He says raised PSA levels caused by cycling, do not put the rider at any risk of cancer.
"Cycling does raise PSA levels but only temporarily. So the way to distinguish whether cycling has caused a rise in levels is to refrain from getting on a bike for 48 hours and then having a second PSA test. The levels will have dropped if cycling was responsible for the rise."
PSA tests measure the total amount of prostate specific antigen (PSA) in the blood. PSA is a protein produced by normal cells in the prostate and also by prostate cancer cells. It is normal for all men to have a small amount of PSA in their blood.
But a raised level can sometimes be a sign of prostate cancer which is why further investigation such as a biopsy is needed.
There is no screening programme, but men may be offered the test as part of a routine medical or health care check.
Mr Eden says any man over the age of 40 should know his PSA levels.
Each year about 36,000 men in the UK are diagnosed with prostate cancer, making it the most common cancer in men. It mainly affects men aged over 50.
According to Cancer Research UK although there has been a huge rise in prostate cancer incidence over the last 20 years, this has not been reflected in mortality rates - partly because of the use of the PSA test.
Mr Eden said: "The irony here is that physical exercise such as cycling is actually protective against prostate cancer since it`s a way to avoid weight gain and is generally a way to keep healthy. So it`s important that cyclists don`t get scared off from enjoying their hobby.
"I think any man who is a regular cyclist and who needs a PSA test should tell their doctor about their hobby. It`s surprising how many doctors may not know about the association and this could avoid unpleasant further investigation. Mentioning you regularly use your bike could save on a lot of discomfort."
