Can riding a bike before a PSA test cause a higher rating after a prostatectomy
Result
Yes, riding a bike before a PSA (prostate-specific antigen) test can potentially lead to a higher PSA reading, even after a prostatectomy. While the prostatectomy removes the prostate gland, any residual prostate tissue or inflammation can still be affected by physical activity, including cycling.
This is not news to me. After attending advanced prostate cancer online meetings for years, I have heard this story over and over. Some prostate cancer patients love to ride their bikes, They have been warned that doing it before a PSA test can cause higher results.

Actually, I was interested in your experience with other prostate patients, which is why I asked. I did ask Perplexity before asking you, but I received a pretty much opposite answer: "For men who have undergone a prostatectomy (removal of the prostate), riding a bike is generally not expected to cause an elevated PSA level because the prostate—the source of PSA—is no longer present. PSA is a protein produced by prostate cells, so without the prostate gland, PSA should be undetectable or very low.". But I suspected there'd be some feedback in the meetings you attend. Sorry if my question seemed trite; I won't make that mistake again.
