It may be your saddle
CYCLING over bumpy terrain or riding for long periods on a race bike with a thin saddle can be enough to trigger an injury to the prostate gland, says Christopher Eden, a urologist from the Royal Surrey County Hospital in England.
This can raise levels of prostate-specific antigen (PSA), a protein produced by the gland.
The risk is that if you have a PSA test after cycling, you could get a false raised result – raised PSA can be a sign of prostate cancer. “If your doctor does not account for this, some cyclists can find themselves undergoing unnecessary medical interventions such as biopsies,” says Eden. He suggests cyclists with a high PSA reading ask to be referred for a multiparametric MRI scan.
This looks at factors such as blood flow, and can be used as a screening tool without a painful biopsy. – Daily Mail
