prostate cancer (PCa) is the most common cancer and men- and it is being detected in more and more younger men. Some feel it is over treated in America. They used to think a PSA over 4 indicated PCa. Now they realize that some men have large prostates and the PSA value is related to the size of the prostate. And as men age the prostate gets larger. Today the key indicator is the change in the PSA value over time. Most PCa grows very slowly- like over ten to fifteen years. so if the PSA is not changing very rapidly - probably not an issue.
