, particularly while you are being radiated and I would wear very padded biking shorts. Also, hydrate ALOT with ADT, especially on hot days...lastly, biking beofe PSA draws will make your PSA higher...all said, I think you can continue to bike, * ( except while spacer gel in settling)..if you notice any blood or extreme pain/discomfort, then stop.. I am a bike too and I hated my hiatus but glad I did it. Radiation can be tricky..side effects show up months down the road sometimes..months after you have finished..exercise is good for managing ADT side effects..just pay attention to what your body is telling you..!

@xahnegrey40 No spacer. I should have mentioned in my original post that I am having a recurrence of PCa, where it has metastasized into 2 lymph nodes near the prostate (which is clear). So, no SpaceOar this time around. Still, those lymph nodes' proximity to my "bike saddle bone" have me concerned that biking could adversely impact the radiation therapy's effectiveness, or throw it off in some way, and that's the heart of my concern.

ok..forgive me...well I dont think riding will be a problem ...I actually had 45 sessions of photon radiation last fall since I had small area of Gleason 8 in prostate ( 2 out of 14 and 2 Gleason 7---- total of 4 cores out of 12 ) + 2 pelvic lymph nodes that had small tracer uptake.
so I dont imagine cycling will be any problem at all since your radiation will target pelvic region...I imagine you will have some transient fatigue at times but since you are in very good health, I imagine you wont notice much. Good luck to you !! ( always discuss your questions/concerns with your oncologist/radiation team !)
