Yes, unless you feel pain or irritation after riding. But waiting a few weeks couldn’t hurt.

Does anybody know or been told if after the gold seeds (fiducial markers) implantation and up to the radiation treatment sessions, if there is no SpacerOAR involved, it's okey to ride the bike? My gold seeds were implanted last We'd., March 26 and though Í asked my RO and care team, I was told that inmy case, spacer is not needed. (They told me the cases in which they, this particular cancer center, do spacer for their patients, so I have reason to believe them it's not needed in my case.) My SBRT treatments start on April 9.

Talk to your R/Os and or urologist.

Know that your prostate just went through radiation treatments and is in a state of high irritation and damage. My R/Os wanted me to wait a month to allow my prostate to lesson the irritation from the radiation to come down.

Just think about the little guy in there being bombarded with radiation damaging it big time. Probably having a really bad time from all the damage and irritatin and then you add a bike riding seat riding up into and putting pressur on it causing more irriation.

So my R/Os (had 2 different ones) and my PCP said wait several weeks. But go by what your R/Os and urologist give you for time frames. They may even recommend a shorter time or longer time depending on what side affects you had and are having.
