There is lot of information about prostate specific antigen.
Some of it is true, some is false.
And if you are relying on measuring it to determine if you have prostate cancer or not, then you may be in for a rude, painful awakening.
Here is why: Prostate specific antigen (also simply called "PSA") is a protein your prostate gland cells produce.
It tends to be present in lesser quantities in men with prostates that are healthy and functioning properly, with no problems.
But, it tends to be elevated in men who might have prostate cancer or other prostate problems.
How do they check your PSA? It is done with a simple blood test you can get at your doctor's office.
And, for many years it was considered the most effective way to test for early prostate cancer detection.
However, lately, people are finally starting to question the wisdom of this.
And the reason why is because it really is not always that accurate.
Yes, you should have it tested if your doctor or urologist suggest it.
But, whatever those PSA numbers are, do not take them as "gospel" that you do or don't have the disease.
Especially since, a lot of factors can alter your numbers at any time.
Even something as simple and routine as having sex with your wife the night before a blood test can alter your numbers! What is the point? If you are going to test your prostate specific antigen levels, that's good.
Just don't rely on those results as proof that you do or don't have prostate cancer.
