Re: 43 with Prostate promblems PSA 1.0 Question
The American Urological Association (AUA) publishes a document online called the "Prostate-Specific Antigen Best Practice Statement: 2009 Update". You can easily find this with an online Google search. It is fairly easy to read, and would be an excellent reference document for your to understand prior to going to your urologist...I highly recommend it.
In very general terms, 4.0 ng/mL has been the widely accepted threshold for looking more closely for Prostate Cancer (PC). However, the PSA test is (simply put) "imperfect" and PC risk exists even at traditionally low PSA values. Some of the statistics are in the AUA document.
As you will read in the AUA document (or other sources you may be referencing), a biopsy is the only definitive way to tell if you have prostate cancer. (But even a biopsy, which pulls out small samples of tissue, might miss cancerous cells, which generally form together in a clump.) However, there are other tests which might be valuable before jumping to a biopsy. After reading and becoming familiar with the AUA document, I suggest learning about these 2 additional tests, and consider asking your urologist about them: the "free-PSA" test, and/or the PCA3 test. (Google these for more info.) Both tests are intended to more clearly indicate whether a biopsy is necessary & appropriate.
