I did my first PSA test recently as part of a general health check, and then a retest. the results came in at between 3 and 4 which is just below the borderline for further investigation (at least here in CH). I am a keen cyclist and it is known that cycling can elevate PSA values slightly. A quick finger test showed no significant enlargement and the doc said it felt normal, but suggested regular retesting every 6 months to monitor for changes.
She would also schedule an MRI if I insist on it, but didn think it was necessary at this point. Let’s see what the values are in 6 months.
